Why does everything possess gravitational field?

 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”.

Why does the Earth have a magnetic field?

The Earth's magnetic field is generated by the movement of molten iron and other metals in the Earth's outer core.

This movement creates electric currents, which in turn produce the magnetic field. The process is known as a geodynamo.

The Earth's core is divided into two layers: a solid inner core and a liquid outer core. The outer core is about 2,250 kilometers (1,400 miles) thick and is composed of molten iron and nickel. The movement of this molten metal is caused by heat from the Earth's interior and the decay of radioactive elements.

As the molten metal moves, it creates electric currents through a process called electromagnetic induction.

These currents generate a magnetic field, which is strong enough to extend from the Earth's core to the surface and even into space.
