SUMMARY

The discussion centers on the fate of energy resulting from matter and anti-matter annihilation in the early universe. It is established that for every billion annihilations, one atom remained, leading to a significant release of energy. This energy is now identified as the cosmic microwave background (CMB), which is a remnant of the early universe's conditions. The CMB serves as a crucial piece of evidence for the Big Bang theory and the evolution of the universe.

PREREQUISITES
  • Understanding of matter and anti-matter interactions
  • Familiarity with the concept of annihilation in physics
  • Knowledge of the Big Bang theory
  • Basic grasp of cosmic microwave background radiation
NEXT STEPS
  • Research the properties and significance of cosmic microwave background radiation
  • Explore the implications of matter and anti-matter annihilation in cosmology
  • Study the Big Bang nucleosynthesis process
  • Investigate current theories regarding the early universe's conditions
USEFUL FOR

Astronomers, physicists, cosmologists, and anyone interested in the fundamental processes of the universe's formation and evolution.

I've read how in the early early universe, there were massive amounts of collisions between matter and anti-matter, about a billion of each annihilated to every atom left over.
My question is, what happened to all that energy?

Without going into a lot of detail, it is the cosmic microwave background.
