Originally posted by bjpcomethmm, space definitely exists, because it is something, nothingness, which is something different, well given that you can define it as the absence of something, then does that mean it is something? Which seems contradictory... but the question was can it exist. I would say gut feeling, yes, there is such a thing as nothingness, therefore it does exist. But that's just me.
Does space (nothingness) exist?
things can move through it so it must, but it consists of nothingness, so can it exist?
Does a coordinate system exist without a graph in it?
Even if you look inte the perfect vacuum with 'microscope' at quant level, you'll see a lot of things and activity. Particles spontanous being born and disappear after a picosecond. Energy level rise and set. And a lot of things. There is a lot of energy, vacuum energy, that just sit there ready to be tapped by any technological civilisation advanced enough 8which we are not yet9.
So space with vaccum is not empty, it exists alright.
Even if you want to assume the perfect vacuum with absolute nothingness, it will exist. Escher used to make a nice example where the white objects would only exist with the black objects. You needed both in order to see either. Therefore complete vacuum still exists, because without it we wouldn't have non-vacuum and vice versa.
