Question

Action at a distance, such as is the case for gravity, was once thought to be illogical and therefore untrue. What is the ultimate determinant of the truth in physics, and why was this action ultimately accepted?

Short answer

The observation of gravity was great achievement during that time to develop the theories and hence it is ultimately accepted.

Step-by-step solution

Definition of Gravity

Gravity is a universal phenomenon and is introduced by Newton and Derived the expression for gravitational force.

(Explanation)

Through the gravitational force, it was developed the facts about the planet’s revolutions around its orbits.

Using gravitation, almost astronomical problems can be explained and derived to many conclusions.

Therefore, the observation of gravity was a great achievement during that time to develop the theories and hence it is ultimately accepted.
