Every star is confirmed to have a planet around it. If there are 400 billion planets, 2/3rd or so are earth-sized, 1 in 10 are terrestrial , so 27 billion terrestrial planets. Why does he multiply it? sorry i'm a bit confused. Shouldn't he be dividing it? :S and imho the guesses he makes (like 1/2nd of terrestrial planets have life) are a bit off...
@MrNotoriousNinja And yes these factors are mere "guesstimates". Carl never claimed it to be more than that. Remember, he did this tv show back in the 80s. These factors would be changed from what we know now (with the Hubble and all).
It hasn't even been a hundred years since we discovered that other galaxies existed and that they are in movement. The stars that we looked are but a few. We could be in an area of the galaxy considered "rural" to others or we could be overlooked as uninteresting or as an undeveloped race still prone to aggression. We also base the development a sentient race along our own conceptions. It all sums up that we still have much work to do and we need to get out in the stars to find out.
Just my opinion, but some intelligent life forms might still be just getting out of their equivalent of the Stone Age or the Iron Age. Maybe some are just now learning how to build the type of tools & devices for mass production. Maybe some species & civilizations didn't develop contentious religions like humans did.
Wow, the possibilities! Simply wonderful to marvel at. However, it seems the likelihood of us destroying ourselves is high (with people like "terrorists" around). I hope people get their stuff together and stop trying to destroy the world.
The Fermi Paradox & the Drake Equation are guesses & not even good guesses. Hopefully they inspire people to think about things but many come to unjustified conclusions.
@Strangerinasland There is a difference between a guess and an estimation. For example, my step father was a sailor and asked me how high I thought a bridge 2 miles away was. I asked him how high the mast of a typical sail boat is (similar to ours). I projected that distance into an imaginary perspective line and counted by an estimated 10 units (for speed purposes). I came within 10 feet of the actual hight.
A guess is 'heads or tails'? - where you have no basis for an answer, just a gut feel
@Strangerinasland The Drake Equation is exact, it is not in the slightest bit a guess.
The values we enter into it, some are guesses, some are exact measurements. However the ones that are guesses we can give very reasonable guesses and even with incredibly conservative guesses that we are almost sure are guessing much too low, still give life being certain.
as soon as travelling space brings commercial intresst even the dumbest f**k will agree on spending human resources and material on the subject. but untill then we will cut nasa funding and spend 1000 times more money on porn than on keeping humanity alive by spreading into space. way to go humanity, way to go *clap, clap*
The special thing about the earth is that it has a large sister planet (the moon) . Life probably evolved on the tidal shoreline accelerated by evaporation, heating & whatever of the primodial 'soup'. It has also helped to stabilise the seasons. This might mean life is a rare thing or it might mean we have had a head start.
Wow, sometimes i like to read comments to get a general idea of each layman's view. Recently, i can't help feeling like I'm living in the movie titled "idiocracy":
An "average American" is selected by the Pentagon to be the guinea pig for a secret hibernation program. Forgotten, he awakes 500 years in the future and discovers a society so incredibly dumbed-down that he's easily the most intelligent person alive..Seems we need to add an f(d), the fraction of planets that are "dumbed-down"
Don't forget he is just talking about our galaxy. There are over 100 billion galaxies in the observable Universe. If an advanced Alien species does exist than I believe they found a way around the speed of light barrier, not by physically going faster, but maybe using a device that can bend two distant objects closer together.
Basically any advanced Alien species that survived billions of years would be Gods to us. I mean we would literally not know the difference. Their technology would not even be comprehensible to us. They could already be here and we just can't see them. They could be pure digital forms.
The sad thing about drake's equation it that it calculates the number of civs posibly existing not the posibility of us meeting with them; which would extend the equation by more fractions reducing the N way too much even if it is in the Mega scale. Also we should consider factors for even when 2 civs can meet whether one or both actually want to/should/cannot meet reducing N even more. Then again there are dimentions and the like so it gets back up again! Oh well its too complex to calculate.
