The age of the universe can be calculated by :  dark energy, the age of the oldest stars patterns of background radiation, and the speed of distant galaxies moving away from the Earth.

Anything that acts as a container for energy and matter is known as the universe. The modern definition of the universe is the place that has time itself including the other heavenly entities like Comets, meteors, Stars, Planets, and many more.

The age of the universe is determined by scientists using the following ways:

  • Concept of dark energy is the property of space and it is used to predict the age of the universe as this form of energy is observed to expand the universe rapidly.
  • The age of the oldest star patterns of background radiation is another way to determine the age of the universe as the first generation of stars are formed after the big bang.
  • As per the Hubble's relation, the galaxies move away from the Earth at a certain speed are proportional to their distance. In other words, galaxies are farther as they are moving away from the Earth.

Thus, we can conclude that the age of the universe can be calculated by dark energy, the age of the oldest stars patterns of background radiation, and the speed of distant galaxies moving away from the Earth.
