Well if they are calculating billions of years on the basis of measurable radiation one second at a time they're dealing with some VERY BIG numbers. I figured that they had some method of calculation. I won't argue with whatever answers they come up with. I suspect there are many fundamental properties of the universe that are simply beyond human comprehension anyway. But thanks for the info about cesium-133 and the measurable radiation.
One thing I always wonder about is how it can be determined that "the galaxy is ten billion years old" or what is the age of the universe. Our concept of a year is based upon one rotation of our planet around the sun. But our planet is estimated to be only four billion years old. What unit of measurement is being used to calculate the existence of other celestial objects that existed long before our earth and sun did? I'm guessing that such numbers are largely guesswork also.
@JackKangaroo1 The natural periodicity of the radiation of a cesium-133 atom is defined as exactly one second, and it all goes from there. But you can argue that atomic properties took time to become what they are now after the big bang, so take it how you will.
Cosmic background radiation is used to measure the expansion of the universe, which physicists use to extrapolate back to the big bang with complex math that frankly goes over my head.
The sheer numbers of stars and planets offers a probability that out there somewhere are worlds conducive to life and that life exists on these other worlds. But the sheer vastness of the universe also makes it highly improbable that any contact between intelligent life forms will ever occur. If it does at all, it will be through an accidental convergence of worlds coming close enough for contact. But this also requires that such life forms exist simultaneously; another long shot in the Heavens.
@benthemeister go watch Nial Degrasse Tyson on Intelligent Design theory, ge rips it to shreds and does so magnificantly, im sorry but the idea of all physicists agreeing with intelligent design is either bullshit or means we need new physicists.
I thought science was dependent on what we can observe,express and or quantify. Has anyone ever seen a little green man, a gray, or even an extraterrestrial living cell much less a sequence of numbers showing an advanced extraterrestrial intelligence? Maybe Tysons right. The folks at SETI continue to hope (as he does also). I would also add in the words.... having faith.
@VaporGraph According to Paul Davies "There is now broad agreement among physicists & cosmologists that the universe is in several respects ‘fine-tuned' for life" Yet we only know of 1 type. Terrestrial life. Rodger Penrose has calculated the initial conditions of the universe as being so specialize as have a chance of 1 10^10^(123 of happening on its own. This is great observable evidence for a creator. SETI has nothing close to these exponential values which make the Drake equation look silly.
We beings are part of the universe (e), are like nomads. After an earth is exhausted, we move on to another planet. In the beginning, humans were from another place out there. Those celestial beings by curiosity came down to earth because the earth looks so beautiful. They came to experience their life and death, and then they go home. So They, meaning us now, are here to play the game of life and death. All is just like a game, a play on the big theater of Samsara, everyone is an actor.
you know, we are really close to the milky way where theres an enormous blackhole an the galaxy is a giant funnel(the bottom is that black hole). if we go away from the milky way we might find other places with living organisms. the only problem is we need an extremly strong fuel resource for the rocket thats being used. if we find that resoucre, we might be able to go to the extreme as to land on a planet far away from earth.
What if aliens showed up and they were kind of stupid...they just had a 100,000 year head start or had a stacked deck when it came to energy resources. Once we got our hands on their tech we would dominate them. It could be that certain alien species know we exist but are scared to let us get their technology because of our intelligence and violent tendencies.
@4XxMETALGEARSOLIDXx2 Just because they have more advanced technology doesn't necessarily mean they are more intelligent. That was my point. I wouldn't consider myself more intelligent that someone from the 1600's just because I have a cellphone and know how to take apart a computer.
@csbob2010 Let's take Gliese 581c as an example here. It's relatively close, at twenty light years away. In order for them to actually come here in a decent amount of time, their technology is far, far beyond ours. The headstart that you mentioned earlier would only allow them more time to evolve to become more intelligent.
I see your point though. Individually, we might hold a candle to a portion of their population. But on a general scale, they'd be more intelligent.
@tideway BUT, how far away are alien life, if they were in another solar system then it would take a day to reply, if we were the only civilization in our galaxy then it would take centuries.
It's annoying to read conspiracy claims about SETI. Anyone can sign up and let their computer run in the background to help the project analyze data. As to government control of SETI, there ain't no such thing. The US contributed funding during SETI's early years, sure, but now it's a collective of independent enthusiasts who are privately funded. I'm one of them and, as far as I know, I'm a free man - just like Patrick McGoohan in "The Prisoner"!
Wouldnt it be the greatest news story of the last 100 - no. EVER - if we found other intelligent life out there? Even if it's 500 Lightyears away and communication takes thousands of years.
People think that if S.E.T.I finds a signal, they will tell the world about it the next day! Dream on...the US government will never let that happen, they control S.E.T.I !
Stop with the conspiracy theories... Information like this is impossible to contain. Everyone who has it will try to share it, even if it means being prosecuted by the government. The people at SETI have dedicated their lives to finding extra terrestrials and even if the government tries to contain the information, they would still go against it and tell the media, regardless of what happens to them afterwards.
Remove yourself from the human perspective for a moment - pretend you're a non-human observer somewhere else in the universe, and say 'is there any life in the universe?'. The answer is yep! If life can happen in one place, it can happen any old where. I think most alien life will be very mundane and not much like us at all, but hey - at least it's there. It's the biggest zoo in the cosmos. I wish I could live to see it explored.
We are not alone. There are billions of galaxies, with trillions of planet in them all. The odd of there being alien is pretty much ABSOLUTE. If they're like the human species...that's very extremely low.
Yes there are vast distances, but as weall are basically dancing percariously expanding bubble of time and space who is to say there are uncountable civilizations past present and future that have and will be doning the same thing. What if some of them had traveled vast distances thus bridging the distance between us and happen to pick up our radio signal. No we are most certainly not alone...and that is a good thing.
I highly doubt we are the first. However, I "highly doubt" that we could see "them". As we will, they have already (within just a few millennia) developed robotic, and then quantum "bodies". They "appear as spirits"? Remember, millennia is a very tiny blink in cosmic time...