The problem, of course, is that none of the terms can be known, and most cannot even be estimated. The only way to work the equation is to fill in with guesses. As a result, the Drake equation can have any value from "billions and billions" to zero. An expression that can mean anything means nothing. Speaking precisely, the Drake equation is literally meaningless...
i think he is too optimistic about the amount of habitable planets per system and where life evolves. there are so many systems with planets that aren't habitable that it should be a decimal at least, and forming life also requires a set of more extreme prerequisites. And i don't think there will be 100 million civilizations nuking themselves to death, but that's just my opinion. i'd say there'll bee about 10'000, but given the size of the universe we'll neve be able to contact them.
@Subject134127 .....planets that aren't habitable....can you back that up?......what if there are 98% habitable planetesimoids or moons,,,,then you are a heretic...a liar....you say nay....I say yay....
@johnsmdm I am merely a realist, I don't say you lie if 98% of planets are habitable, but i say that it is highly unlikely. Seeing there is only 1 habitable planet (and here i mean without spacesuits or anything, anything you can normally live on) in our solarsystem of 9 planets, it would be 11.1% already. if you then look at how many stars actually have planets and how many of THOSE are habitable, you'd sadly get a very pessimistic number.
@smithistheownage incorrect by whom's definition? numbers are concepts. you don't understand the concept of something, nothing and everything. you only accept what is taught in grade school.
You say I don't understand the concept of something, nothing and everything. Perhaps not. Perhaps no one can really fully understand at least the concept of everything. But one thing is sure, I understand these concepts more fully than yourself. Thank you for assuming that I merely believe these things because they were told to me in grade school, its not naive of you 'tall. It happens that I'm currently enrolled in several demanding courses, including AP Physics and AP AB Calculus
and in these courses complex math concepts are fully taught and the theories are fully explained and the evidence is offered for such concepts as x/0= undefined and infinity(0)=0. These are things of which mathematicians have come to a consensus on after centuries of rigorous mathematic exploration. Not to say that I would accept the ideas without first coming to a full understanding myself, but this does seem to suggest which course of belief is more applicable to reality.
@smithistheownage think about the meaning of something divided by nothing. in two's complement binary arithmetic, when you try to divide a number by zero, you get an overflow error. this is because it is trying to infinitely carry the 1 to the next bit. it is undefined in math. it isn't shown to mean anything. math is whatever you define it to be. it is left undefined because there isn't much usefulness in defining the operation. binary arithmetic does suggest that it does equal infinity.
if it was infinity, then it would be defined as infinity in mathematics. Mathematicians have no problem grasping concepts of infinity. Imagine division by zero this way: Division by any number implies that that number goes into the numerator some 'x' amount of times. If we begin this operation with zero we see that by adding one zero to another we've gotten no closer to our numerator. So we continue to add zeros, but find it makes no difference. So, even after adding
an INFINITE number of zeros to our denominator we find that we are still in the SAME EXACT position, with x/0. Undefined simply means it can't be done. You're partially right about math being what you want it to be, in that humans created the concept. This is why humans like you also overcomplicate it. Zero is our concept of nothing, and numbers are our concept of SOMETHING. You cannot divide something by nothing. Any 1 given object doesnt have infinite nothings in it.
You blew my mind with this! Not the likelihood of other similarly intelligent forms of life (that's already a given), but the badass simplicity in the reasoning behind it. Scientific reasoning FTW!
@Aarownd That idea in itself shows the probability that we aren't alone. If we are a coincidence, what are the chances we're the only coincidence? The odds are astronomically low that something such as life (especially as far as we've gotten) would only happen once in the entire universe.
@GraveHorizon What are the chances? who knows! ooh! spooky! but it is possible that we could be the only for of life in the universe, it's arrogant to say that we even have a concept of how life came into existence.
@Aarownd Sorry to disappoint you, but we already have a concept for that. And it is possible that we are alone in this universe, it's just extremely unlikely. (Note the difference between unlikely and zero.)
