Where can I find a place where space does not exist to do some scientific experiments?

LOL :D

Three cheers for creative thinking outside the box

but I think you may have an impossible logical conundrum there.

My knowledge of physics is not good enough.

Have you read Steven Hawking's "A Brief History of Time."

I would say it's the best starting place to look for a possible answer to your question.

I've read a couple of Mr. Hawking's books. Rather difficult to grasp but it is interesting material.

You can test this theory and many others like it at the Restaurant at the End of the Universe.  To get there you'll need a towel, a probability drive, a babelfish...

I wait for the movies. :-)

Hmm.. ok.

In science fiction. Go into s black hole in a spaceship. Go through a wormhole where space does not exist into another dimension, which there is space. If you saw the movie "Interstellar", they did this. Cool movie.

I better check it out.

Oh -it's a science fiction documentary.

LOL!  Not exactly.  Ever hear of Hitchhiker's Guide to the Galaxy?

Everybody conveniently forgets about the singularity. :-)

Yeah I 'll have to give it a read.

"Restaurant at the End of the Universe" is the sequel. :-)

Imagine living on the surface of that balloon, as some kind of tiny creature that lives only on the surface of the balloon. You can only see in the 2 dimensional surface; you cannot see or move off the surface either towards the center or outwards away from the center. Our universe is like that, but with one extra spatial dimension.

You can google 'fifth dimension discovered'. Quora has some interesting material.

Sorry can't make a link using my cell.

What I'm getting at is that your condition of "no-space" in which to blow up a balloon is mistaken and nonsensical. Maybe you meant it as a joke, I don't know. But blowing up a balloon in 3 dimensional space is already a perfect analogy, if you can imagine that 2 dimensional beings could live on the surface. The analogy is not that the balloon represents the universe, with us 3 dimensional beings living inside the balloon, with "nothingness" all around. That would make no sense. The only thing the actual universe could be "expanding into" would be a 4th spatial dimension (don't confuse this with the 4th dimension being time; that's an outdated and kind of misleading idea) that us 3 dimensional beings don't have access to, just like the 2 dimensional beings living on the surface of the balloon don't have any access to the interior or exterior of the balloon.

Ok. I did make the question in the 'outside the mug' category.

I do learn stuff sometimes by asking nonsense questions.