Neil deGrasse Tyson - "OUR COLLECTIVE FREE TIME NEEDS TO SHIFT AS MUCH AS POSSIBLE TO EDUCATION. WHETHER YOU'RE A YOUNG STUDENT OR FINISHED SCHOOL LONG AGO, GET OUT TO THE LIBRARY WHENEVER YOU CAN AND WORK HARD TO LEARN EVERYTHING YOU CAN ABOUT THIS WORLD. EACH INDIVIDUAL AND SOCIETY WILL BENEFIT FROM BEING ABLE TO SOLVE MORE PROBLEMS AND MAKE BETTER DECISIONS. EDUCATION IS AN AMAZING DISCOVERY PROCESS THAT REPAYS YOU ENDLESSLY."
only a true idiotic moron still believes that we are alone and special in the universe. the sofar and ever increasing known of stars in the seen spectrum from hubble is 250,000, 000,000,000, 000,000,000 stars--- and thats only a fraction of the universe.. tyson is therebye confirmed an idiot among billions on this earth for fucking thinking of a chance of us being alone.OMG, we arent only among others, we llive in a living universe full of life both lower and far superior
@leviterande Asking if we are alone is different than assuming we are alone. There is no evidence we are not alone, thus as a scientist, he must ask these rhetorical questions.
@leviterande why? because of your pathetic attempt at understanding the sciences?
We don't have the answer to whether Aliens do exist or not. It may seem obvious that due vastness aliens must exist but that doesn't mean we just ignore the how ever slight possibility that Aliens don't exist.
Science has the capacity to be wrong. As is proven, funnily enough, by science.
@leviterande But yet you're the one showcasing the "little minded"ness...Y'know, the way you present yourself and your flawed argument is not much different to how fundamental religious types present themselves and arguments.
You're too close minded to be able to appreciate true science no matter how much you pretend to.
Where did I say there was no life in the Universe?
I've stated that to approach alien existence scientifically you must also accept the how ever small possibility of no alien life. Until we've made contact with aliens or discovered some equation that proves aliens we have to explore both possibilities.
@Oxymoron028 Science doesn't presume there is any life, and it's limited to speculating on the odds of it occurring. Given the monstrously absurd vastness of the universe, the odds are generally considered good. I'm not sure where you're going with talking about accepting that there may be no life. Yes, that's technically a possibility...but it's unprovable, and I don't see there being any implications where it even factually true - yet the implications of life (if discovered) are great.
Looking for aliens like this is like fish in a fish tank looking for kangaroos. Good luck with that scientists. Wouldn't be so bad but the 'Government' spends BILLIONS of tax players' cash making all these telescopes and equipment when the human race/ planet obviously has many more serious and very real problems to solve.
@ZachCraft Explain? How can you look at the size of our universe and how infinitesimally minute we are as a solar system, take into account the number of solar systems and come to the conclusion we're alone?
@ZachCraft If something has a 99.999recurring% chance, it's pretty damn unlikely it won' happen. If you don't even know what probability is or the drake equation, i'm wasting my time.. Goodbye
I'm well aware of what the probabilities are and what the Drake equation is. Apparently you couldn't make the connection between "something happening", which I addressed, and the probabilities.
@ZachCraft The universe is roughly 15 billion yrs old and the Earth is around 4.5 billion , if you do the math, the rest of the universe has a 10 billion yrs head start on us, are you going sit there and say that there were nothing happening during that time before we came to be? And don't forget, life didn't start here until recently (geologically speaking). If just only 1% of the Drake equation holds water, there would be millions of civilizations in the cosmos.
@mysteakhouse Plus life on Earth got as far as the Dinosaurs then nearly went back to scratch. If life on another planet started at the same time as the Earth but didn't have an ELE like the one that killed the dinosaurs it might have a 65 million year start on us.
all the most common elements on our earth are just as common out in the universe!!
amino acids have been found on asteroids and that might have had a hand in our creation.
scientists say that some form of liquid is needed to help get things moving and on the moon "Titan" its so cold that methane actually rains from the sky and it has oceans!!!!!!, hell another moon Europa might have an ocean under the ice covered surface!!!!
@mysteakhouse and dont forget that the Drake equation only applies to the milky way(no, i didnt know that either until recently). when you tweak and apply the drake equation to the entire universe, the number of planets with "intelligent" life on them increases exponentially. Intelligent life in the universe is a mathematical certainty.
@mysteakhouse I agree with you in your conclusion, but some of your mathematical interpretation is off. While it is true that the universe is about 9.21 billion years older than earth, at least a few billion years of that time would not allow the evolution of life. First, stars had to form and pump out heavier elements. Life has existed on earth for most of its history, at least 3.5 billion years. Multicellular life has been here for 1.7 billion years. So life is not recent geologically speaking
@mysteakhouse well gotta factor in creation of a sun and the planet which I believe vary greatly if i remember right. but other life is pretty much a fact since it's impossible for only one planet out of trillion of trillions to have life.
Now in terms of aliens coming to earth i thinks that BS, but having advance civilizations out there equal, greater or lesser then ours is pretty much certain, plus explore space to discover and find life, not stay unknown to other life.
You have to remember that the early Universe was chaotic. The first life in the Universe probably arose after at least several billion years after the big bang. Still though, the Universe has been relatively stable for many billions of years, and there's probably life out there with a significant head start on us.
Please visit my channel for the unpopular truth about homosexuality.
