How do you calculate the speed of gravity using general relativity?

This implies that equation (17) gives a solution to the wave equation (16)
if [itex]k_a[/itex] is null; that is, tangent to the world line of a photon. This shows
that gravitational waves propagate at the speed of light.
The formula for calculating the speed of gravity in GR (General Relativity) is c=1/sqrt(1-2GM/rc^2), where c is the speed of light, G is the gravitational constant, M is the mass of the object, and r is the distance from the object.
The speed of gravity is not a constant like the speed of light. In GR, the speed of gravity is dependent on the gravitational field and changes with distance. In contrast, the speed of light is a constant in all frames of reference.
No, according to GR, the speed of gravity cannot exceed the speed of light. This is because the theory states that nothing can travel faster than the speed of light in a vacuum.
Yes, the speed of gravity has a significant impact on everyday life. For example, the speed of gravity determines the orbits of planets and the movement of celestial bodies in the universe.
In GR, the speed of gravity plays a crucial role in the theory of relativity. It is a fundamental concept that explains the curvature of space-time and how objects with mass interact with each other.
