They obtain an effective mass phenomenologically by interaction. At high energies/temperatures that mass term becomes irrelevant. One can argue in reverse that we are simply at such a high temperature that the mass of the photon doesn't matter and that other effective interactions will dominate in what we would call an ultra-cold later-era universe. The inhabitants of that era will look at us as their inflationary phase. It's simple, elegant... and probably completely false. I like it anyway. | |

| Jun 17, 2023 at 1:04 | comment | added | FlatterMann | Or are we? CCC takes the lemons of a lonely ending and makes the lemonade of a brand new universe out of it with a fairly trivial and appealing rescaling argument that gels perfectly with one of the other grand questions of physics: "What in nature sets scale?". If the answer is "Nothing.", then CCC sounds like a home run to me that kills a large number of flies at once. | |
