The discussion revolves around the speed of gamma rays and whether their higher energy allows them to travel faster than the speed of light (c). Participants explore theoretical implications and models related to the speed of light and energy of photons.
Participants express differing views on whether gamma rays can exceed the speed of light, with some asserting they travel at c while others propose theoretical models that suggest otherwise. The discussion remains unresolved.
The discussion includes speculative theories that challenge established physics, such as DSR and loop quantum gravity, which may not have consensus support. The implications of these theories on the speed of light and energy relationships are not fully explored or agreed upon.
This works by the fact DSR allows the energy of the photons themselves to in fact alter the speed of the photon. Blue light, for example, would travel at a slightly faster speed than red light. This difference is of course minute. Maguijo reasons that in the early universe, where photons had much higher energies than today, their velocities may in fact be significantly higher. Though this is in direct contradiction of Einstein, it does solve a lot of problems in cosmology.
