How is it possible for space to be never-ending but how is it possible for space to stop?

Answer 1

Well most physicists will tell you no. They theorise that the universe is ever expanding due to the big bang thus it having an end at some point. However there are many other less known theories that the Universe is of infinte space. The real answer is we dont know.

Answer 2

To be honest, no body can ever know for sure if it is infinite or not.

The two most common ideas are that the universe and space do have a end but also "expand" into the nothingness where there is no time, no space, so the universe is constantly growing and can go on growing forever.

The other idea is that space and time is shaped like a "horn", think of it as the universe being on the surface of a big sphere, like earth, if you flew in one direction for a very very very long time you would eventually end back up where you started.

The following post belongs to someone different than the one above.

I contend to say that the idea that space has an end is a weak minded assumption. Although eternity is a hard thing for a human being to grasp (this is why we have so many "physical" opinions on space) I find it settles the mind better to conclude that space is eternal. There is no beginning, there is no end, it has no shape or boundaries, it does not expand nor detract, it just IS. To look at eternity all you have to do is look up at night.

Answer 3

As our Universe expands, it is creating "space" as it expands. Therefore it is NOT expanding into anything.
