Let me start by saying that I'm just a layman afficionado to physics.
As I understand, most physicists believe that fundamentally, all what fills up the universe (all kinds of matter particles and all forces) must be different configurations of some unique "fundamental energy", and that at sufficiently high energies everything would merge into some single "entity". The different configurations we observe happened when symetries got broken by the cooling of the universe.
It seems to me that among what we observe in the universe, there is a quite radical separation between matter and radiation. The most obvious difference being that radiation stayed massless and thefore fills the universe "at the speed of light", which in turn determines a completely different interaction with space and time as compared to matter.
What is it that actually differentiates radiation from matter? just the fact of not having acquired rest mass?
Was there a definite symmetry breaking which defined the fate of the fundamental energy to become either matter or radiation?
If so, why did some energy turn into matter and some other into radiation, and not all energy into one or the other?
Sorry if I'm too naive ...
