Big Bang: The Event that Caused Creation of Universe

Our universe is approximately 13.8 billion years old. We all know that the universe was created with an explosion of space itself - the Big Bang. Over these billions of years, gravity caused gas and dust to form stars, planets, galaxies and other celestial objects.

A Constant Expansion

Our universe has been expanding since its creation. Estimates by scientists say that the universe expands around 68 kilometres per megaparsec. However, there is a theory that states that one day, the universe will stop expanding.

The Big Crunch Theory

The Big Crunch Theory says that as the universe stops expanding one day, gravity will pull on matter, and the universe will begin to contract. Everything within the universe will crush following the contraction.

The Universe May Form All Over Again

Some scientists believe that the Big Crunch would lead to the universe forming all over again. There is a hot debate among the scientific community about how realistic this theory is.
