Space is room so that physical things can manifest and therefore exist . From the thread in Astronomy , Exobiology and Cosmology
Well.... photons - energy - compacts to make physical things. The idea of space being a fabric has long been discouraged as a helpful analogy, beyond the basic level.
then i think "if i want to taste that bit in the middle, and stick my spoon in, will it still be the same?"
And is absolutely needed for anything to manifest in a physical state . From the subatomic , to galaxies and planets etc .
The title. The fact that it's asked in a forum. We might assume the poster has not found the basic answers out there to be satisfactory, so he's asking for more. [ EDIT ] nm. I just realized who the OP is. And the fact that no elucidating questions were asked in post #1. Thanks for drawing my attention to that.
