THE BIG BANG
The Big Bang
The Big Bang Theory was given by Georges Lemaître. This was only his asumption that The Mighty Universe was only a single point of Energy.
In the starting, universe was only an atomic size energy. When there was no time, no planets, no suns or stars. Then suddenly Big Bang occurred, this atomic sized energy burst into small particles of pure energy. These small particles started expanding at the speed of 3x107meters per second (a million times faster than the H-bomb) .Then these energy particles started breaking down into protons, neutrons and electrons.
This is how matter and anti matter formed. Anti-matter is the opposite of matter, so when these come together they destroy each other. But here fortunately the quantity of matter was more than quantity of anti-matter, so some matter was left. And this matter started storing and formed a balls of matter. Then these balls started to explode. And then molecules of hydrogen started forming. From hydrogen molecules, helium and other gases formed. Other matter continued to expand.
After 400 million years, gases like Hydrogen and helium come together to form stars. Stars are massive balls of fire containing two main gases hydrogen and helium. Helium is a very hot gas.
Around these stars the other matter and gases started revolving because of magnetic force of star. These matter and gases took a spherical shape because of revolutionary and rotational motion around star and on its axis. This is how planets are formed. Also some matter started revolving around planets because of magnetic force of planets. These are called moons of planets. And some matter that don’t come in the magnetic field of both these (stars and planets), move freely are called asteroids. Now after 13.8 Billion years, there are almost 1011 Galaxies in universe and on average each galaxy contains almost 1011 stars. We can see clear difference between the number of stars and galaxies in universe, it means that universe is being constantly being expanding.
