When one attempts to understand REALITY it seems it eventually ends up connected to quantum mechanics. I do not think this is should be a factor when we are taking about a quark-based reality that exists at the temperatures, speeds and pressures found in the earth's biosphere where life exists. What happens at the core of the sun is a 'different' reality than what any human will ever experience. Likewise, what happens at the speed of light will never be experienced by any human. I agree that photons are very necessary components of our existence, but how photons behave has very little to do with the reality we experience at the very low velocity at which we exist. Anyone care to comment?
