Does it ever end?

Question

does space ever end? do you think that there is another diminsion? are there other planets that we don't know about? Plz anserw

Answer 1

If space has an ending, we cannot ever reach it, because it's expanding away from us at the speed of light.

Are there more then our usual four dimensions (3 spatial, 1 temporal)? If there are, they have not proven to be important in any way so far.

Are there other planets that we don't know about? There are almost certainly billions or trillions of planets we have not yet discovered.

Answer 2

I don't know if space ends - I doubt that anyone knows. It may depend on what you mean by "space." Do you mean empty space, or 3 dimensional space?

As for multiple dimensions: possibly. There are some interesting theories about the universe having multiple dimensions.

As for planets, the answer is most assuredly yes. Given that we have discovered more than 200 planets around other star systems, it seems very likely that there are others that we don't know about yet.

Answer 3

Space is infinite, and the probability in the existence of other dimensions is high according to mathematical models. Are there other planets that we do not know of? Yes!

Answer 4

since the technology doesn't exist for us to go to the edge of the universe, then I would have to say, no, it never ends. and there are lots of other planets out there, with people on them , wondering the same question.

Answer 5

Personally, I think that like trillions and trillions of lightyears away, there could me this border that separates us from a parallel universe. It sounds crazy, but who knows?

Answer 6

We are told that it is endless. Sure there are other planets. More are always being discovered.

Answer 7

after our universe there might be other universes too.
