I teach physics at Fullerton College, a community college in Southern California. I have an undergrad degree in math and physics from Berkeley and a PhD in physics from Yale. Back when I was doing research, my field was experimental low-energy nuclear physics.

comment Why Negative Energy States are Bad
This is total nonsense. The definitions proposed here are not even viable definitions, because they don't handle the zero-mass case. The relativistic relation that works for all masses, including zero mass, is $m^2=E^2-p^2$, which is perfectly compatible with $E<0$. If this elementary classical argument had been correct, then it would have been a schoolboy mistake for Dirac to propose his picture of the Dirac sea.

comment How come some people are claiming that the Big Bang never happened?
This doesn't address the question.
