The Big Bang theory is a scientific theory that explains the origin and evolution of the universe. It’s important because it:
See lessExplains the universe’s expansion
The theory explains how the universe expanded from an extremely hot and dense state to the cooler and less dense state it is in today.
Explains the presence of matter
The theory explains how the universe came to contain the matter and radiation that make up stars, planets, and galaxies.
Explains the physical laws
The theory explains the physical laws that govern the universe.
Explains the origin of hydrogen and helium
The theory explains where the hydrogen and helium in the universe came from.
The Big Bang theory is based on a combination of observations, mathematical modeling, and experimental evidence. The theory suggests that the universe began about 13.8 billion years ago in a singularity, a point of infinite heat and density. This singularity contained all the matter and energy that would eventually form the universe. The universe then expanded rapidly, faster than the speed of light, in a period known as cosmic inflation.
