In 1665,when a falling apple arose the idea of Gravity into Issac Newton's mind.he made a mass effect on people's mind too.The idea of Gravity entirely changed our view of seeing this world.Newton said that their is a constant force which is continuously pulling two objects towards each other,so he termed it as Universal Constant.
I am pretty sure you shall be knowing the rest of the part about newton and gravity...The f=Gmm/r^2 formula,acceleration due to gravity "g" and all other G stuff.
You now are satisfied finding yourself familiar with Gravity.But then comes a German Clerk and introduce two devastating and mind blowing theories which totally proves Newton wrong-The General and Special Relativity.This clerk was none other than Albert Einstein.
According to Einstein,the Universal Constant "G" was not actually Constant.
Consider it like this-All the planets are revolving around the sun in their own axis when suddenly The Sun Disappears.What according to you would happen if their is Gravitational pull?
According to Newton's G concept,all planets should still revolve in their objects but each time coming closure and finally colliding with each other.But this doesn't happen...Also consider that the sun is 8 light minutes away from earth,so we should see the sun disappeared 8 minutes later!!!Is this something sensible?I don't think so...
So,Let's see from Einstein's prospective:-
We see that as soon as the sun disappears(actually we can't see but you can atleast imagine),all the planets move out in a straight line leaving their orbits and we still would come to know 8 minutes later.This theory just shook the father of gravitation...
Their is a wonderful video in youtube that shows how the gravity thingy works.Imagine their is a elastic cloth all over which we call as space like this:-
If we place a heavy mass like the sun is between the solar system,we get a depression in the cloth like this:-
Now imagine that some other big sphere came rolling(comparably less in mass to sun) and due to the depression produced by the sun,started revolving around the sun,we call this revolutionary path orbit.We reason this motion of sphere as a result of some attractive force by the sun and term it as Gravity.
Now many of you would have a problem if they applied the same theory for earth and the moon.It is surely a complex Earth is rotating and at the same time revolving around the sun,then why does the moon revolve around the earth and not join other planets and revolve around the Sun?Well,have a look at this gif:-
Thankyou for Reading!!!

Till now we have seen gravity changing from Newton to Einstein,but what about the gravity that exists in a blackhole???Does it violate relativity?Well that's a topic for some another day...Also if you still believe in this concept then you are messing with wrong guy:-