A person does not need hatred or any kind of phobia in order to acknowledge important, qualitative differences between heterosexual attraction / behavior / marriage / adoption and homosexual attraction / behavior / marriage / adoption.
Homosexual activists, with complete support from the media, have succeeded at framing themselves as noble victims and martyrs; it's an effective way to push a social agenda.
I think it would be a HUGE waste of potential if our universe was filled with unimaginable worlds with life and intelligence yet so far from each other that they will never be aware of each others existence? it just SUCKS. Why would god design the universe like that?
@GeneralRushHour I am an ATHEIST, that was my way of proving that there is no god. I consider this type of universal design to be proof at LACK of god because of the horrible waste. Do you realize what a horrible waste it is that there are probably more populated worlds in the universe than there are rice grains in Asia ours being just ONE of them and none of these worlds will ever be able to communicate with each other?
@Zurround100 I see sorry i just read the Why would god design the universe like that? part :)
yes i realize that, but i feel that is part of the game. It will take thousands of years until some civilization "levels up" and have the ability to do that type of stuff.
To me life is really a game if you think about it. "Without a designer i should say"
Your life is a game, mankind is also in on it´s own game by surviving etc.
It´s all about surviving and get to the next level.
We have the unique privilege of fossil fuels. It's standing on what has died beneath our feet that allowed us to conquer disease and discover the properties of our universe. If another intelligent species has to be anything like us, they might require that "boost" as well. It's a shame we're wasting this (quite literally) infinitely valuable resource on killing our own species. When it's gone, it'll probably take another 250 million years for another intelligent species to try again.
@ataryo It's simple. If we had never discovered coal and oil, where would we be now? Before that we had to use water, wind and burning wood. Would we have found solar power? Geothermal? Tidal? Nuclear?
@aphoxema I agree,but now those kind of energy fuel are harmfull for us and the planet.Its by being able to take the energy which is unlimited(water,wind,sun) and clean that we could move to another level of techonologies and healthy prosperities.
@aphoxema if we master those energy and they become extremely efficient.then energy cost we become cheaper and cheaper cause they are unlimited.By becoming cheaper, the research and technologies engineering will also become cheaper and our technological growth will skyrocking.
@ataryo I'm not talking about where we can go from here, I'm talking about how we got to where we are. If things hadn't died for hundreds of millions of years and slowly built up a high density energy goo, we could not possibly reach the level of technological awareness that we are at now. The point is, another sentient species on another planet would -probably- have to have the same luck as we did. It's a matter of opportunity.
@aphoxema I dought about it.Different planets have different minerals,also we must not evaluate an other non human civilation according to human standard.
@ataryo Neil just made the point here that we are the product of the most naturally abundant materials in the known universe and that other lifeforms will probably be the same. This isn't a human standard, this is the incident of nature investing into a sentient species that can become aware of the properties of the universe. Energy, a hell of a lot of energy, was critical in our enlightenment and it was the excess if fossil fuels that provided for our survival and knowledge.
Considering the vastness of space and the number of galaxies, it seems entirely likely that there could be another planet just in the same position as earth with just the same type of highly-evolved intelligent life that looks just like us humans. Let alone the possibility of other life... I think that it is simply probability.
I think a bigger question is: Who are we? Where are we? And why are we? What am "I"? I would like those answered before I care about whether "we" are alone.
@Ermal8711 Who are we: We are human beings; we are a species of primate which has evolved over millions of years. Where are we: planet Earth, an insignificant planet in an insignificant solar system in an insignificant galaxy. Why are we: depends in what sense you mean by "why". What am "I"? "I" is a social construct which sets an individual apart from a group.
@Emanresu56 Let me establish something: I am not arguing for god. I am just saying, we were born; we have a conscious existence and experience that is individual... We simply have no actual definition for anything as to what we or our world is or where it is. There is such an immense disconnect here. We are simply born with a consciousness that we cannot even begin to contemplate. This is really just musings of my own mind. This all seems so absurd.
Well how do we know an alien signal would even be in our detectable range? There could could be all types of alien signals out there that we can't even tune into.
The universe too big for there no other intellegent life, but extermly rare. Super advanced aliens that's a million times more then us? Maybe,maybe not. Space is just to vast for travel and the laws of physics too limiting, only in science ficton. We should have picked up signals by now. The universe is designed for life under the right conditions. Intelligent life is very rare, but can happen. Just look at our solar system. One know panet with life and only one species that's intellegent.
People always assume that there is some all knowing powerful alien race out there. What if we are the first. What if in a million years, we are that powerful alien race who has mastered galactic space travel etc... Also, people assume that aliens would be like us. We probably wouldn't recognize intelligent life, even if it was right in front of us. We also assume we're the one intelligence on our planet. What if the planet is an intelligent life form, or some plant in the amazon...think about it
There is a tendency called "convergence" in nature. It occurs when multiple species arrive at a very similar anatomy independently because that shape works so well. Of course there is no way to predict what aliens might look like... unless you know alot about their environment. If an alien environment is similar enough to our own, the creatures that evolve there could look very familiar.
