Is There a Third Thing?

There is no edge to the block, if you're thinking of cosmological sense. So it leads to a slightly different kind of interpretation. I've got enough energy in space time itself when you define it in this way as gravitons to cause gravity. And that's the main objective. But we don't need those other energies. We are not talking about some third thing. No, no, there is no third thing. Forget about the zero point fields,. all these other things because let's put it straight, Jim. The blast is thought experiment. As it leaves the block, a photon will return to its normal speed and the block will be brought to a stop.
