A few things.
It is possible to have particles that can only travel faster than light (they are called tachyons). I haven't heard of any experimental investigations into the existence of tachyons (but there probably are some constraints).
Usually when scientists talk about time travel it...
A particular photon would redshift because it loses energy as it propogates. It initially started deep in a gravitational potential well (at the time of the big bang). The total energy of the photon is conserved, so as it escapes the well, it loses a portion of the energy corresponding to its...
Feynman used the "positron is an electron that goes back in time" idea quite a bit. I'm not a fan of that interpretation. He has a book called QED that would talk some about it, but I don't recall him putting forth a one electron model.
I would propose that there are more than one electron...
The decision should depend somewhat on how far you intend to go, the most imporant school is the last one you attend. You don't want to go to an undergraduate school that will mess up your desire or aptitude for graduate school. MIT has a reputation as a good undergraduate program, I haven't...
non outsourced jobs
I haven't been able to read everything that has been posted so this may have been stated already. But... Jobs for defence contractors and other federally funded research labs cannot be outsourced because they typically involve a security clearance. So companies like L-3...
