I was riding home from school today and just started to think about if there was other life out there, and I told myself "of course there is" because the universe goes on forever, but that was what made me get a chill. I started to think about galaxies, planets, and stars. It just feels weird to think about it. How the universe goes on forever, it just doesn't make since. Do you guys think that there is other life out there? Do you ever wonder about other galaxies? Discuss.
I rly think theirs another form of life somewhere in the universe... but as you say sometimes when i think about it and those stars and planets wtv... and as you say again that it goes on forever and us we are there in the middle of no-where , its kinda scary/strange....
But i think this question will never have an answer but im sure somewhere in the universe theirs another type of life, or just the same type of human as us.... and they are thinking: '' fuck is there another type of life somewhere ? ''

The idea that the universe 'goes on for ever' is only one possible theory.
It could be infinite or it could be finite.
It could have boundaries or it could be boundless.
But either way, it's bloody huge, and there's a stupidly large number of galaxies, solar systems and planets out there. So the chances of there being life out there somewhere are really quite high.

Statistically speaking, life must exist on other planets, there's no way our planet is the only one out of the trillions that can support life.
I doubt we'll ever meet the aliens though, faster than light travel seems to be impossible.

I wish we had the technology to go as fast as light years. It would be amazing to see what other life is out there and what they look like, and all the planets that probably have different minerals, elements, etc.
resists erge to point to multiple threads on this subject
Ya sure, definately life out there.
Ya sure, definately life out there.
When you think about it, Us human are so small, we are nothing, just bunch of no where form of life making our rules and killing our self.....
Universe is infinite.... and i hope we could travel fkn fast and go out there and see

well according to the Hitchhikers guide to the Galaxy the population of the universe is Zero.S.Lythberg wrote:

It is know that there are infinite number of worlds, simply because there is an infinite amount of space for them to be in. However, not every one of them is inhabited. Therefor, There must be a finite number of inhabited worlds. Any finite number divided by infinty is as near to nothing as makes no odds, so the average population of all planets in the universe can be said to be zero. From this it follows that the population of the whole Universe is also zero, and that any people you may meet from time to time are merely the products of a deranged imagination.
So if space is infinite as in infinitly big, doesn't that mean it also has to be infinitly small?
Well yeah... but what do you mean exactly?AudioAtomica wrote:

yeah, i know, even a percentage of infinity is still infinity, but it's still a good quote !AudioAtomica wrote:

The universe is not infinite, it just may as well be.Andoura wrote:

To imagine the universe going on forever is hard to wrap your mind around. I think perhaps if you travel in one direction after leaving the Earth, hundreds of light years later you'll end up right back where you started. Just a theory.

Ok Einstien ! " imagine the universe going on forever is hard to wrap your mind around." but a universe that is somehow warped so that if you go in a straight line in one direction you travel in a cirlce is less hard to wrap you head around !BeerzGod wrote:

I'm not sure, exactly. 'Small' and 'big' have nothing to do with the infinite. It's like asking if zero is brown as well as green...unless he's suggesting that big = small, in which case I'd still have to say that these adjectives alone have very little to do with immeasurability.Spark wrote:

Off topic, anybody know of a good solution to get the smell of paint thinner out of your nose? I've been around the stuff all day.

actually zero tastes more like purple
What I meant was, people are saying the univverse is infinite, and what they mean is it's so LARGE it goes on forever and ever, but in order for it to be infinite, it has to go both ways, I.E. infiity doesn't just go 1,2,3 it goes 1,2,3 and -1,-2,-3 at the same time, so if the universe is 'inifnity' big then it's equally small aswell...right?
So it can't be infinite, it has boundaries.

I know what you're trying to say and, well, we just don't know, not with 100% certaintity. And it depends on who you ask as to which answer you'll get about whether the universe is either infinite or finite, or, bounded or boundless.AudioAtomica wrote:

I think an infinite universe makes more sense than a finite one. If it were finite, there would have to be a border. What would the border be? How could it be a normal substance? It would also have to go one forever. Otherwise, if it was ever pierced .... what would be beyond?thareaper254 wrote:

Well according to the Big Bang theory, the Universe suddenly began to expand very quickly, and still is expanding. Not to mention if we have boundaries, and seeing how galaxies themselves are flying through space (and occasionally collide ever few million/billion years, causeing mishapened galaxies) Then you would think a galaxies would collide with the border, but the only thig I can think that could be preventing that is if galaxies rotate on a axis, or rather the center of the universe, or perhaps the universe expands faster than galaxies move, preventing any collisions with the borders?confused wrote:

As I stated befroe if the universe is Infinite (As in large) then it has to also be inifnitly small, so it is NOT infinite, it has boundaries somewhere out there even if it's still expanding.
That's my two cents anyhow.
There are 3 possibilities:
1. The universe could be finite and bounded.
Basically think of a sheet of rubber - and the surface of the rubber as 2-dimensional universe - our universe could be like that - both finite and bounded - but in at least 4-dimensions (up/down, left/right, forwards/backwards, and time).
Now imagine drawing lots of galaxies all over the rubber sheet, then grab the sides of the sheet and pull - as the rubber stretches and expands, the galaxies fly apart, but so do the edges - so the galaxies never fly off the sheet.
2. The universe could be finite and boundless.
Take a ball. Imagine the 2-dimensional surface of the ball is a 2-dimensional universe - it is finite in area, but has no boundaries - which direction you move in, if you keep traveling in a straight line around the ball, you come back to the point you started at.
Now, don't try twisting your brain around imagining this - it's, well, virtually, impossible - apparantly some mathematicians can do it, but only after a career's worth of imagining higher-dimension topologies - but the universe could be structured like a ball - only a 'hyper-hyper-ball' - having at least 4dimensions, finite in volume, but with no boundaries.
Ok, now, again, imagine galaxies all over the surface of the ball - and then inflate the ball - again the space between the galaxies expands.
3. It could be infinite and boundless.
This one is pretty easy to imagine - the universe just goes on and on, infinite volume, no boundaries.
The slightly tricky bit comes when we think about the expansion of the universe - if it's infinite, how can it expand?
Well, think of it a little like this - every point of space, everywhere, is expanding, matter does not expand, but space does - the amount of space between the matter expands and so the galaxies fly apart.
It starts infinite, it remains infinite, it finishes inifinite. But everything's moved apart.
Again - don't try to imagine this - you'll only hurt your brain....

Slight problem there, ratios aren't inherently finite or infinite.buttersIRL wrote:

If one in a thousand planets has life it just means that we could go on checking planets forever, and would only find one with life for every thousand planets we checked. The number of inhabited and uninhabited worlds would both be infinitely larger, just we'd discover uninhabited worlds at a far greater rate than those which are inhabited.
