Simply put, the equivalence principle holds that all bodies under the influence of the same gravitational field experience the same acceleration, regardless of their mass or composition.

Evidence supporting the first aspect of the equivalence principle initially came four centuries ago.

These two thoughts — free fall feels the same as being at rest in gravity - free space, and accelerating upward through space feels the same as sitting at rest in a gravitational field — form what is known as the equivalence principle.

Because of that equivalence principle, then, the same must be true for gravity: As a gravitational field grows stronger, time slows even more.

This was to measure the bending of light by the sun's gravity, an effect predicted by the equivalence principle.

That formed the basis of what he called the equivalence principle, which serves as the foundation of the general theory of relativity.

A second reason was his concern with incorporating gravity, making use of what he called the equivalence principle, which postulates that observers can never distinguish the effects of gravity from those of acceleration as long as they observe phenomena only in their neighborhood.
