Is space infinite?

[NekoChan]

I thought the video was an awful representation. I'm pretty sure that you can't just fly outside the universe to a different one in 3D space. I don't think there would be navigable space between universes, merely emptiness in our infinite bubble. Of course, that theory relies on the existence of a 4th spacial dimension which is extremely difficult to comprehend naturally.

You can't, unless you are Professor Paradox my friend
