Theories of the Origin of the Universe

Ancient civilizations attributed the universe's formation to deities and mythological explanations.
Major religions like Islam, Judaism, and Christianity assert that a Supreme Being created the universe.
With advancements in science and technology, many began to support scientific theories over religious explanations.

Big Bang Theory

Proposed by Georges Lemaître in 1927, suggesting the universe began as a singularity containing all energy, space, and time.
Approximately 14 billion years ago, this singularity began to expand, releasing energy and resulting in the formation of matter.
Initially, the universe was in a hot, dense state where matter and energy interacted closely.
Fundamental forces arose during early universe expansion: gravity, electromagnetic force, and strong and weak nuclear forces.
These forces facilitated the formation of atoms, the basic building blocks of matter.
Nucleosynthesis is the process where forming atoms combine to create the first elements: hydrogen and helium.
Hydrogen and helium contributions led to the eventual formation of stars, galaxies, and other celestial bodies, including planets and comets.
The Big Bang theory is widely accepted due to its strong supporting evidence and alignment with observations of the universe.
Evidence includes the phenomenon of redshift, the increase in light wavelengths from distant galaxies, indicating they are moving away.
In 1929, astronomer Edwin Hubble demonstrated that galaxies are receding, corroborating the universe's expansion.
