comment The Momentum Operator in QM
@Tony No, it doesn't. Applying the momentum operator to the wavefunction is equivalent, as shown above, to taking the gradient and then multiplying by $ \hbar \over i $. There is still a momentum that you can measure - but that is an eigenvalue of the momentum operator.

comment Has the speed of light changed over time?
@lurscher Why do you think it is more valid to say that the speed of light changed, rather than the wavelength of the sodium line, or the half-life of the ammonia resonance? I could choose to try to measure the wavelength of said sodium line using light, and conclude that it varied, not the speed of light. I don't agree with your point.

comment Why is Neutron Heavier than Proton?
Well, you're right that we haven't observed it, but it would be very hard to make sense of the asymmetry of matter and anti-matter if protons don't decay (since that would imply baryon number is conserved).

comment Is it possible to build an instrument which can travel faster than light?
Also, note that neutrinos do not travel faster than light. There was a measurement error at CERN, a loose cable.