@Aarownd Proteins and shit, the building blocks of life (as we know it). Chemicals combine and form stuff, eventually forming other stuff. Something weird like that. Or maybe a pool of ooze was struck by a bolt lightning, starting a chain reaction. Any process that gradually occurred over a considerable period of time, not dependent on something else magically wishing it into existence.
@GraveHorizon That's as scientific as saying it's because shredder dropped the ooze, and it got on some sea-monkeys, which caused them to evolve into monsters that fucked some monkeys, and made humans, science.
@sooparsoup kind of sounds right because you just need to be the right amount of distance away from the star, but suitable for life also means highly unlikely that life will even exist. look at venus and mars, they are also very suitable for life but because mars has little to no atmosphere and venus has to much atmosphere, life will most likely never exist on those planets
this video is garbage. Can't take a model and use random inputs for a reasonable output. Just six numbers govern the shape, size, and texture of our universe. If their values were only fractionally different, we would not exist
@GoodGodStopThis Did you even watch the video? 2:07 Before you start acting like a condescending little cunt how about you make sure you know what you are talking about
@GoodGodStopThis Whatever man. I just think that you should find better things to do than go around correcting peoples grammar on youtube all day. I fucking hate people like that, you didn't contribute anything about the video or somebody's comment at all you just acted like a little prick and corrected someone's grammar without submitting a comment of your own
if anyone would even come to this asshole planet, he/it would most likely it would be killed in matter of minutes. We can't even live among our own people and races, we keep destroying our own civilizations.. and now we think we would come in contact with something out there.. lol yea right /
@cyfer911 If visitors from another civilization were capable of traveling to this planet, we'd be the equivalent of amoebas to them. They'd have no reason to fear anything that we could do; that's how advanced they'd have to be just to make a trip of that nature.
that equation really narrows it down lol. But at least people now can say "theoretically life must exist" rather than "i done seen me sum spacemen, with theyre darn anal probing" Also, Carl sagan ftw
that equasion has changed slightly at the time that this was filmed as he said humans had only been sophisticated enough to possibly communicate with "aliens" for 30 years. that number has probably doubled since then. if anyone knows when this was filmed please let me know :)
@ThePostRockProject The equation has not changed at all "Drake's Equation" is the same now as it was when first postulated. What has changed is our understanding of the values that can be put in to the equation; ie, number of starts in our solar system, the fact that there are extra-solar planets (over 700 to date), availability of water in our own solar system an therefore the likely hood of life.
We are a long way from solving Drake's Equation, but it is a fixed equation.
As had the priests of science (knowledge) who'd preached and sermonized from their pulpits, during the reign of Caesars, about sacred linkages betwixt simians & humans (sans evidential relics); and beneficial mutations; and about the randomness of all systemic interactions: His Holy Eminence Bishop of futility and defeatism, the Pastor Carl Sagan, also waxed religiously & intimately of things that occurred billions & billions & billion of years before his birth beneath a pool table.
Wait wait ahahaha god did it ahahahahahaha..wheres my bible so i can gleen all the answers...who kid gets murdered by his dad...where do i go to kill my mouthy child ahahahahahahaha LOLreligiouspeopleLOL
There are so many astronomical events (like 1 in a trillion or smaller) that had to happen for us humans to evolve (I could list dozens and I'm not even educated on the subject aside from various articles n videos that I've read/watched,) that some scientists believe that perhaps the Universe isn't meant to support life, but that we hit the universal jackpot of real estate as well time period. I think there are probably only a few civilizations as impressive as ours out there.
@Marzano15 I meant to say that they think the Universe isn't meant to support complex and intelligent life like us. I'm sure there are trillions of planets that manage to crank out some amino acids here n there or amoebas, but too many conditions that aren't in place or that don't last long enough like here on Earth keep it from ever prospering as miraculously as we have. I hate how people say we are insignificant... We're the only things in the Universe that we know of that are self aware.
We are only aware of carbon life, but that doesnt mean its the only possible life.
For a long time we assumed the sun or stellar light was needed for life, this was proven false with the discovery of deep-sea organisms independently surviving from chemical processes using planetary heat.
