Big Bang Model of the Universe
(1929)

The Big Bang Timeline
A. Inflationary Epoch
The universe continues to expand. it became distinct: gravity, strong nuclear fce and elctromagnetic force. By the first seconds, the universe is made up of fundamental particles and energy : quarks, electrons, photons, and neutrinos.
The Big Bang Timeline
B. Formation of the Universe
Protons, and neutrons combine to form hydrogen nucleic. Then hydrogen began to combine pairs to form helium nuclei. This process is called nucleosynthesis.
The Big Bang Timeline
C. Formation of Basic Elements (3 seconds)
Most of energy in the universe was in the form of raditation. These include different wavelengths of light, X-rays, radio waves and UV ways. They formed what is called the cosmic wave background radiation.
The Big Bang Timeline
D. Radiation era
Matter began to dominate and the end of radiation era at this stage, lithium atom began to formed. Electrons joined with hydrogen and helium nuclei to make scales neutral atoms.
The Big Bang Timeline
E. Matter domination
The slightly irregular areas of gas cloud, gravitatonal attract nearby matter and became denser. The dense gas clouds collapsed and eventually gain enough mass to ignite producing light. The huges gas cloud can be the birthplace of dozens of stars, The group of stars became the galaxies.
F. Birth of the Stars and Galaxies