Proposing that the planet itself is alive is just not a defendable postition.
@drche420 We have no frame of reference besides our own planet which shows how incredibly diverse life can be. Humans pulled ahead, but even a slight change in an environment would have changed that. Bottom line is that we don't know much and even what we think we know to be true is subject to change. Thinking that aliens look anything like primates seems a bit egocentric.
If we could pour the money and brainpower that works on trying to find out out if we are alone, into trying to solve the realtime problems we face on THIS planet, we might, just might, have a better understanding of ourselves. Physician heal thyself. Quit looking for aliens. Quit looking for "God".
What if........We are alone? How depressing would that be to know that there is no one else out there! If it is possible that we aren't alone would it also be possible that we are??
@bizzlesnatch I bet in a thousand years historians will look back at discussions in Youtube etc...and to them it will be like reading some scratch on a wall made by some cavemen. They will watch news, tv shows, read papers etc.. and be like "Wow these people were fucking stupid". Point is, we are stupid. We can't speculate on things that according to science, don't exist. We can only go off of what we find and discover. Until we discover them, they do not exist. Period.
@csbob2010 Yeah, but at least now days people are becoming more open minded, if someone has a wild idea od a 4th demention, or a theory of how black holes warp time, at leats people are open to hear the idea. I have been watching alot of Morgan Freeman's into the wormhole, and Wonders of the universe on SCI channel. Lots of good ideas and thoughts. Back a 1,000 years you would be stoned for thinking the earth wasn't flat. I believe the more we look at the stars...the more we will see!!
Most likely we will never know if we are alone or not. We don't even know how life started here on Earth in the first place, so the real question is not whether there is intelligent life elsewhere in the Universe but how possible it is that ANY life has emerged somewhere else. But even if there is intelligent life elsewhere, it is utterly unlikely that it is detectable for us because if it exists, it is bound to be millions or hundreds of millions of years ahead of us.
a few hundred years ago most white people thought black people were animals and enslaving them was no worse than enslaving an ox or any other "beast of burdon". Neuroscientists many decades ago actually said that black people had a genetic predisposition that prevented them from being as smart as white people. I wonder how any of these people would explain Mr Tyson?
While we have been using radio for 100 years, we are somewhat moving away from it. Perhaps in 100 years from now, we'll be past that, and be using more efficient, yet harder to detect mean of communication, say a laser shoot from point to point as an example.
SETI's problem maybe confounded by the small window of time in which other civ's use currently detectable means of communication.
@Craigmw45 The reason radio waves work is because they do not require line of sight. We rely on satellites for the state of the art communications at the moment. They serve as a relay hub for communications, although they quality of those are determined by the position of the satellites. Radio waves are very primitive, or so we think, but are extremely effective. I don't see us find something better that work for a while. I think broadcasting our existence to aliens in space is a bad idea.
@hellhammerz666 i tend to agree with you, i mean it was only a few years ago that dwelling in caves we found a non carbon life form, previously we had thought that all life on earth was a form of carbon lifeform but this lifeform turned out to be somethin different, it could only be found in 1 place cuz the circumstances for it to live was rare, granted this stuff looks like snotters hangin from rock but life all the same so given its ecosystem im not ready to rule out life on other planets.
that "1 time theory" does not equate with the insurmontable evidence of past civilizations far more advanced than our own leaving bits and pieces of culture. not only that but the crust displacement "theory" points to the fact that nature has a sort of 'reset' button for a civilization that develops on any continent.
How can he say that we are the only species that have mastered technology? Other prime-ape species have been able to use tools in the past. I guess it all depends on how one defines technology...
@mentalmercury11 Not to mention there are also certain birds that use tools as well. What the greatest scientific discoveries have in common is the dethronement of human arrogance.
@mentalmercury11 I believe there is a difference in the ability to pick up an object and use it as a tool, and the ability to take objects and craft them into tools. The later being more impressive and more embodies technology (in my opinion). Also when looking for intelligent life on other planets we need to define intelligence (and so their level of technology) to be at a level that will allow us to find them or them to find us.
@DrunkenScuba Yes that is true, but even in that aspect we are not alone. I am sure that other hominids that came before homo sapiens sapiens were able to craft objects. I think we both agree in the fact that a lot more needs to be added in terms of definition. Scientists for example have drawn the line between Communication and Language (any language is a form of communication, however not all communication is language. Set theory FTW), and I think the same needs to be done for technology.
Could the universe be too young for extraterrestrial to contact each other? If other intelligent life evolved at the same time we have and is 1000's of light years away they would not know we are here neither. In 1000's years they may start detecting our signals. By then we may both be gone? Then again they may have sent signals to us 1000's of years ago and those messages may be about to reach us. Who knows?
