Big Bang Theory
This is the most valid theory regarding the origin of the universe.
This theory was propounded by the Belgian astronomer and priest Georges Lament or in 1960-70 AD. According to them, the universe was a giant fire body about 15 billion years ago, which was formed from heavy materials.
There was a scattering of substances due to a sudden explosion in it. Due to which black and normal matter were formed, and their aggregation led to the formation of many cosmic bodies.
There was an accumulation of normal substances around them, due to which their size increased. Thus, galaxies were formed. In these, innumerable bodies formed from the accumulation of substances emanating from the explosion are called stars.
This process also led to the formation of planets and satellites over a period of time. Thus, the universe originated from the 'Big Bang' phenomenon, since then the universe has been expanding continuously. Continues. As evidence of this, reference is made to the increasing distance between the galaxies.
Scientific experiments of the mystery of the universe
In order to unravel the mystery of the universe, the European Center for Nuclear Research, CERN, on March 30, 2010, successfully conducted a historic experiment called the Large Hadron Collider in Geneva, 100 feet below the Earth's surface and in a 27-km-long tunnel.
It involved more than 1000 scientists. In this, the beams of protons collided at almost the speed of light, the creation of 'Higgs Boson' was used.
Scientists want to replicate the phenomenon of cosmological origin in the laboratory, which in the world of science is called Big Bang.
Star life cycle
Due to the rotation of the sky, the clouds of gases existing in the universe are affected and due to mutual gravity, nuclear fusion starts in their center.
The process of conversion of hydrogen into helium begins. At this stage it becomes a star.
Due to the depleted hydrogen of the center, the central part of the star becomes compressed and heated, but the hydrogen continues to be converted into helium in its outer layer.
Gradually, the star cools down and becomes red, which is called a blood demon.
After this, helium starts converting into carbon and carbon into heavy substances like iron. This results in a rapid explosion of stars, which is called supernova explosion.
If the mass of a star is less than 1.4 Ms (where Ms is the mass of the Sun), it loses its nuclear energy and turns into a white dwarf, which is called a fossil star.
White dwarf cools down and turns into Black dwarf.
1.4 Ms is called Chandrasekhar limit. If the mass is more than this, the free moving electrons leave the nucleus at high velocity and leave the nucleus and neutrons remain, this state is called neutron star or pulsar.
The neutron star keeps on shrinking for an infinite amount of time, that is, a large amount of mass in the neutron star eventually gets concentrated in a single point. A body containing such infinite density of matter is called a black hole or black hole.
No matter, even light, can escape from this black hole. This black hole can never be seen.
John Wheeler is credited with propounding the concept of a black hole.
A raga black hole is a group of two or more black holes.
A quasar is a bright celestial body that emits enormous amounts of energy.
NASA has discovered the oldest star ever identified, which has been named 'Kepler 444'.
