From a little understanding or misunderstanding of it from GR, the gravitational effects don't arise from  the massless photon being attracted gravitationally to a star or planet. It is said a massive object warps the shape of space time around it. The photon, following a straight path at the speed of light, is just traveling along the curvature of space created by the massive body. Without our ...

Shekib: Can one send a message using 2 particles that are entangled ? Only one bit of info. The next bit would require a new set of particles. This is because when you detect the pair's state, you glean the info and de-entangle the pair.

Well classically it is not required that the electron be a point particle in fact a simple google search will yield Lorentz's prediction of the electron's radius which is about 1/1000 of a Bohr radius. Its one of those questions that is reasonably interesting to ponder but currently all measurements seem to suggest that it is a point particle. I am not sure but no current theories rely on the ...

Well spin really has no classical analog. There is no physical situation I can point you to to illustrate the concept because spin is Completely Quantized and the states are Completely Discrete. Essentially it has to do with the intrinsic angular momentum which is related to a magnetic moment of the electron. If you shoot a beam of atoms or electrons in a constant transverse magnetic field they ...

You hit the nail on the head with the mass thing. A massless object requires no force to accelerate it to lightspeed. In fact, lightspeed is the only speed a massless object can exist at.

"nothing" makes more sense if described as a state of zero entropy - a highly unstable state; and skip the "Black Hole" reference, if anything a White hole. Other than that your description parallels the various quantum fluctuation theories. Neat "twist of logic" on the "symmetry of nothingness"

kinda supports that light isn't the only thing that travels fast as light. i know that a shadow is the depletion of light, but can a shadow be cast as fast as light?

Robert: Just to shore up the basics before I ask the main question on my mind; It is said that light travels (C) "in a vacuum", and is said to travel slower through various other media only because it interacts with atoms in media, causing a chain reaction in the atom which culminates in the emission of a photon onward- The reaction then takes longer than it would take the light to travel ...

But then, these two processes could theoretically be 99.999% or so energy efficient. That would allow this to occur with very, very little exhaust. But then, the object would be losing mass-energy, not gaining it, since the source of energy was within the object itself, not its surrounding. Not to mention, it would lose mass-energy in the form of gravity, as all objects do.
