What is BIG BANG 💥

As the universe cooled, elementary particles like quarks and electrons began to form. These particles eventually combined to form atoms like hydrogen and helium.

Over millions of years, gravity caused these atoms to clump together, forming galaxies. Within galaxies, stars and planets formed from these clumps of matter.

As the universe continued to expand and cool, the radiation from the early hot phase stretched and cooled to form the Cosmic Microwave Background, which we can still detect today.

The expansion of the universe continues to this day. The observable universe is the part of the universe we can see, and it is constantly expanding as galaxies move away from each other.

The Big Bang theory is supported by various pieces of evidence, such as the observed expansion of the universe, the cosmic microwave background radiation, and the abundance of light elements like hydrogen and helium. It provides a framework for understanding the origin and development of the cosmos.
