[SOLVED] Space: Is it a place? Or is it a physical entity?
Space is nothing more than an empty room. From reading some threads I get the impression that some people believe that space, or spacetime, is a physical construct that can have effect on the motion of bodies. But the reality is that space is just a place in which physical things reside. In the area that is space there are countless objects, by our limited calculability, but each and every one of them has their place in space the same way that a chair takes up space in an empty room. This placement is true for stars, or galaxies, or any of the fields that such matter produces.
From our perspective, the universe seems unlimited. No matter the strength of our newest telescopes, we have found no perimeter to the material placement of the objects in space. But there must be a peripheral area, an outer boundary, where the physical objects in space border the empty space beyond. In that empty space beyond there will be no gravity or any other type of field because there will be no physical matter to generate any kind of field. This determines that the universe we live in is a finite, organized construct, no different than a galaxy except for size and the arrangement of the mass within it.
