What is dynamical expansion and thermal history of the Universe?

Dynamical expansion of the Universe is the expansion of space, caused by the Big Bang, which allows galaxies and other cosmic structures to move farther away from each other.

Thermal history of the Universe refers to how the temperature of the Universe has changed over time as a result of physical processes.

The Big Bang is an example of a physical process that has had an effect on the thermal history of the Universe, as it is the event that set off the expansion of space and caused an increase in temperature.

The cooling of matter due to radiation is another physical process that has had an effect on the thermal history of the Universe, as it causes the temperature of the Universe to decrease over time.

The formation of galaxies and other cosmic structures can also have an effect on the thermal history of the Universe, as the formation of matter can cause an increase in temperature.

Dark energy is another physical process that has had an effect on the thermal history of the Universe, as it causes the expansion of space to accelerate and can result in an increase in temperature.

The formation of stars is another physical process that has had an effect on the thermal history of the Universe, as the energy released
