If you’re asking yourself which is the way of beginning of universe, here is answer.
There are a lot of theories that explains how universe began. One of they is Constant condition. But the most accepted is theory of Big Bang. Theory of Big Bang says that in the beginning of universe all matter gather into the one item in which were unmeasured density and huge temperature.
In one moment that item exploded and universe started to spread out. That explosion wasn’t real explosion. Namely, in explosion all matter would fulminate on all sides per capacity, but in the beginning there was no space so matter couldn’t fulminate anywhere. That is the reason we say Big Bang was the moment when universe started to increase.
How Big Bang seemed from nearness. In one little bit of second universe attained a size of orange. One second later, it was large like whole Solar system but million times warmest then Sun. In this moment arise protons, neutrons and electrons.
Into a following five minutes, universe increased and assumed the look of mash. That time is calling: space mash. Then formed first atoms: deuterium (isotope of hydrogen) and helium.
300 000 years later arise atoms of hydrogen. Nebulas of hydrogen, helium and lithium (in minor quantity) started make proto-galaxies. Sun, in this galaxies began procreate first stars.
For following some millions years, stars slowly form a little galaxies. These little galaxies in the time forgathered and there rose the galaxies we know today.
Big Bang left behind the cosmic background radiation, a large quantity of helium and the galaxies that getting ahead between.
