Speaking in simple language as you may know universe comprises of all the things that exist like our earth, our solar system, our galaxy,  billions of other galaxies and many other things which are both intresting and mindblowingly amazing like Black-holes.

The approximate age of  our universe is around 13 BILLION years (i.e. 13000000000 years), and there are more than 100 BILLION GALAXIES in the observable universe( that part of the universe that we can observe from earth in the present day.) The universe as we know it is the result of BIG BANG.Scientiest believe that around 13 billions years ago all the mass of universe was contained in a small area and after ix exploded the universe started to expand (It still does).

The universe is very large and possibly infinite. Just think about it:-
Sun (which is an average star) has adiameter 109 times that of earth) is one of  200 to 400 Billion stars of our Milky Way, which is infact one of 100 billion  galaxies in this universe,
Infact there are more stars in the universe than grains of sand on all the beaches of Earth.
If you are amazed (even if not) there is a further possibility that our UNIVERSE itself is one of many universes in a MULTiVERSE system.
There is on quote of Albert Einstein that describes it all
"The only thing incomprehensible(something that can't be understood ) is that it is comprehensible (understandable)."

As this blog moves on you will come to know more about universe & in case there is something You know and want to sharel  I beg you please tell me and others.
