How long will it take for the cosmic microwave radiation to pass us?
Fascinating! Can the cosmic microwave background radiation tell us anything about the early universe?
Absolutely! The cosmic microwave background radiation provides us with a snapshot of the universe when it was just 380,000 years old. It has allowed us to measure the density and composition of matter in the universe, and has provided evidence for the theory of cosmic inflation, which explains why the universe is so homogeneous and isotropic on large scales.
