if space is always expanding,what is it expanding into?

Answer 1

It's expanding into superdimensional hyperspace.

Answer 2

Of course, Remember 9-1-1 and Spaceguy are right, the universe expands into nothing, as such. Our problem is; we are wired to understand what we need to survive as an intelligent animal. Anything beyond that is hard to grasp. Consider this: Where is the origin of the big bang in the sky? The answer is: everywhere, because everywhere we look at the sky, we see the past. That's right: when you see the sun, you see the sun where it was 8 minutes ago, and the further you see, the further in the past you see. In fact we see not in 3 but 4 dimensions, time included. If you want then to make a drawing of how the universe expands, you can't because your drawing will only be a 2 dimensions perspective of 3 dimensions. To illustrate this, imagine we remove one space dimension. Then, with only 2 space and 1 time dimension, we can visualize the universe as a sphere where everything is on its surface. As the sphere expands, we observe that each point on the surface is moving away from us. That's the red shift of the far away galaxies. But since we are now 2-dimensional beings, we can't see nor imagine the actual 'outside' of our sphere. It simply doesn't exist and that is what our universe expands into.

Answer 3

The mass and total energy of the universe are fixed, but the galaxies are moving away from each other. Therefore the universe is expanding.

Cosmologists have described space as being finite but boundless.

It can therefore expand and get bigger without having an 'edge' or needing to have an 'outside' to expand into.

Us normal mortals find this difficult to visualise with our 3-dimensional brains, but those are the facts nevertheless!

Answer 4

For my tuppence worth -Space is not expanding, space never ends, but the matter within space is expanding further apart

Answer 5

Space is not expanding but the universe is. Thus one must assume that space is infinite but the universe is not.

Answer 6

No one knows the answer to that, The only universe we know is what we can see and we cant see beyond it all, Just a wild shot in the dark though it may be just the black vacum of emty space where nothing is or was,

Answer 7

Theoretically, it is expanding into nothing. Don't try to understand it! Even Stephen Hawking couldn't explain it to you, or me for that matter, if you will pardon the pun!

Answer 8

space doesn't expand

Answer 9

The universe might be a big balloon in a bunch of balloons and when this universe has expanded so much it might pop. WE'RE ALL GONNA DIE!!!!!!

Answer 10

The final Frontier.
