There is no place in the universe that doesn't have something in it. At least photons of some wavelength. The ultimate background is at a temperature of 3 above absolute zero, so that (microwaves) is always there. It's not much, really, but it is definitely not nothing.

Again, though, doesn't that beg the question as to what exists OUTSIDE of the known universe? Is there nothing SOMEWHERE? Is it possible? (Somewhat serious question)
