unconventional means of propulsion ?! They exist , For example Burkhard Heims Stardrive is most of all unconventional , And maybe it is 1 of the 5 mayor means 2 get humankind of this system .
Some scientists claim that we do have the technology to build 1 of B:H´s at present day , But it will be expensive.. However , it will also be cheap compared 2 some other brainstorm ideas .
Belive hes engine could take us to mars in under 3 hours . Google Burkhard Heim 4 more info ;)
@rabidsushi Yes that might be the only way to travel through space, unless we can find a way to travel beyond the speed of light. Well we broke the sound barrier and now can travel beyond the sound barrier. I suppose eventually we will brake the light barrier. I would give ourselves at least a 1000 years before we can do that.
Don't forget not only the distance & speed factors but also the time factor. It is calculated that if one traveled at the speed of light for 7 1/2 years they would age 7 and 1/2 years but for the people they left behind on earth he would have been gone 500 Years!
@unclejay1000 Well all things are possible given enough time. So yes space travel can be possible maybe 1000 years from now in the year 3000AD. Things take time. We are still taking our baby steps when it comes to science and technology.
Why is there always a nice round number? Who's to say we won't master interstellar travel in 200 years? When they invented airplanes some laughed at the idea that they could carry people over the Atlantic rather than ships, and yet in the 1930's it was already reality for paying passengers
It only took 44 years from the first flying in 1903 to the soundbarrier being broken in 1947
First man made object in space was Sputnik in 1957,just 12years later humans were walking on the Moon
@McLarenMercedes Yes things need time to evolve. When we put a man on mars is when we can start thinking of other planets. That could happen in maybe 200 years but for interstellar travel? Come on, that WILL take a 1000 years if youare looking at it from an evolutionary stand point. If we made some make some amazing discoveries in that field then you can maybe chop a couple of hundred years off. This kind of travel is the most difficult yet so thats why i give it a 1000 years.
Nonsense. If you travel at the speed of light for 7 and a half years you have been gone for 7 and a half years to the people on Earth. However a person travelling at that speed won't have aged a single second, and are still the same age when he returns, whereas all others have aged 7 and half years.
A lightyear is the distance light travels in a year. Hence you can't have been gone for 500 years if you only traveled at the speed of light for 7,5 years to the people left on Earth
:34 "for astronomers it does make a big difference that the speed of light travels at a finite speed" This is a true statement, it may not be true that light has always traveled at the same finite speed. This is an assumption that is commonly made because it gives them more certainty in their predictions.
to travel far distances of universe we have to make a ship which can travel in universe with speed of light.with this speed we can reach Uranus in just a week.
so.... is it possible that there is some sort of life form travelling to us at this moment, but is not visible because we are looking at some super old light? O.o
When I was 20 I knew intuitively that time is not part of space. It took me 32 years to understand rationally that according to mathematical formalism X4 = ict time is numerical order of photon motion in 4D space.
so we cannot see things further than 13 billion light years right? cause the universe is that age?, how can astronomers deduce the distance of the objects they are seeing? - da m so many questions
We cannot see things further than 13 billion light years away because light from farther away has not yet reached us (and perhaps never will).
Astronomers can estimate the distance of the objects they see using a principle named redshift, although it's just an example of the Doppler Effect, making and approximating such measurements is slightly more troublesome.. If you're really into it just google 'redshift physics'.
How did they know the other images places in the galaxy without visiting it,that is so far to get to their it takes lightyears and we not yet achieved as travel as speed of light.
They use telescopes for that. The light reaches us, that's the whole point. We discovered the speed of light in the 1760's already, and have just measure it more exact since then.
There's proven methods of how to measure distance in space by using the spectrometer os something.

