Everything which possess mass possess gravitational field.
English mathematician and physicist Issac Newton discovered gravity when he saw a falling apple while thinking about the forces of nature.
So, the apple actually didn’t fall on his head !
Humans only recently (like in last 300 years) realized what gravity is all about.
Then came Einstein !
The general theory of relativity says “ gravity arises from the warping of space and time. “
When i first read that, i didn’t have an idea what does it even mean.
I just knew some facts like—
- Light bends when passing near massive objects like sun.
- The clock raised above the earth speeds up relative to a clock on earth’s surface.
I was like “spacenet may be responsible for that.”
This is spacenet.
So, finally after two days of restlessness, I remebered what faded away.
So yes, everything which possess mass possess gravitational force, but why?
It is the “space-time”, which i used to call “ space-net” or “imaginary net.”
The universe is full of this Net and its not 2D net, its 3D, so it is present in every corner of space.
Now,
How gravity is formed→
1. Let a space net be like volleyball net.
Like this→
Note- its not 2-D ,its 3D and it is imaginary.
2. Place the earth which has appreciable mass on this net.
(Never thought i would use ms- paint in my life)
So, the earth applies force opposite to its curved surface area on the space net.
3. Now,
Newton’s third law of motion, “ every action has its equal and opposite reaction”
So, same force is exerted on the earth by the net→
This reaction force is “gravity” which applies on all objects on earth surface towards the centre of earth.
Thanks to Albert Einstien !
ILLUSTRATION→
Suppose on the back seat of a car, there are four person sitting and there is no space left.
Somehow, I popped in the car trying to adjust, and somehow, i managed to secure my space.
But, it is very uneasy over there because i apply force on other four people and in turn they also apply a force on me.
Now, consider, those four person are space net and i am some object trying to fit in between those, so i experience force, which in case of earth is “Gravity”.
