The best-supported theory has been that of the Big Bang, which speaks of a large initial explosion. However, many times we ask ourselves what was before this? or what caused the big bang? The answer is nothing, because before the expansion of the Universe there was no matter, space or time.
What it is possible to believe until today is that at that moment the Universe must have been very hot, since a gas when expanding cools, which in the end has made the Universe since the explosion until our days.
At first the only thing that could be perceived was an immense ball of fire, a time that was known as the age of leptons. We can not yet speak of the existence of atoms, since their three main constituents-neutrons, electrons and protons-had the ability to coexist in equilibrium with other particles. Later the temperature of this huge ball dropped considerably, and only the attention would be focused on the protons, electrons and neutrons, the rest of the particles disappearing.
From here on the so-called plasma age begins, where the temperature dropped enough for neutrons and protons to combine, giving rise to helium atoms, which contained two protons and two neutrons.
700,000 years later, electrically neutral atoms could only be formed thanks to the combination of protons and electrons, ending the era of plasma. From this moment, the radiation existing in the Universe stops interacting with matter, beginning its slow cooling until today.
Certain fluctuations in the primitive Universe must have grown enough to reach a point where the force of gravity within the fluctuation began to overcome the expansion, acquiring its own identity. Once this fluctuation began to contract it did not remain homogeneous, which eventually gave rise to clusters of individual galaxies and galaxies.
The Big Bang
During the first seconds, the temperature was more than a trillion degrees and all the energy was in the form of radiation. During the first 10 seconds the elementary particles were formed and after 15 minutes hydrogen and helium nuclei were formed, in a ratio of four to one. About 10,000 years later, the temperature had dropped to about 100,000 degrees and the first hydrogen atoms formed. After about 400,000 years, hydrogen began to condense into clouds (the future stars), which in turn were grouped into larger clusters (future galaxies).
11,000 million years ago, the temperature of the universe was about 3,000 degrees, and the first stars formed: gravity caused the nuclei of many hydrogen clouds to reach high temperatures, of the order of 15 million degrees, which allowed the fusion of hydrogen in helium, a process that causes the luminous emission of stars.
When the stars deplete the hydrogen in the nucleus, they are able to continue generating energy by fusing the helium in heavier materials. In this way, in the nuclei of the first stars, all the chemical elements that now exist on Earth were formed. In the larger stars, this process generates more and more energy, until there comes a time when gravity is not able to contain it and the star explodes by throwing a large part of its matter into space. This happens at a different age according to the mass of each star.
The explosions of stars filled the space with new gas clouds (this time relatively rich in the whole range of chemical elements), from which new stars were formed, the so-called second generation stars, among which is the Sun.

great one
thanks bro
try to Understand my quest
if there was nothing then how the space came in to existence
my question is if there was no matter nothing then how the universe can in to existence.
if matter can never be created or destroyed
nor*
Sorry!
no it is fine

hi friend
here's your answer looking for
basically, in order to give your answer. we have to first understand about the big bang.
there is many contradictory points of this theory but however many of these points Proves its existence too.
so, according to the theory, 18 billions years ago our universe was in a point mass in which all the four fundamental forces of Universe was in the form of radiations such as gravitational force, strong nuclear force, weak nuclear force and electromagnetic force.
and because of this , the temperature was trillions of degree. and in this tremendous temperature the atom cannot be form. it needs some specific temperature to be in existence. so this tremendous temperature form the highly ionized plasma that was the quark gluon plasma. this is the sixth state of matter that is formed at very high extreme temperature. in which quarks and gluon get melted to form quark gluons plasma.
Even, at this temperature, there was no light and that's why this period was called as the dark period. because of this tremendous temperature the light also was not in the existence and they cannot form the photon packets.
in a microsecond, temperature get decrease by million of degrees. now time came when the atom can be in existence. so the photon packets start to form but the rays of a light was redirected by the free electrons.
now the Atom was in the existence. this was the time when the quarks Were are combined to each other by gluons. now because of this hadrons were formed . and this results as the formation of neutron and proton. as there was the free electrons in the surrounding that was redirecting the light rays. because of the gravitational pull and electric charge they get attracted by the protons. and now they form the atom of Hydrogen. and later by the fusion the two hydrogen atom get fused together to form the atom of helium.
and as we now get the two most primary elements by which the whole universe is formed.
now this was the time of the formation of first star. because of the gravity the all the atom of Hydrogen and Helium get concentrated at the core.
and because of the cosmic dust and the Other particles the planets get formed.
and they start revolving a particular star because of the curve in a spacetime.
at this time our solar system was also formed. in which our earth was also included. this was the time of tremendous heat on the earth. and because of this tremendously heat the life was not possible on the earth. but there was the clouds of H2O and many other elements. that later condensed and precipitation occurs by which the temperature get decreased.
now, after this precipitation the oceans, rivers and streams were in the existence.
this was the time of the life on the earth, coincidently the possible pattern of the protein ( amino acid) was formed in the water. and this pattern form the most primitive organism that is Paramecium. and now by the evolution many of the organisms get evolved from one another. and now live was in the existence.
this all information about how the matter was created during the formation of Universe and how the life formed.
till now our universe is expanding because of the dark energy. and all the thanks in the space are moving farther from each other.
and because of this the wavelength of a light is also stretching that is resulting as the decrement in the wavelength of a light.
and this cause the formation red light.
hope you are satisfied with my answer