when someone tells you that the universe was created by a random event we call the big bang , if you have a human brain your normal response would be : and what created the thing that created the big bang ?? let's assume he answers you , then you'll ask what created the thing that created the thing that caused the big bang ???? if he answers you ask again !! so for this conversation to and he must come to the point where he tells you that thing was created by an entity that cant be created !!...
"he must come to the point where he tells you that thing was created by an entity that cant be created !!..."
No, it could very well be that big bangs are pumped out of the breathing of eternity that in essence could be a mechanical process. It's just as likely that my process invented on the spot is correct as any other silly solution like the Flying Spaghetti Monster, Allah etc. Snap out of it. Your old book is just yesterday's news and the big bang can be calculated at least!
Yeah, they have the bible, tarot cards, faith, spiderweb and the past ...
...and we have the big bang, abiogenesis, evolution, DNA, the fossil record, the transitional forms (at least to the point beyond the shadow of a doubt), logic, reason, astronomy, space travel, particle accelerators, gravity, strong/weak forces, relatitvity, biology, physics, chemistry, electronics, computers, the phylogenetic tree and the future so forgive me if I forgot the background radiation : )
Thing is, one species has risen to technology on earth, and you could argue that others haven't because one HAS. So would it then be fair to assume that each life-sustaining planet has the potential for one species of technological intelligence?
@MachineExperiment0 I'm not sure if I totally understand what you mean, but I certainly agree that humans are not that intelligent, we are only a few steps ahead of the Apes. We have developed some highly advanced technology but don't really have the intellect to live together is a peaceful and none destructive way.
The argument that intelligent life if rare because only one species developed intelligent life out of millions is ridiculous. You have to look at it like this, the earth has developed intelligent life at least once over it's existence. This means that there will be thousands if not millions of planets that have developed intelligent life. It has nothing to do with how may species live on the planet. Who knows, the earth might have developed multiple intelligent life forms over it's existence.
@ItsNotEvenSunny I agree that is rare on earth, but that say's nothing about the how much intelligent life is in the universe. If every galaxy contained only one form of intelligent life, then there would be over a billion species of intelligent life in the Universe, do you call that rare, I am not too sure. I would imagine there would be at least 1000 intelligent life forms for every galaxy and probably over 100 aliens visitations to earth.
@nikolayzou well yes thats true but you're misunderstanding 'rare'. if say.. diamonds were rare, and lets say there were only 1 in every country thats still almost 200 diamonds, now people could say thats alot of diamonds globally, but if you're confined to 1 country and you only know for a fact that only 1 diamond exists.. then it can be considered rare. what im trying to say is look at it in proportion
Our perspective on alien life is measured trough a momentum.
When thousands or millions of atoms are smashed in a hydron collider we dont say nothing has happened. Cause the microscope proves significant parameters.
When we look at the stars we say nothing happens, it just stands still. Only the Dr in the university or the fan to the subject knows the relativity of time. The universe is nothing more then a hydron collider on a larger scale.
every matter in the universe was one attached to each other, or channeled trough a void or dimension from which it came. And everything has once collided with one another.
Wherever life came from, it had 12billion years to jump from one galaxy to the other.
Im honestly positive that life is present in proportion that matches the game spore. Sorry for comparing reality to a game, but it was a very accurate picture of how i view extraterrestial life.
The reason that our world is fueled on facts rather then logic aproach is because its in our nature to fear se we isolate our ability to reason cause if everybody used reason it would have been painly obvious for everyone (instead of just me and you) that the universe must be teaming with life.
Its like DR kaku said.
Your not going to look for a ant hill and supply it with their needs.
Wether that difference in evolution is meassured in size
(human vs ant) or in consent and biological perks is a mystery.
Remember, dinosaurs once walked the earth. They could contain their size because of the greater amount of oxygen that was then present on earth.
Imagine a rocky planet several times the mass of earth with a lower density then earth.
It would allow even bigger creatures.
I dont think were advanced. I do think that humans are on a important stage in evolution. We cant even get humans pass earths orbit. Other species are there
that travel the stars. Although it might be portrayed as if near future space travel might take only several hundred years. Were far far further away from that.
@nikolayzou what im trying to say is look at it in proportion, like you said "f every galaxy contained only one form of intelligent life, then there would be over a billion species of intelligent life in the Universe" but that would mean that there are over 100Trillion species to compare that too, 1billion out of 100trillion does that not seem rare? thats literally 1 in a million by ratio. pretty much the definition of rare :P
@ItsNotEvenSunny When you mean species, are you referring to intelligent life or all forms of life? I think when comparing intelligent life to none intelligent life you can say intelligent life is rare. But still, that means that there is a hell of a lot of intelligent life in the Universe and since the Universe is over 12 Billion years old, then surly Aliens have visited earth or are hear already, it's all probability.
Well if they are calculating billions of years on the basis of measurable radiation one second at a time they're dealing with some VERY BIG numbers. I figured that they had some method of calculation. I won't argue with whatever answers they come up with. I suspect there are many fundamental properties of the universe that are simply beyond human comprehension anyway. But thanks for the info about cesium-133 and the measurable radiation.

