TOPIC 1: The Big Bang Theory - MATTER ERA

Matter Era

After the explosion, the universe was finally able to fuse protons and neutrons, the matter era started to take place. This era is defined by the presence and predominance of matter in the universe.

Matter Era

This era also contains epochs which spans billions of years, the vast majority of the universe’s life span, and the present day.

Atomic Epoch Temperature & Time

Temperature: 3 000 Kelvin Time after Big Bang: 50, 000 years

Atomic Epoch

In this epoch, the universe’s temperature has cooled down enough for electrons to attach to nuclei for the first time which the process is called recombination. Through this, the universe’s second element was formed, Hydrogen (H).

Galactic Epoch Time After Big Bang

200, 000, 000 years

Galactic Epoch

During this time. Hydrogen along with Helium atoms, dotted the universe with atomic clouds. Within the clouds, small pockets of gas may have had enough gravity to cause atoms to collect. These became the seedlings of the formation of galaxies.

Stellar Epoch Time After Big Bang

3 billion years

Stellar Epoch

This is the present and current epoch that the universe is at. Stars began forming inside the galaxies. The creation of stars caused a tremendous ripple effect and helped shaped the universe as we know it.

Stellar Epoch

Heat within the stars caused the conversion of Helium and Hydrogen into almost all the remaining elements in the universe. These elements became building blocks for planets, moons, life, and everything we see today
