Philosophy of Mind.

[NOBLE]

I don't know enough about physics to corroborate or argue against that. I look at it more from a philosophical point of view. But it seems the fourth dimensional space time crystals are still theoretical at this point. Has anyone ever produced one?
I don't think objects warping time and space means time and space are physical, but rather that time and space are/behave relative to physical objects.
I'm sure all this is based on real observations but many ideas in Physics are counter-intuitive to me.
For example, the whole universe/time/space expanding thing. If the universe is all that there is, then what is it expanding in?
I can blow air into and expand a balloon, but it only expands because it is in a space that is much bigger.
Does not the concept of the universe expanding suggest that there is something other than and outside the universe?
