Study Notes

The Big Bang Theory

The initial state of the universe was extremely hot and dense, with temperatures and densities that are difficult to imagine.

Cosmic Microwave Background (CMB) Radiation

The CMB radiation represents the residual heat from the initial explosion of the Big Bang, which is the oldest light in the universe.
The CMB radiation is invisible to the naked eye because it is in the form of low-energy microwaves, which are not visible to human eyes.
The temperature of the CMB radiation is approximately 2.725 degrees Kelvin, which is extremely close to absolute zero.

The Expansion of the Universe

The Big Bang theory predicts that the universe is still expanding, with all matter moving away from each other.
The expansion of the universe is accelerating, with the most distant galaxies moving away from us at the fastest rates.
