Question

Does outter space really go on and on forever? and how is that possible??

Answer 1

Infinity can be a hard thing to grasp,same in math.

Answer 2

just think how big space is that we know of....

i'd find it a whole lot easier to believe space just expands in every direction infinitely, then it is to believe we live in a giant bubble.

Answer 3

Think "infinite nothingness" (Lao Tzu, IIRC)

Really, what is so difficult about imagining that empty space isn't SOMETHING, but rather that it's NOTHING?  And therefore doesn't have to be somewhere, or bounded by something.    Infinitely nothing.

Answer 4

Scientists for one thing certainly don't know if space goes on forever and ever. But there is such a thing as Deep Space.

From seeing pictures, we can't tell just by looking if space

is like how it is in Star Wars.

This is an important and unanswered question in cosmology. Space might go on forever (flat universe), or it might curve back on itself, so if you travel far enough (in a straight line), eventually you get back to where you started. Which would kinda be a little scary. Lol.

But then again, you never know. It could go on forever and ever, a million years into the future or past; But there would be a wall that just stops and starts all over again.

As u know, space is nothing (besides stars) space is ever expanding but does has a end. before your at the end, lets say 10000 feet away , your in nothing. When you're at the end, the other side is nothing and the space side is nothing. When you pass the end, theres nothing. so simply, if you take the nothing away from space then on the other side would be nothing.

Answer 5

It is a theory. It can not be disproved until someone finds and end to it.

Answer 6

we don't truly know but we do know the universe is still expanding at this point

Answer 7

The problem is that we can only know about things we can see, and our best telescopes can see about 18 billion light years. For now, thats about how far it appears that matter in the universe goes on.  What comes after that?  We can't know because light from there hasn't gotten here yet.  It could be more matter, it could be nothingness.  We don't know yet, but more light from farther and farther away gets here every day, and we learn more as it comes in.

Answer 8

no, it ends... somewhere... i think...? weird...

Answer 9

Some people propose that the universe is oscillating and expands and contracts and never loses energy so though it may be finite in a way it is infinite

Answer 10

We don't know that, but if space ended, what would be on the other side?  More space?.

Answer 11

It ends at what we call the 3rd Heaven...

Answer 12

No, the universe does not go on forever, in fact nothing does.  There is good evidence that the universe is expanding, if it were infinite, then how could it get bigger?

There is no edge or end though, not in 3-dimensional space plus time.  Like the anology to the earth's surface, you can walk all the way around it, but you will not find an edge to jump off of the surface of the earth.  (a cliff maybe, but that's different, you still fall to the surface)

Answer 13

You are obviously new to this section and astronomy. So I will lay it out simply. It all started with the Big Bang. That was when the universe was condensed into the size of an atom then exploded in a huge fireball. What was left was gas and dust. Now here is the thing. Everything expanded. Like a baloon being inflated. So the entire universe was condensed into an atom, then it all expanded, and so did space. One question everyone asks is what did the universe expand into? No one knows. So anyway, once it exploded it started to expand and hasn't slowed down in 13-14 billion years! This expansion is called the Hubble Constant. So there technically is a limit to the universe it is about 93 billion light years across. Here is the wikipedia article that will help:

Here is the important part of it though:

Since special relativity states that matter cannot exceed the speed of light, in a fixed space-time, it may seem paradoxical that two galaxies can be separated by 93 billion light years in 13 billion years; however, this separation is a natural consequence of general relativity. Stated simply, space can expand with no intrinsic limit on its rate; thus, two galaxies can separate more quickly than the speed of light if the space between them grows.

So technically, there is a limit. Pretty cool huh? If you liked this, check out this website: http://www.astronomycast.com/

It has podcasts about the big bang and tons of other astronomy stuff. You can even download it right to your ipod or MP3.

Answer 14

I think it does go forver even though thats hard to imagine

Answer 15

I asked my science teacher the same thing and she said we do not know because we don't have enough technology and gas to fly there to see if we do have any limits.

Answer 16

because of god

Answer 17

No personally I think we live in a universe with limits.