and it would be very sad to know that there is a big probability that the solar system is the only system that exist st this time, all stars we see are from ancient times and now instantaneously they dont exist anymore.
All that stuff out there is so far away, if we ever got out to it, it would be gone by the time we get there. Its a big light show? Another thing puzzles me. Of all the different movements this way and that could it be that I am stationary and everything else is moving about? Yeah! I know its globalized thinking but what do I care?
@boilerplate7 Not sure what you mean "Of all the different movements this way and that could it be that I am stationary and everything else is moving about?"
From your frame of reference you are stationary. So to answer the question "could it be that I am stationary", the answer is yes, it can be, if you chose that frame of reference. There is no absolute frame of reference in the universe.
@w7y7a7t7t yep, 8 minutes into the past. now imagine if someone from a different planet with an ultra-powerful telescope was looking at Earth right now. They could be seeing dinosaurs!
If you look into a friend of yours right next to you, you are also looking into the past. We're talking 1 nanosecond ago. Which is ,000,000,001 seconds ago. That is in the past too.
And this woman is a woman with a telescope, im just predicting that she works alone. So she is and idiot cuz she did her math wrong. A light year is 6trillon miles. She is so stupid hahaha
No YOU are stupid, because she said 10 trillion KILOMETRES, which is the distance it travels.
Now, you have got to realize that they use kilometres all over the world. The only 3 countries in the entire world that don't use the metric system are Liberia, Burma and the USA. That's all.
You're either a troll or a genuine idiot who thinks he is smart. I'd say it's the latter.
@football4life1000 when physicists talk about speeds, they mean anything that carries energy. There are "things" that go faster than light (although thoughts aren't part of them...) but nothing carrying energy in any form can travel faster than the speed of light (in a vaccum). So your example is incorrect, but your idea is right
if something 100 light years away from us had a powerful enough telescope, they could watch the last 100 years of human history take place. Our past is out there playing live, somewheres in our galaxy.
yep, sad but true. probably another 100 years till we set foot on mars evan tho its been over 40 years since we apparently first set foot on the moon and no 1 has been back there yet
@deadlyvicar yes i dont believe we hav set foot on the moon bcoz we could and would have built bases there etc etc! ...if we grow plants up there,they would make there own oxygen and eventually make a atmosphere like on earth!
There are way more terrorists in Saudi Arabia, Pakistan, Aghanistan and Syria then they are in Iraq you ignorant fool. Wtf does "skumy" mean? Find that in a dictionary.
@DerEine0101 when you saying we?? us humans?? not before the year 3000AD man will discover time traveling. teleporting for place to place.. and even traveling to other galaxies and take over other planets. it is all possible for us humans..
@DerEine0101 David Sereda explains how it is possible thru raising the frequency of any mass. In one of his series he mentions a NASA astronaut invented a very advanced frequency pulse engine. we currently have the means to travel the stars, there are other inventors with actual patents of devices that can do it. But who is gonna experiment with it out there? Government agencies have craft that can do it but experiment with them very carefully & most likely not outside the atmosphere.
@lokey745 no we cant. I mean we could but wed b dead by the time we got there due to having no food or water. Also u hav to hav fuel to get back. We will eventually get there but not at the moment. May b anothr 10, 20 years.
@DerEine0101 yes we can and we have but not with humans and nasa is sending a spacecraft to pluto (or so i herd) but nasa is starting to try to plan and develop tec that allows few ppl to live there becous there is a gap each 2 years that earht and mars go the closest that we will send spacecraft and stuff like that if im mistaking then thats what i heard soory 4 bad spelling im from iceland :)
@DerEine0101 Yes, we can travel to Mars but if the question is, do we have enough food supplies to go and come back? We have to wait for another 500 years for the science to come up with a space ship that can travel at the speed of light or use a worm hole.
@DerEine0101 I agree. Just the technical challenges aside, We can get anywhere in the Solar System (it's money and decade of planning.) . Freeman Dyson calculated it would take 300 million years to explore the milky way using the 'Apollo-Era' rocket technology. Seems like the best way to explore deep space is by using more sophisticated satellite telescopes and robots.
@DerEine0101 Yes we can. It might take a couple of thousand years to do so but i think we can. Keep in mind that we have landed on the moon only 42 years ago.
Sure we can land on Mars. We have landed on Mars with spaceprobes several times. It's the least hostile planet after our own. Getting there is possible too. The problem is staying on Mars for over half a year until Earth is in the proper position (shortest way home from Mars) and then the way back home. The total trip would take almost a year, and how will a spacecraft have enough air, food and energy to last a whole year?
@DerEine0101 We will one day. At least we were lucky enough to survive the stone ages ect without an astroid taking us out. Luckily we can pretty confidently defend the Earth from such atrocities. From now on the technological gradient can only get steeper.
@DerEine0101 That is very ignorant, anything and everything can happen with time, that's a physics law itself by Newton. We have only been working on space and breached it for what hmm? 50years? Think about that. And yes sorry that this is a year old :P
Actually, the Andromeda Galaxy (so named because it appears within the constellation Andromeda) is 2.2 million light-years from our own. Traveling there at an apparent velocity very close to the speed of light could get you there in a couple years, because of Time dilation / Distance contraction. Some people believe that 4.4 million years will have passed on Earth during your relatively short voyage.
Do you read what you type? We can't if we can. Just face up to it. We can't. billions of dollars are wasted on research conducted by stupid morons while the economy and wars destroy us. Put that thinking and money into more prolific work rather than daydreaming idiots get paid taxpayers money.
mm studying is good but i think that the new world is fucked up with korrupt people and leaders.
we are just braking the chain of nature that humans are suposed to die and new humans suposed to live and the deeper we have went into the future we have done it worse with our greeds to overcome this chain who have given us light.

