Era of recombination - temperature variant

Click For Summary
SUMMARY

The discussion focuses on the era of recombination, which occurred approximately 300,000 years after the Big Bang, when radiation was first emitted in the visible spectrum. This phenomenon indicates that the temperature of the early universe was relatively constant during this period. The participants explore the implications of this constant temperature and the reasons behind the observed decrease in temperature over time.

PREREQUISITES
  • Understanding of cosmology and the Big Bang theory
  • Familiarity with the concept of the era of recombination
  • Knowledge of thermal radiation and its properties
  • Basic grasp of the visible spectrum in physics
NEXT STEPS
  • Research the implications of the cosmic microwave background radiation
  • Study the physics of thermal equilibrium in the early universe
  • Explore the relationship between temperature and radiation in cosmological models
  • Learn about the evolution of the universe post-recombination
USEFUL FOR

Astronomers, physicists, and students of cosmology interested in the early universe and the fundamental principles of radiation and temperature dynamics.

Homework Statement


When radiatio was first emmited 300,000 years after the big bang during the so-called era of recombination, it was in the visible region of the spectrum. What does this data tell scientist about the temperature variant of the early universe


Homework Equations





The Attempt at a Solution



well aparently the temperature remained pretty much constant, but how do you tell that?

why is the temperature constant? The temperature decreased!
