My concept of reality is one of a huge infinitely entangled mind of connected concepts, which is basically energy and information rather than matter that is mostly empty space. Actually, there is no such things as "empty space": no matter where you place a receiver, it will always be able to tune into some frequency to receive information. This not only works for technology, but for human beings as well. Put me in a totally dark room and I may not be able to see anything, but I can still hear.
Coming back to the "no empty space" idea, science has now largely proven that even in the intense vacuum of space, there is a tremendous amount of energy. Nassim Haramein even concluded that we can explain the reality without the strong force, as that is just gravity at an atomic scale.
