You can't talk about 'beyond our universe' because our universe pretty much covers everything there is. Shut up woman, get on my horse.

Scraby · #**122** 01-03-2011, 06:55 PM

well,if it covers everything why is it not infinite? or is it infinite in a non infinite way........AGH my head hurts from this..... sometimes this can really land hard on yer head....

universe |ˈyoōnəˌvərs|
noun ( the universe)
all existing matter and space considered as a whole[...]

The universe would contain said "infinity".

The amount of matter in the universe is not infinite, so it does not need to be infinite in size. What aren't you getting?

scrabface · #**125** 01-04-2011, 04:18 AM

this is absolutely illogical. if there is infinite space, there must be an infinite amount of matter as there is an infinite high possibility. it's impossible for us to understand infinity (like Karl Pilkington), all I can imagine is a big big big biiig space and there always comes more, so a finite amount of matter in an infinite space doesn't make any sense. that's why I believe, that space cannot be infinite.

space outside of universe probably doesnt have anything thats why it is space,probably vacum or something,.... i have nothing to think of more

There is no space outside of the universe. The universe is all there is. It includes all matter, all dark matter, all energy and all the space (in terms of physical dimensions) that exists.

I think that before you post in here again, you should read the book 'The Universe: A Biography' by John Gribbin. It will explain these concepts (and much more) to you.

ugh,what would happen if someone exits the universe or passess trough the barrier or something,what happens to that spaceship

No there mustn't. The universe started with a finite amount of energy, and therefore matter, and will continue with those same reserves for its entire existence.

Oh, and the universe isn't technically infinite. It's just expanding faster than anything could get to the edge.

Scraby · #**131** 01-04-2011, 07:27 AM

if we travel faster than light would that help? (just asking)

ODDWORLDisTHEbest! · #**132** 01-04-2011, 07:43 AM

i think i can conclude, space (everything, matter or no), is infinite, the universe (the matter that exists in space), is not infinite, but is part of space, though it would be incredibly difficult, you can exit the universe, but space, (black), can not be exited as it exists everywhere, and is everything.

If you're trying to escape the universe, it's anybody's guess. But there's no 'if' - we can't, we never will, nothing made of matter can. Also some shit about infinite mass and relativity.

exactly, we would burst into atoms.

I thought 'before' the Big Bang, space and time didn't 'exist' and it was concentrated to an infinite number of 'space'. ... I can see it's totally useless to try explaining this bullshit. impossible! everything I know loses it's meaning when I start thinking about infinity. it's so dumb, that we try to explain each other the nature of infinity and prove it's existence with ... words.

ODDWORLDisTHEbest! · #**136** 01-04-2011, 08:40 AM

before the big bang, space existed, so did matter, if matter didnt exist, then what created the big bang? the universe didnt exist, only a tiny bit off matter formed the big bang, all the rest was just darkness.

It's good that Professor OddworldistheBest is here to clear these things up for us. Thanks, Professor!

There are a number of hypotheses regarding the topology of the universe, each depends on assumptions that we lack the capacity to substantiate, due either to technological restraints or the basic impossibility of particular observations. Based on what I've read of them, and I don't even understand most (read: all) of the hyperdimensional mathematics, everything everyone has posted here is completely wrong, excpet for Nate who is almost comepletely wrong.

One of my favourites in the zero-energy universe, in which the sum total of all the energy of the universe is precisely zero, which neatly wraps up quite alot of problems about where is came from.

Anyway, here is a punctured torus beging turned inside-out.

Don't ask, I cannot answer.

T-nex · #**139** 01-04-2011, 09:12 AM

I wonder what it would take for us to develop a brain advanced enough to understand these concepts fully X_x

We can get out when the Universe slows down in expansion which should happen as would any explosion or reactions blast radius...we could throw robots at the edge too.

There was nothing that exploded and turned into the precise equivalent of nothing whilst actually being quite a lot of thing.

Genius!

Sort of. The energy represented by matter, energy and inflation precisely cancel out the negative gravitational energy, but only providing that the topology of the universe is flat.

We do actually see something from nothing all the time. Basic quantum uncertainty energy fluctuations in the fabric of vacuum itself sponaneously produce particles such as electrons and their anti-particles (positrons). But they must be dissappear rapidly. The gravity of a black hole can separate these pairs, preventing their annihilation, by capturing one of the pairs. But the mass of the the other particles is ultimately provided by the black hole itself, so over time black holes "evaporate" into nothing.

Oh I wasn't poking holes, I just think it's funny.

STM · #**146** 01-04-2011, 12:10 PM

Anyone watch that space programme that was just on BBC with that physics bloke and Dara O'Brian. They actually had a picture of Andromeda with all it's black holes, new stars, systems and clouds of gas!

Scraby · #**147** 01-04-2011, 12:13 PM

no but im gonna now,sice it includes something far away!

That looks like some kind of super-vagina.

Superior.

Since when was a tesseract superior to a vagina?

actually I dont think the universe will slow down because of it being in space, an object in motion will stay in motion untill hit by an unbalenced force, on earth that force would be gravity, friction or an obstical in its path, as there would be nothing in the universes path, no gravity to speak of and as it is not rubbing against something there is no friction, so I think it will just keep going at the same speed, the only way I can think of to get as fast or faster than it would be to somehow recreate the big bang and find a way to survive, or if we could get close to the speed of light and figure out how to slow down the entire universe so that the time that passes outside would be the same time that passes inside than inter steller travel might be possable, although close to the speed of light might be enough, time is slowed down by gravity right? so when we leave our star the universe around us would be quicker, so both our destination and point of origin would be slower than us and thus cancling out the time dialation effect, it may not work as I have no Idea how much our suns gravity is slowing time. and yes I do watch too much docter who