Carbon is capable 4 million organic compounds, silicon only reaches about one hundred thousand anorganic compounds. Silicon is only capable of long chained molecules at the low temperature of -200c . Which prohibits life in itself as we know. At -200c chemical processes have also slowed down massively.
And last but not least , silicon likes to react with oxygen and i think you know what that means.
The problem with Drake equation is that it only considers FOUR dimensions, the same dimensions we are living right now. According to String Theory, there are at least ELEVEN DIMENSIONS, so that ecuation has very limited application.
@acuaman42 Of course the equation is for our third dimension, its about the posibility of life in this universe, i dont doubt that there is life in other dimensions but we cant proove that, but we can proove life in this universe by looking at ourselves.
there MUST be other planets with life beyond our own capabilities to know or reach them that is the way god intended it to be so we cannot contact each other worlds because we are all spaced so far apart hmmmm interesting theory but maybe thats the way the boss wants it to be?? live in our own little worlds only?
The equation has to be altered. Scientists found out that only systems with a very big planet like Jupiter (acting as a "magnet" for space debris) and a class m planet with a very big moon (much bigger than normal, made out of the planet itself though an accident) can bring out life in higher forms like mammals. The probability of that combination might be as small as 1/100000.
Add that to the drake equation and you find out that we presumably are the only intelligent race in the milky way.
@Strassenflirt yes but there are hundreds of billions of galaxys and im not saying well ever meet them but still also what about all the none intelligent life out there
Im satisfied with just finding life on other planets with no intelligence...i like how he also says its convervative to think there is about 100 billion planets with un-intelligent life =]
I really hope our species gets its act together. As Sagan says, we have only lasted technologically around lets say 100 years and look at how much damage we have brought to the Earth. That is a fraction of a second in the Universal clock - there is a hump we have to get over to last hundreds of thousands of years, lets just hope we make it to that hump so we can truly explore the galaxy.
Look at us...Humanity. How unlikely would it be that we are the only intelligent lifeforms that have technological abilities whithin the entirety of the Cosmos ? Astronomically impossible would be my guesstimate.
Rehashed ( lol ) Look at us...Humanity. How likely would it be that we are the only intelligent lifeforms that have technological abilities within the entirety of the Cosmos ? It is astronomically impossible, would be my guesstimate.
... of life makes it rarement by at least milions of milions times. So it would not be N=10 but N=1/100.000.000.000 in our galaxy, so only few in whole universe.
@VermilioNXYZ I can barely understand what you're trying to say, but the protein molecules that make up life on Earth are rather common.
As far as only a few in the universe... There's an estimated like 20 BILLION galaxies in the KNOWN universe. At just a couple hundred billion stars per galaxy... we're talking about planets in the 10^5000000th power! I'm sure SOME of 'em have life.....
@imthejman85 We know for sure that there is over 100 billion galaxys, an average estimate is around 200-300 billion and sometimes more. There coud be as many galaxys as there are stars in this galaxy, and we estimate that around 400 billion. Perhaps we are alone in this galaxy, but multiply the odds 3-4 hundred billion times and we get another picture for the hole univers. Add on that the multi-vers theory, shi* like M-theory and the like and you got a recipe for a headache. We are just a spec!
@VermilioNXYZ at the moment, we can't travel not even to the closest planet in our solar system, let alone to another star, LET ALONE TO ANOTHER GALAXY :) but maybe, in the future, we will be able to do that. or other civilization will do that and find US. :)
1st at f[l], number of life should be calculated by how many compounds from all known makes a life. So this could be one of bilionth (I am not biologist, I don't know how many exactly). So this is not 1/2.
2nd. at f[i], number representing a probability of existance of intelligent life should be calculated by how many species are in whole Earth (milions or more), and put that in denominator, (1 in numerator).
Only by these two mistakes it makes a probability of existance..