the universe is estimated to be 40 billion light years across but hubble's constant suggests that universe is 14 billion years old.
we know nothing can travel faster than light so how did the universe expand so large ??
in 14 billion years light would have moved 14 billion light years across obviously but if universie is 40 billion light years across universe must have expanded faster than the speed of light?? :S
But i´m not sure if you can compare the speed of light to the expansion of the universe. I mean we have no idea where the center of the universe is, and we do not know if it´s expanding inside something else or just out in...nothing
if universe is 14 billion years old then the maximum time the light could have possibly spent travelling is 14 billion years thus covering 14 billion light years distance at the speed of light!
if universe has expanded to 40 the ends surely must have done it faster :s
While special relativity constrains objects in the universe from moving faster than the speed of light with respect to each other, there is no such theoretical constraint when space itself is expanding. It is thus possible for two very distant objects to be moving away from each other at a speed greater than the speed of light (meaning that one cannot be observed from the other) The size of the observable universe could thus be smaller than the entire universe
that is not true...the universe began after the big bang explosion...
1. afta 1 sec...time strted
2. afta 1 min...light was created...
3. afta 1 billion yrs...galaxies, planets, stars r created...
after the explosion...the universe was never ending...the universe keeps expanding and will always be expanding....the speed of light has NOTHING to do with the expansion of the universe....it just keeps on growing and growing...just 2 add sumthin if u dunno, light only travels 30000km per sec....
the universe has no diameter...the universe neva ends...lets say if the universe was only from the sun to earth...IF...if u travel from the sun to earth and go on further...you will appear back to the sun...its that magical! so the universe has no diameter because it just never ends...wen sumthin hv a diameter it could also mean that u can actualli reach one end from another end
ALLS I KNOW IS nikola tesla made energy go faster than light 100 yrs ago with his wireless energy system! he made industrial energy fo 10 - 100 times faster than light! i even show this on my youtube site of teslas wireless energy system which is important to a future world! tesla was the first scientist to discover faster than light energy transfer now we reffer to it as quantum entaglement! tesla made the final model of the qunatum tunneling device 100 yrs ago!!!
guys just say we are going to the closest sun how many years will it take not light years actul years plz answer me.. and how far is the other side of the milky way as in years plllzzz i am so confused
well the milky frm the very point of one end, and u want to travel to the other end...it will take u 100,000 light years to get theree...but if u say u dont want to travel in light years...then i guess it will take you 1000000 years...not much jst added another zero
wait a second, the big bang only occurred 3.7 billion years ago(the universe's birth) so how does the light from the quasars arrive from 10 billion years
This comment has received too many negative votesshow
HOW ?? let me elaborate cunt .. 10 billion years ago i fucked your mum while masturbaiting over your dads beautiful fat cock i speremed like da speed of light u fucked SPEDTRONIC BITCH .. I dont know but tha light arrives in your asshole after i ejaculate and take my anaconda cock outta it, cyclying out to produce assbreath on my dick fart once im your friend fart twice i'll fuck your friend, penis is your best friend after matchsticks sucked on your ass cheeks like poo wafers in indian tea ABO
The Big Band occurred roughly 13.7 billion years ago, so quasars from 10 billion light-years ago are within scope of human sight. However, even things 30 billion light-years are possible to see, because there weren't always 30 billion light-years away. The universe used to be much smaller, it's been expanding ever since the Big Bang. We can see light from places 30 billion light-years away because light from them has only had to travel fewer than 13.7 billion light-years. Hope this helps!
might i ask a question then? if the equation e=mc^2 is "true" then that means nothing can travel at the speed of light, without requiring an infinite amount of energy. say the speed of light is 100 and the gravity of planet x is 7, then doesnt that make light travel faster? and yes, light has to have mass, otherwise it would be immovable, seeing as m/e?correct? so therefore if light travels through space, and the hits the gravity of planet x, doesnt light travel 107? making it expand?
How do they know how many light years a galaxy is from us? What actually measures that? Please don't call me an idiot or anything, I am new to physics...
