Hii friend,
__________
Here is your answer
___________________
⇒ Every person, planet star and a galaxy is a part of a universe - and even empty space.
⇒ Universe can be defined as everything that exists. It is the biggest thing we have a word for.
⇒ the universe is too big, In speed of light, it would take about 15 billion years to cross it as far as we know.
⇒ The universe has started about 12 - 15 billion years ago, due to big bang.
⇒ Big bang was a huge explosion that created all the mass and energy in our universe in less than a second.
⇒ The big bang was super hot! It is 10^27°C, meaning 10 with 27 zeros after it.
⇒ The effects of the big bang is so strong that the universe is still expanding.
⇒ People who study universe are called as cosmologists.
⇒ Some cosmologists believe that universe will shrink back to a state of high temperature and density.
⇒ This belief in the shrink of universe is called big crunch. It is the opposite of Big Bang.
⇒ Some cosmologists also think that gravity will never stop the expansion of universe and it will keep going on.

THE UNIVERSE :
The universe is unimaginable vast space which includes anything which exist , like stars, galaxy and other heavenly bodies.
The Universe includes Whole of existing space around the earth and all heavenly bodies contained in it. It means the universe includes the earth and all heavenly bodies, like stars, planets, satellites and several other celestial bodies ( heavenly bodies ) that we see in the sky.
The science of observation and study of compsition, behaviour and other Information about stars, planets , moons , asteroids is called astronomy.
BIG BANG THEORY :
The galaxies are not stationary but are moving away from each other at a great speed. Therefore, our universe is not stationary but expanding.
It means that the universe must have been very small in the beginning and at some point in the beginning. Some event must have happened when the universe started expanding. This event is called Big - Bang.
