Time, Light, Energy | The Mystery of the Birth of the Universe

Has the universe ever had a beginning or has it always existed? Indeed, the observations suggest that there was indeed an early moment in this Universe, of which we are a part even now. How can it be? How can "something" arise from "nothing"? And time?

The Big Bang theory is the prevailing cosmological model explaining the existence of the observable universe from the earliest known periods through its subsequent large-scale evolution.


The birth of the universe has therefore involved a huge loss of matter and energy. 

Fortunately, the amount of matter was slightly greater than the amount of antimatter, so the matter survived, even if only thanks to a particle in a billion, and it was this infinitesimal residue to give origin to the universe we know today. 


This is the birth of the universe
