This is the idea of a “test theory”. If you are going to test a hypothesis (photon is massless) then you cannot use a theory that...

If I shoot a bullet at you, but do it while travelling away from you at several hundred meters per second, you can just catch the bullet...

What about energy

No mass is needed in GR - it's a theory of curved spacetime and particles in free fall follow geodesics (the generalisation of straight...

That's a matter of definition. In modern physics (last few decades, mostly), when we say "mass" we mean the invariant mass (a.k.a rest...

This is not surprising. You must know at least that in general relativity, gravitational potentials change the passage of time, so a...

Aharonov has been a favorite since at least 2009, now he is 94

I would love that one, because … well, Aharonov and his academic lineage deserve it :smile:

I believe that starfractal refers to Nathan Cohen and his fractal invisibility cloak. For a recent summary see: Scientist-Inventor...

which Cohen?

Pendry, Smith an Alu are being touted as potential Nobel Prize winners based, in no small part, on the alleged metamaterial invention of...

Well it is the right approximation of GR for the problems you are dealing with.

Just for the fun, yesterday there was the Ig Nobel awards. For physics we have: Randy Hurd, Zhao Pan, Tadd Truscott, Kaveeshan...
