Do two photons emitted from two atoms 1 meter apart have a higher probability of being found further apart after one second? Is this an arrow of time?
Does relativity suggest that two photons emitted in close proximity will be found further apart over time, implying increasing entropy & time’s arrow?
The photon moves at the speed of light. In that case the mass of the moving photon is infinite according to Einstein's theory of relativity. Does that mean that photons warp space time infinitely? Could quantum mechanics emerge from general relativity? Can a photon be at rest or does it have to travel at the speed of light? If you have two photons with equal wavelengths and one has a bigger amplitude, what would that mean, would the photon have more energy? Do photons interact with other photons? Is it plausible that it's impossible to combine general relativity with quantum mechanics? If a ray of light looped in to perfectly reflecting mirrors from two sides facing each other, will light keep travelling in this loop forever? I think this is a very stupid question: in the reference frame of a photon, aren't we moving at the speed of light or faster? Can gravity bend space-time so that the path of a light beam from two points is shortened? Why we say "Photons travel with the speed of light", when it depends on the wavelength of the photon? Since information cannot be transported faster then the speed of light, isn't Einstein's "spooky action at a distance" solution more correct then "quantum entanglement"? If a photon travels at the speed of light and time dilation at the speed of light is infinite, does this mean that, from the photon's perspective, it takes no time at all to cross the entire universe? Is there any particle that could travel faster than a photon? If photons don't travel through time, why does it still take time for them to reach our eyes? Does time exist for a photon? If Larmor-Fitzgerald alterations of space and objects within it occur, could it be that time is regular after all, & relativity is explained by these? Does light travel through space forever? Could light be refracted into a loop, to be amplified or stored as a source of potential energy? If we could travel faster than the speed of light, would time travel backwards? Does entropy always increase at the same rate? Since light doesn't have rest mass but has energy, so if huge amount of light is accumulated at a point in space, will it warp space-time? If quantum entanglement is true then would it not be faster than light and hence violating Einstein's theory? Could the speed of light be increasing/decreasing? Where does the energy from photons affected by the expansion of the universe go? Quantum theory says a particle can be anywhere in the universe in the next instant.  Photons are the fastest particle but are limited to the speed of light. How can both be true? Will the speed of light ever change? What is the velocity of a photon attracted to singularity? Is the quantum entanglement effect faster than the speed of light? Does it take any time for photons to be released or absorbed, or does it happen instantaneously? Are gravitational waves just light speed ripples in space/time?
