It could also be that we merely perceive nothing when actually it is something only it's invisible to the typical perception.

I don't believe there is any such thing as what you would think of as "nothing". The universe is really just a sea of energy. The illusion is separation. Binding energies like light exist sparsely between spaces but exist they do. In this way all matter-energy in the universe is experienced as a gigantic wave of energy composed of many smaller and smaller waves of energy, some of which we perceive and some of which we don't.
