The beginning of the universe is from the big bang which is a massive explosion.
The Big Bang is the moment when the universe began 13.8 billion years ago with the explosion of a small, dense fireball. However, what caused the explosion in the first place remains a mystery.
A Big Bang event is a physical theory that explains how the universe expands from a dense and hot initial state. Various cosmological models of the Big Bang explain the evolution of the observable universe from the earliest known epochs to later large-scale forms.
In 1929, Edwin Hubble provided the first observational evidence that the age of the universe is finite. Using the largest telescope of its time, he discovered that the farther away a galaxy is from us, the more it appears that the space is expanding from us in all directions.