One thing I always wonder about is how it can be determined that "the galaxy is ten billion years old" or what is the age of the universe.

What unit of measurement is being used to calculate the existence of other celestial objects that existed long before our earth and sun did? I'm guessing that such numbers are largely guesswork also.
JackKangaroo1 15 hours ago
@JackKangaroo1 The natural periodicity of the radiation of a cesium-133 atom is defined as exactly one second, and it all goes from there. But you can argue that atomic properties took time to become what they are now after the big bang, so take it how you will.
Cosmic background radiation is used to measure the expansion of the universe, which physicists use to extrapolate back to the big bang with complex math that frankly goes over my head.
csmith0191 12 hours ago
The sheer numbers of stars and planets offers a probability that out there somewhere are worlds conducive to life and that life exists on these other worlds. But the sheer vastness of the universe also makes it highly improbable that any contact between intelligent life forms will ever occur.

I thought science was dependent on what we can observe,express and or quantify. Has anyone ever seen a little green man, a gray, or even an extraterrestrial living cell much less a sequence of numbers showing an advanced extraterrestrial intelligence? Maybe Tysons right. The folks at SETI continue to hope (as he does also). I would also add in the words.... having faith.

@VaporGraph According to Paul Davies "There is now broad agreement among physicists & cosmologists that the universe is in several respects ‘fine-tuned' for life" Yet we only know of 1 type. Terrestrial life. Rodger Penrose has calculated the initial conditions of the universe as being so specialize as have a chance of 1 10^10^(123 of happening on its own. This is great observable evidence for a creator. SETI has nothing close to these exponential values which make the Drake equation look silly.

We beings are part of the universe (e), are like nomads. After an earth is exhausted, we move on to another planet. In the beginning, humans were from another place out there. Those celestial beings by curiosity came down to earth because the earth looks so beautiful. They came to experience their life and death, and then they go home. So They, meaning us now, are here to play the game of life and death. All is just like a game, a play on the big theater of Samsara, everyone is an actor.

What if aliens showed up and they were kind of stupid...they just had a 100,000 year head start or had a stacked deck when it came to energy resources. Once we got our hands on their tech we would dominate them. It could be that certain alien species know we exist but are scared to let us get their technology because of our intelligence and violent tendencies.

@csbob2010 Let's take Gliese 581c as an example here. It's relatively close, at twenty light years away. In order for them to actually come here in a decent amount of time, their technology is far, far beyond ours. The headstart that you mentioned earlier would only allow them more time to evolve to become more intelligent.
I see your point though. Individually, we might hold a candle to a portion of their population. But on a general scale, they'd be more intelligent.

It's annoying to read conspiracy claims about SETI. Anyone can sign up and let their computer run in the background to help the project analyze data. As to government control of SETI, there ain't no such thing. The US contributed funding during SETI's early years, sure, but now it's a collective of independent enthusiasts who are privately funded. I'm one of them and, as far as I know, I'm a free man - just like Patrick McGoohan in "The Prisoner"!