You're an idiot! They send an astronout to the source of the light, give him a digital stop watch, have him set it at zero, and have him switch it on the moment he starts his journey back to earth. When he arrives, they look at the stop watch for the duration. Dah!
i know...but i'm replying back to a guy that said the way to tell the diameter of the milky way is determined by an astronaut travelling in light speeds...i was like...can an astronaut travel in light speeds though?
so let me get this str8 to look into the past on earth we should place a "mirror" at the end of our galaxy then when we look in that mirror we would see the past far back as it would take the light to travel to the mirror and back? woohoo now how do we get the mirror there so people in the future can see us BAM theres you time machine....well kind of lol but it makes sense right other than the tuff obsticle lol
If you were 65 million light years away and had a REALLY good telescope you could watch the comet hit the earth, killing all the Dinosaurs! That's a good way to explain to 2nd graders, light-years in a nutshell..
can someone explain something to me, if we see something happening on a star that is 1 lightyears away, then does that mean what were seeing actually happened billions fo years ago, it just took that long for the light from it to reach us? im a bit of an idiot when it comes to lightyears, as you can probably tell
Kinda. 1 light year is how far light travels in 1 year. Therefore if you look at something 1 light year away you are seeing what happened 1 year ago. If you look at something 50 million light years away you are seeing what happened 50 million years ago.
waiit ur comment is intersitng soo just say we want to go to the other side of the milky way how many years is that from us just say 100,000 light years so that is just still 100,000 normal years or wat am so confuseddd plzzzzzz
Well if you are going to travel from edge to edge of milky way how fast do you wanna go? Do you want to travel in a slow space ship or a fast one? Or perhaps you could find a worm hole and the whole trip would last 10 minutes on a bike. Space CAN warp and time is not constant so choose smartly.
Astronomers can only estimate at the size of the Milky Way. If you could travel at the speed of light it would take you 100,000 years from edge to edge.
if your looking at shit 10 billion years old, then whats the point in studying them? im sure they have expanded or transformed by now...BTW this old bitch explained "the speed of light" verry well to me.
I agree there may be flying aliens or sth and it will be possible to see what there is now will be available after 10 billion years :D
That's kinda the point. Being able to study things how they used to be is a good way to learn why things are the way they are now or how things might progress in the future.
They sure do. We need a space drive capable of working continuously at 1g. At that rate, the moon is 4 hours away (assuming you turn around halfway there!), the inner planets can be reached in a few days, and the outer planets in a few weeks. (Exact times depend upon the relative positions of Earth and the destination)
the distance between our sun and Proxima centauri actually about 4.23 light-years away. The fastest outward-bound spacecraft yet sent, Voyager 1, has covered 1/600th of a light-year in 30 years and is currently moving at 1/18,000th the speed of light. At this rate, a journey to Proxima Centauri would take 72,000 years.
So no way on today technology we can manage to do interstellar traveling, even thought we know there is a planet on other system that can actually support live.
In other word we stuck in our own solar system, that is until we found some technology that manage to get us at least 10% of light speed, or maybe some other method for vast distace traveling, like wormhole or Warped spacetime.
This comment has received too many negative votesshow
if your looking at shit 10 billion years old, then whats the point in studying them? im sure they have expanded or transformed by now...BTW this old bitch explained "the speed of light" verry well to me.
How do we know that the speed of sight is not capable of covering the distance from me to a star and preventing me from seeing the star as it is now and not waiting many light years for the light to get to my eye?
Because we know what the speed of light is. If you look at the sun, you're also not seeing it as it is right now. You're seeing how it was 8 minutes ago. Do you understand?
Truthfully you can only see the "reflection" of what these galaxies looked like 10 billion years ago. What they really are is "now" is very different, only you have to wait another 10 billion years.
If you could to travel @ c towards this reflected light than the present view of these galaxies would become clearer the closer you got to them.
She should have mentioned that something as distant as Andromeda is assumed to be is not actually measurable. Anything over about 120 light years is only estimated. We do not have any (accurate) method of measuring vast distances. Our current places of reference, which can be substantiated, leave us with a small ruler.
How then can we see Andromeda as it IS now; instead of what it appeared 2 million years ago?

