 Everything has a beginning even if this thing is universe itself, Einstein said in the general relativity that universe has a beginning as well as it has an end. And there's a lot of theories which speaks about the birth of universe, the most correct one is the Big Bang or the titanic explosion theory.
This section includes the following topics:

• Big Bang theory.

• The first minutes of the titanic explosion (Inflation theory).

Big Bang Theory:
 In 1915 Albert Einstein assured in his general relativity that the motion of any cosmic body leads to the bending of the space around it, so the other bodies will be affected too, and expected that the universe is not static but it dynamic but the old thought was much stronger Einstein too failed when he tried to find a relation between the constancy of the universe and his theory, in 1922 Alexander Friedmand announce that there is a contradiction between the static universe and the lows of physics , Edwin Hubble also discovered that the Milky way is not the only galaxy in the universe , and “George Lemaitre” presented the “Titanic - explosion" theory in order to explain the origin of the universe , and it is the most correct theory from 1927 until now , the universe in this theory must have been formed from a very tiny atom , with endless heat and density which explodes with an indescribable force which caused the expansion of the universe until now, Hubble too assure that by finding the velocity of the expansion of the universe and it was called steady state theory, and it said that universe has neither end nor beginning and this theory interested a lot of scientists, but they couldn’t find any relation between it and the atomic theory, because it’s impossible to an atom to be created from nothing, so “George Gamov” challenge this theory, and assured the titanic explosion theory, he called it “big bang” theory. He said that there is a beginning and a limit to universe and titanic explosion has emitted a lot of waves and heat, and these waves must have described now, and the discovery of the cosmic microwave by the 2 engineers “Arno Penzias” & “Ropert Wilson”, destroy any other theory in 1965, and it was the first time that all scientists believe in only one theory about the origin of the universe, they also said that the atom which has exploded is very rare (singularity), and the waves which resulted embodied forming the fundamental bodies in universe (according to quantum theory Max Blank said that waves can change into bodies and vise versa) like proton, electron and neutron, and another sub atomic particle like  gluon, graviton, then the atoms combined forming molecules, then stars, galaxies and collections.

The first minutes of the titanic explosion (Inflation theory):
 But how are the elements in the universe formed? The scientist “Alan Guth” answered this questions as he discovered another theory which is the ‘inflation theory’, and it was accepted by every scientist, and in this theory he explained the first 3 minutes after the titanic explosion, according to this theory the titanic explosion followed by a huge fireball in an extreme temperature after one part from many millions parts of a second, the temperature decreased to 10²² K, where the fundamental bodies is formed and after 10^{- 6} seconds the ‘singularity’ became as big as a solar system (it’s radius is 588 x 10¹⁰ ),when the temperature became 10⁹ K the radiation became to be emitted after the first second the reaction stopped but universe is still expending until now.
The “inflation” theory is considered very important because we knew the 1^st minutes after the “Titanic explosion”, and it’s very mysterious explosion because it’s not such a normal explosion to the matter in space but it was the explosion of space itself.
