Question

Which statement is a postulate of general relativity?

The speed of light is constant for all observers.

Observers will see the same laws of physics whether at rest or in uniform motion.

A gravitational field is the same as an object moving at the speed of light.

Observers will see the same laws of physics in any frame of motion whether accelerated or not

Answer 1

The speed of light is constant for all observers

Step-by-step explanation:

As per general postulate of relativity

• Lorentz covariance of special relativity becomes a local Lorentz covariance in the presence of matter.

So

light speed c is independent of States of matter
