THE ENERGY OF EMPTY SPACE THAT ISN'T ZERO 
A Talk with Lawrence Krauss

We've got this weird antigravity in the universe, which is making the expansion of the universe accelerate. Now: if you plug in the equations of general relativity, the only thing that can 'anti-gravitate' is the energy of nothing. Now: this has been a problem in physics since I've been a graduate student. It was such a severe problem we never talked about it. When you apply quantum mechanics and special relativity, empty space inevitably has energy. The problem is, way too much energy. It has 120 orders of magnitude more energy than is contained in everything we see! more...
