What is beyond space and where does is end?
The space (or more precisely the “Universe”) has NO end (no boundaries). We are not sure of its shape, because we do not yet know for sure how many dimensions there are. So… To visualise space with our poor perceptions of a curved universe, imagine a balloon. This is the Universe. Mark dots on the balloon: these are stars, planets or galaxies. The hard thing to conceive is that we are only THE SURFACE OF THE BALLOON, and there is NOTHING INSIDE, nor OUTSIDE. The only thing that exists is the skin of the balloon. It is not contained in anything. So, as you move around the balloon, you will never reach an end. There are no “ends” on the surface of a sphere… Once you understand that, the mysteries disappear…
