This is something that's come up a few times now, and I'm not completely clear about it.
Is it correct to say that something being "physical", in scientific terms, is the same as saying it "exists"? Are these two terms exactly the same? I refer to literal existence, rather than abstract concepts which may or may not represent literally existent things.
If these two terms are not interchangeable, could someone please explain to me what the difference is? My first concern would be with "space", as in the space that is available for things to "exist in". Is the space itself physical? Does the space, or the potential it represents, "exist"?
Many thanks!