@VermilioNXYZ it's just a probability. for example in our solar system that number is 2. our earth and mars. because it's known that mars had an ocean at least for a few hundreds million years, which most likely harbored simple organic life :P
@VermilioNXYZ compounds are made up of elements normally created in stars and present in every planet. The elements spontaneously form all the compounds together in the conditions of suitable planets The componds that form life are not rare at all, there are even organic molecules on meteors. Also, from evolution, naturally millions of lifeforms on other planets would also exist, so multiply the probability of intelligent lifeform by the number of lifeforms, it becomes neutral
@pdiz ice age killed all life? wtf? aren't you and another 40 million species on this planet still alive after the ice age which ended 10.000 years ago? go back to school kid. you definatly need it.
This comment has received too many negative votesshow
Drakes equation is such a crock! Almost every rock anywhere in space has some kind of life on it!Look at earth its a tiny little planet at the ass end of the universe and its covered in life!How can these people make up such hogwash!They just want the general public down, not up and out!

@GraveHorizon What's your concept for how life came into existence?
Aarownd 1 year ago
@Aarownd Proteins and shit, the building blocks of life (as we know it). Chemicals combine and form stuff, eventually forming other stuff. Something weird like that. Or maybe a pool of ooze was struck by a bolt lightning, starting a chain reaction. Any process that gradually occurred over a considerable period of time, not dependent on something else magically wishing it into existence.
GraveHorizon 1 year ago
@GraveHorizon That's as scientific as saying it's because shredder dropped the ooze, and it got on some sea-monkeys, which caused them to evolve into monsters that fucked some monkeys, and made humans, science.

@sooparsoup kind of sounds right because you just need to be the right amount of distance away from the star, but suitable for life also means highly unlikely that life will even exist. look at venus and mars, they are also very suitable for life but because mars has little to no atmosphere and venus has to much atmosphere, life will most likely never exist on those planets

@ThePostRockProject The equation has not changed at all "Drake's Equation" is the same now as it was when first postulated. What has changed is our understanding of the values that can be put in to the equation; ie, number of starts in our solar system, the fact that there are extra-solar planets (over 700 to date), availability of water in our own solar system an therefore the likely hood of life.
We are a long way from solving Drake's Equation, but it is a fixed equation.

@Richiehurtsalot That is only partly correct.
Carbon is capable 4 million organic compounds, silicon only reaches about one hundred thousand anorganic compounds. Silicon is only capable of long chained molecules at the low temperature of -200c . Which prohibits life in itself as we know. At -200c chemical processes have also slowed down massively.
And last but not least , silicon likes to react with oxygen and i think you know what that means.

assassin611983 1 year ago
The equation has to be altered. Scientists found out that only systems with a very big planet like Jupiter (acting as a "magnet" for space debris) and a class m planet with a very big moon (much bigger than normal, made out of the planet itself though an accident) can bring out life in higher forms like mammals. The probability of that combination might be as small as 1/100000.
Add that to the drake equation and you find out that we presumably are the only intelligent race in the milky way.

Perhaps we are alone in this galaxy, but multiply the odds 3-4 hundred billion times and we get another picture for the hole univers.

He made a mistakes.
1st at f[l], number of life should be calculated by how many compounds from all known makes a life. So this could be one of bilionth (I am not biologist, I don't know how many exactly). So this is not 1/2.
2nd. at f[i], number representing a probability of existance of intelligent life should be calculated by how many species are in whole Earth (milions or more), and put that in denominator, (1 in numerator).
Only by these two mistakes it makes a probability of existance..
VermilioNXYZ 1 year ago
@VermilioNXYZ it's just a probability. for example in our solar system that number is 2. our earth and mars. because it's known that mars had an ocean at least for a few hundreds million years, which most likely harbored simple organic life :P
ChronicMist 1 year ago
@VermilioNXYZ compounds are made up of elements normally created in stars and present in every planet. The elements spontaneously form all the compounds together in the conditions of suitable planets The componds that form life are not rare at all, there are even organic molecules on meteors. Also, from evolution, naturally millions of lifeforms on other planets would also exist, so multiply the probability of intelligent lifeform by the number of lifeforms, it becomes neutral
