Question

Why does gravitation exist? Why is Newton's Universal Law of Gravitation true????​

Answer 1

Answer:

$</p><p>\huge\mathfrak{Universal\:law\:of\: gravitational}$

this law states that the force of attraction between two particles is directly proportional to the product of masses of two particles,and this force is inversely proportional to the square of the distance between these particles.

let's particles have masses m 1 and m 2 ,and the distance between these particles is r

F →m 1 ×m 2

F → 1/r^2

so ,

F = G m ×1 m 2 /r^2

here G be the gravitational Constant .

is it true ……?

the graviton is a massless state of a fundamental string.

If it true, the graviton is expected to be massless because the gravitational force is very long range and appears to propagate at the speed of light.
