The evolution of the universe has always been a mysterious problem, hundreds of theories have tried to describe such an existential topic both from a philosophic and a scientific point of view.
How and when was the universe formed? Is it infinitely big? Will our universe “die”? These are just some of the questions that we would like to deal with when talking about Universe. Most of us will say that it’s almost impossible to answer even to just one of them, but they might be wrong…
Did you know that there are three equations, called the Friedmann equations, that can help us find a solution for all these incomprehensible interrogatories? Do you want to know more about them? Stick with me and I’ll tell you everything in a moment.Several different views about the universe started to arise during the nineteenth century with the development of astronomy and the use of telescopes. The major belief was that our universe must be stationary and infinite, like a little balloon that never changes his size. Unfortunately, nobody managed to create a theory that explained how the universe was formed. As a result of that, the scientific community was considering our world as something that has always existed, something totally immutable, boundless and infinite.
