In physics and especialy quantum physics everything is theoretical. It may well be that all our current theories are close approximations to reality, or we are COMPLETELY wrong and by complete coincidense we are mislead into believing their validity by close corespondense with observation, (chances of this are null).

We have the theory of relativity, not the law of relativity. We have the standard model of particle physics, not the "law of quantum interactions". All theories are mathematical models that happen to explain observations in nature to a great degree of accuracy. That was my mistake in saying they proved the Hawking Effect in that it hasn't been observed, but it had better be correct if our current theories and understanding of quantum physics and gravity are to hold any ground. This effect was proved on mathematical grounds, not observational. Negative energy is just as much a theoretical consequence of QED and GR as is energy. And what's more is whether or not virtual anti-particles can have negative energy rests simply on the definition of such particles. QED says you could very well interpret them as such.
