BIG BANG THEORY

creation of the universe and solar system

When the man came into consciousness, then things started bothering him in the earth, such as how earth form? What is the universe and how it form? What is the universe? And to explain all this, the Big Bang Theory was born, the Big Bang theory also called it the theory of the Great Explosion.

When the man lifted the head from the earth, he saw the sun on his left side and on the right side he saw many planets, meteorite galaxies, and the human race found that all of them were running away from each other, that is, away from each other. Man has thought that if all these planetary stars are spreading meteorites, they must have been together at some time and we went back in time and found that there was a time when all the planets were starring Galaxy were together that he reasons were stated singularity and assigning 6 main reasons the origin of the universe from there.

‌Origin of our universe-

‌1. THE BIG BANG THEORY

The most widely believed theory of these is the theory of great explosions. The theory of great explosions is The BIG BANG THEORY. This is the most valid scientific theory. In the beginning, all matter would have been contained in a point if we were on time. Go billion years ago, you will get an infinite density and a point of infinite temperature called singularity and its time period is 1 plank time (10 ^ -43 sec). Will all force (gravitational During this period, weak nuclear, strong nuclear, electrostatic) is to be integrated so that unstable universe has begun to expand and spread to date before the big bang

- Inflation occurred in ‌10 ^ -32 sec

- Protons formed up to micro1 micro sec (10 ^ -6)

- Nuclear fusion array up to ‌.01 sec

- Nuclear fusion ends by in 3 min

- 83.8 lakh years This is the time that gives proof of the big bang is correct, here the first hydrogen atom was formed due to which visible light came out and the visible universe came into existence and this point was received by scientists and speculated that the universe Must have originated from the big bang

- 3Lakh - Starting stars in the middle of 300 million years

- The formation of the Milky Way between ‌ 300 million to 13.8 billion years

- Today's universe after 13.8 years

2. Steady steady-state theory

This theory opposes the theory of big bang and says that matter is always formed, that is why the universe is expanding. This universe had neither a beginning nor an end. This theory gradually vanishes. Gone.

3. ‌Eternal inflation Theory Infinite inflation theory-

सिद्धांत This theory states that the Big Bang must have taken place in infinite directions, which would have created an infinite universe which was called the multiverse.

4. Oscillating universe theory-

सिद्धांत This theory says that the universe is formed and deteriorates. The formation of the universe is called the big bunch and the universe deteriorates. When the energy of the outbreak of the universe is exhausted, then a big crunch will come and then the whole substance will come in one place. Will be assembled again big bang and this process will go on indefinitely.

5‌ Brain model brane modal-

 The universe is made up of huge membranes called brains that keep colliding with each other. The process of spreading the universe again after colliding is called Big Bang.

6. Exotic theory Unique Theory

(i).   Hologram theory of the universe

(ii).  Creationism - Principles made by different religions about the origin of the brand

(iii). Simulation Theory- According to this, we are living in a computer program, the real world is quite different from this world as shown in the matrix movie.

So this was all about the origin of the universe, Big bang theory.
