There is nothing like Gravity.

introduction-
Newton discovered gravity. he sat under an apple tree in Botanic gardens of Cambridge.
In 1905 Einstein released his papers therby saying that there is nothing like gravity. Newton didn't know about the dimensions of the universe and established the principle that if the sun is destroyed without any notice,then the planets will leave the orbit and will move in random direction
Einstein said that the sun,planets,comets etc. are bound to each other through a fabric of Space-Time.
the interpretation is that the Heavenly bodies have mass and as a result of this they curve the space around them. We call this as Space-time curvature.
Consider the case of our solar system. we have sun at the center. The mass of Sun is round 332900 times the mass of earth.
it is due to this enormous mass that the sun curves the space around it.This curvature is so huge that the planets and the other heavenly bodies of the system which revolve around the sun MOVE IN THIS CURVATURE. There are disturbances in this Space-time strings which we call as Gravity.
So consider the example of a Bedsheet. Put a heavy load in it. there will be curvature and on dropping a pebbel that pebbel will move towards the heavy load.
If this happens,the Unvierse will become instable and all bodies will move towards the center of universe and collide.
But in case of universe the bodies are moving. So they have motion. As other bodies around them also curve the space, there is balancing of forces.
The planets are placed in each others curvature. so they dont collide.
We can say that The milky way makes a big curvature of space,in that curvature the solar systems are embeded and in them we have planets embed in the solar system's curvature. the natural satellites are embede in the curvature of the planets
