Space — Gregory
Space is also inherently continuous (inside), just as it captures all reality in its hands (outside). The community of all points forms finite spatial objects but space itself is only continuous by being differentiated by its points, which are nothing. Space and continuous mean the same thing to me. All space is infinitely dense, so maybe space naturally expands — Gregory
Outer space, commonly shortened to space, is the expanse that exists beyond Earth and its atmosphere and between celestial bodies. Outer space is not completely empty—it is a hard vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium, as well as electromagnetic radiation, magnetic fields, neutrinos, dust, and cosmic rays
Is not the only thing conceivable as physically existing something that is spatial? — Gregory
It seems most natural to me to think of space as infinite. — Gregory
There is no end to how small something can shrink. — Gregory
In 2D and higher dimensions, space is less problematic as the boundaries of any given area/volume are not points but either lines/faces. — TheMadFool
There is no space as a place; the quantum fields exhaust reality. — PoeticUniverse
It is also my understanding that the universe is hypothesized to be granular at a sub-sub-sub-sub atomic level. The planck length, 1.616255(18)×10−35 m, — T Clark

It is also my understanding that the universe is hypothesized to be granular at a sub-sub-sub-sub atomic level. The planck length, 1.616255(18)×10−35 m, is considered by some to be the smallest meaningful dimension of space. — T Clark
There is indeed a combination of physical constants (h, c, and G) that gives rise to that lengthscale but that doesn't mean space is not continuous beneath that scales. — Cartuna
That's the case according to loop quantum gravity. According to general relativity and string theory it's continuous. — Michael
That's popular science, which is maybe the best suited for this forum. — Cartuna
Does Space actually exists? I mean out of human experience that we understand it, does it actually exist "on its own"? Or it's only an a priori human non empirical thing which allows us to form all of our experiences as Kant suggested? — dimosthenis9
I'd define space as that which everything moves through. — Gregory
Space and infinity are some of my favorite ideas, and they seem to naturally go together when we consider the universe. If there were a limit to the universe we could go to the edge and point, asking "how far is that way?" It seems most natural to me to think of space as infinite. And actually it seems to be infinite in opposite infinite ways. There is no end to how small something can shrink. And if I hop towards a limit, there are always infinite sub-steps. So infinity as space seems to be the ground of everything and "what is finite itself" adds form to the chaos. In the end, the world will always seem paradoxical because it has a paradoxically at it's root. What I'd like to know is whether space existing in all possible place is just the mirror image of space being infinitely divisible — Gregory