All that stuff out there is so far away, if we ever got out to it, it would be gone by the time we get there. Its a big light show? Another thing puzzles me. Of all the different movements this way and that could it be that I am stationary and everything else is moving about? Yeah! I know its globalized thinking but what do I care?

@boilerplate7 Not sure what you mean "Of all the different movements this way and that could it be that I am stationary and everything else is moving about?"
From your frame of reference you are stationary. So to answer the question "could it be that I am stationary", the answer is yes, it can be, if you chose that frame of reference. There is no absolute frame of reference in the universe.

Sure we can land on Mars. We have landed on Mars with spaceprobes several times. It's the least hostile planet after our own. Getting there is possible too. The problem is staying on Mars for over half a year until Earth is in the proper position (shortest way home from Mars) and then the way back home. The total trip would take almost a year, and how will a spacecraft have enough air, food and energy to last a whole year?

Actually, the Andromeda Galaxy (so named because it appears within the constellation Andromeda) is 2.2 million light-years from our own. Traveling there at an apparent velocity very close to the speed of light could get you there in a couple years, because of Time dilation / Distance contraction. Some people believe that 4.4 million years will have passed on Earth during your relatively short voyage.

this is what i dont understand
the universe is estimated to be 40 billion light years across but hubble's constant suggests that universe is 14 billion years old.
we know nothing can travel faster than light so how did the universe expand so large ??
in 14 billion years light would have moved 14 billion light years across obviously but if universie is 40 billion light years across universe must have expanded faster than the speed of light?? :S
lookwhoscomin 2 years ago
woah! I was thinking about that too :O
It seems kinda of queer.
But i´m not sure if you can compare the speed of light to the expansion of the universe. I mean we have no idea where the center of the universe is, and we do not know if it´s expanding inside something else or just out in...nothing
ensittare 2 years ago
we can i cant explain it well but ill try
if universe is 14 billion years old then the maximum time the light could have possibly spent travelling is 14 billion years thus covering 14 billion light years distance at the speed of light!
if universe has expanded to 40 the ends surely must have done it faster :s
lookwhoscomin 2 years ago
i found this useful from wikipedia
While special relativity constrains objects in the universe from moving faster than the speed of light with respect to each other, there is no such theoretical constraint when space itself is expanding. It is thus possible for two very distant objects to be moving away from each other at a speed greater than the speed of light (meaning that one cannot be observed from the other) The size of the observable universe could thus be smaller than the entire universe

after the explosion...the universe was never ending...the universe keeps expanding and will always be expanding....the speed of light has NOTHING to do with the expansion of the universe....it just keeps on growing and growing...just 2 add sumthin if u dunno, light only travels 30000km per sec....
SOLAR718 2 years ago
the reason why speed of light is linked is because i was talking in light years.
one light year is the distance light travels in a year at the speed of light.
universe is 14 billion years old so the maximum possible diameter of the universe at the speed of light should be 28 billion light years.
all i was saying is how can the universe have a diameter of 40-50 billion light years when the universie isn't even that old
but now i know... so stop replying :|

the universe has no diameter...the universe neva ends...lets say if the universe was only from the sun to earth...IF...if u travel from the sun to earth and go on further...you will appear back to the sun...its that magical! so the universe has no diameter because it just never ends...wen sumthin hv a diameter it could also mean that u can actualli reach one end from another end

The Big Band occurred roughly 13.7 billion years ago, so quasars from 10 billion light-years ago are within scope of human sight. However, even things 30 billion light-years are possible to see, because there weren't always 30 billion light-years away. The universe used to be much smaller, it's been expanding ever since the Big Bang. We can see light from places 30 billion light-years away because light from them has only had to travel fewer than 13.7 billion light-years. Hope this helps!

might i ask a question then? if the equation e=mc^2 is "true" then that means nothing can travel at the speed of light, without requiring an infinite amount of energy. say the speed of light is 100 and the gravity of planet x is 7, then doesnt that make light travel faster? and yes, light has to have mass, otherwise it would be immovable, seeing as m/e?correct? so therefore if light travels through space, and the hits the gravity of planet x, doesnt light travel 107? making it expand?

Well if you are going to travel from edge to edge of milky way how fast do you wanna go? Do you want to travel in a slow space ship or a fast one? Or perhaps you could find a worm hole and the whole trip would last 10 minutes on a bike. Space CAN warp and time is not constant so choose smartly.
Astronomers can only estimate at the size of the Milky Way. If you could travel at the speed of light it would take you 100,000 years from edge to edge.

the distance between our sun and Proxima centauri actually about 4.23 light-years away. The fastest outward-bound spacecraft yet sent, Voyager 1, has covered 1/600th of a light-year in 30 years and is currently moving at 1/18,000th the speed of light. At this rate, a journey to Proxima Centauri would take 72,000 years.
So no way on today technology we can manage to do interstellar traveling, even thought we know there is a planet on other system that can actually support live.