Remove yourself from the human perspective for a moment - pretend you're a non-human observer somewhere else in the universe, and say 'is there any life in the universe?'. The answer is yep! If life can happen in one place, it can happen any old where. I think most alien life will be very mundane and not much like us at all, but hey - at least it's there.

@Oxymoron028 Science doesn't presume there is any life, and it's limited to speculating on the odds of it occurring.

@mysteakhouse I agree with you in your conclusion, but some of your mathematical interpretation is off. While it is true that the universe is about 9.21 billion years older than earth, at least a few billion years of that time would not allow the evolution of life. First, stars had to form and pump out heavier elements. Life has existed on earth for most of its history, at least 3.5 billion years. Multicellular life has been here for 1.7 billion years. So life is not recent geologically speaking

Now in terms of aliens coming to earth i thinks that BS, but having advance civilizations out there equal, greater or lesser then ours is pretty much certain, plus explore space to discover and find life, not stay unknown to other life.

You have to remember that the early Universe was chaotic. The first life in the Universe probably arose after at least several billion years after the big bang.

There is a tendency called "convergence" in nature. It occurs when multiple species arrive at a very similar anatomy independently because that shape works so well. Of course there is no way to predict what aliens might look like... unless you know alot about their environment. If an alien environment is similar enough to our own, the creatures that evolve there could look very familiar.
Proposing that the planet itself is alive is just not a defendable postition.

Most likely we will never know if we are alone or not. We don't even know how life started here on Earth in the first place, so the real question is not whether there is intelligent life elsewhere in the Universe but how possible it is that ANY life has emerged somewhere else. But even if there is intelligent life elsewhere, it is utterly unlikely that it is detectable for us because if it exists, it is bound to be millions or hundreds of millions of years ahead of us.

They serve as a relay hub for communications, although they quality of those are determined by the position of the satellites. Radio waves are very primitive, or so we think, but are extremely effective. I don't see us find something better that work for a while. I think broadcasting our existence to aliens in space is a bad idea.

@hellhammerz666 i tend to agree with you, i mean it was only a few years ago that dwelling in caves we found a non carbon life form, previously we had thought that all life on earth was a form of carbon lifeform but this lifeform turned out to be somethin different, it could only be found in 1 place cuz the circumstances for it to live was rare, granted this stuff looks like snotters hangin from rock but life all the same so given its ecosystem im not ready to rule out life on other planets.

that "1 time theory" does not equate with the insurmontable evidence of past civilizations far more advanced than our own leaving bits and pieces of culture. not only that but the crust displacement "theory" points to the fact that nature has a sort of 'reset' button for a civilization that develops on any continent.

How can he say that we are the only species that have mastered technology? Other prime-ape species have been able to use tools in the past. I guess it all depends on how one defines technology...

@mentalmercury11 Not to mention there are also certain birds that use tools as well. What the greatest scientific discoveries have in common is the dethronement of human arrogance.
mentalmercury11 7 months ago
@mentalmercury11 I believe there is a difference in the ability to pick up an object and use it as a tool, and the ability to take objects and craft them into tools. The later being more impressive and more embodies technology (in my opinion). Also when looking for intelligent life on other planets we need to define intelligence (and so their level of technology) to be at a level that will allow us to find them or them to find us.

@DrunkenScuba Yes that is true, but even in that aspect we are not alone. I am sure that other hominids that came before homo sapiens sapiens were able to craft objects. I think we both agree in the fact that a lot more needs to be added in terms of definition. Scientists for example have drawn the line between Communication and Language (any language is a form of communication, however not all communication is language. Set theory FTW), and I think the same needs to be done for technology.
mentalmercury11 7 months ago
@mentalmercury11 Yes, I would agree with that.

I don't know why people who are so called religious say there isn't any other life in the universe.
If a God wants to make other species he can do what ever he wants.
If you think of it Angels are technically aliens.... They are not of this world so they are aliens....
In the bible it says In Heaven, we’ll see clearly (1 Cor. 13:12)
so you can't rule out that there are no other species in the world...
Remember when the world was flat?

Could the universe be too young for extraterrestrial to contact each other? If other intelligent life evolved at the same time we have and is 1000's of light years away they would not know we are here neither. In 1000's years they may start detecting our signals. By then we may both be gone? Then again they may have sent signals to us 1000's of years ago and those messages may be about to reach us. Who knows?

when someone tells you that the universe was created by a random event we call the big bang , if you have a human brain your normal response would be : and what created the thing that created the big bang ?? let's assume he answers you , then you'll ask what created the thing that created the thing that caused the big bang ???? if he answers you ask again !! so for this conversation to and he must come to the point where he tells you that thing was created by an entity that cant be created !!...

"he must come to the point where he tells you that thing was created by an entity that cant be created !!..."
No, it could very well be that big bangs are pumped out of the breathing of eternity that in essence could be a mechanical process. It's just as likely that my process invented on the spot is correct as any other silly solution like the Flying Spaghetti Monster, Allah etc. Snap out of it. Your old book is just yesterday's news and the big bang can be calculated at least!

Yeah, they have the bible, tarot cards, faith, spiderweb and the past ...
...and we have the big bang, abiogenesis, evolution, DNA, the fossil record, the transitional forms (at least to the point beyond the shadow of a doubt), logic, reason, astronomy, space travel, particle accelerators, gravity, strong/weak forces, relatitvity, biology, physics, chemistry, electronics, computers, the phylogenetic tree and the future so forgive me if I forgot the background radiation : )

Finding intelligent extra-terrestrial life before our own self destruction/immortality is highly unlikely.

Billions of galaxies, each galaxy has billions of planets and stars. The probability is extremely high that there is other life out there.

Thing is, one species has risen to technology on earth, and you could argue that others haven't because one HAS. So would it then be fair to assume that each life-sustaining planet has the potential for one species of technological intelligence?

If there is life in the great beyond, we'll have to come up with a better way to talk about them than using the word, "aliens".

@MachineExperiment0 I'm not sure if I totally understand what you mean, but I certainly agree that humans are not that intelligent, we are only a few steps ahead of the Apes. We have developed some highly advanced technology but don't really have the intellect to live together is a peaceful and none destructive way.
nikolayzou 8 months ago
The argument that intelligent life if rare because only one species developed intelligent life out of millions is ridiculous. You have to look at it like this, the earth has developed intelligent life at least once over it's existence. This means that there will be thousands if not millions of planets that have developed intelligent life. It has nothing to do with how may species live on the planet. Who knows, the earth might have developed multiple intelligent life forms over it's existence.

@nikolayzou what he was saying is that we're 1 in a million.. thats pretty rare if you ask me..
ItsNotEvenSunny 8 months ago
@ItsNotEvenSunny I agree that is rare on earth, but that say's nothing about the how much intelligent life is in the universe. If every galaxy contained only one form of intelligent life, then there would be over a billion species of intelligent life in the Universe, do you call that rare, I am not too sure. I would imagine there would be at least 1000 intelligent life forms for every galaxy and probably over 100 aliens visitations to earth.
nikolayzou 8 months ago
@nikolayzou well yes thats true but you're misunderstanding 'rare'. if say.. diamonds were rare, and lets say there were only 1 in every country thats still almost 200 diamonds, now people could say thats alot of diamonds globally, but if you're confined to 1 country and you only know for a fact that only 1 diamond exists.. then it can be considered rare. what im trying to say is look at it in proportion

Our perspective on alien life is measured trough a momentum.
When thousands or millions of atoms are smashed in a hydron collider we dont say nothing has happened. Cause the microscope proves significant parameters.
When we look at the stars we say nothing happens, it just stands still. Only the Dr in the university or the fan to the subject knows the relativity of time. The universe is nothing more then a hydron collider on a larger scale.

every matter in the universe was one attached to each other, or channeled trough a void or dimension from which it came. And everything has once collided with one another.
Wherever life came from, it had 12billion years to jump from one galaxy to the other.
Im honestly positive that life is present in proportion that matches the game spore. Sorry for comparing reality to a game, but it was a very accurate picture of how i view extraterrestial life.
Although i do say that advanced lifeforms may
Armigo91 8 months ago
be rare to find. But who knows.
Remember,
The reason that our world is fueled on facts rather then logic aproach is because its in our nature to fear se we isolate our ability to reason cause if everybody used reason it would have been painly obvious for everyone (instead of just me and you) that the universe must be teaming with life.
Its like DR kaku said.
Your not going to look for a ant hill and supply it with their needs.
Wether that difference in evolution is meassured in size
Armigo91 8 months ago
(human vs ant) or in consent and biological perks is a mystery.
Remember, dinosaurs once walked the earth. They could contain their size because of the greater amount of oxygen that was then present on earth.
Imagine a rocky planet several times the mass of earth with a lower density then earth.
It would allow even bigger creatures.
I dont think were advanced. I do think that humans are on a important stage in evolution. We cant even get humans pass earths orbit. Other species are there

that travel the stars. Although it might be portrayed as if near future space travel might take only several hundred years. Were far far further away from that.

@nikolayzou what im trying to say is look at it in proportion, like you said "f every galaxy contained only one form of intelligent life, then there would be over a billion species of intelligent life in the Universe" but that would mean that there are over 100Trillion species to compare that too, 1billion out of 100trillion does that not seem rare? thats literally 1 in a million by ratio. pretty much the definition of rare :P
ItsNotEvenSunny 8 months ago
@ItsNotEvenSunny When you mean species, are you referring to intelligent life or all forms of life? I think when comparing intelligent life to none intelligent life you can say intelligent life is rare. But still, that means that there is a hell of a lot of intelligent life in the Universe and since the Universe is over 12 Billion years old, then surly Aliens have visited earth or are hear already, it's all probability.
