Question:
I was curious if Gravity has a speed? What I mean is, if the Sun was to immediately disappear, how long would it take for the Earth and other planets to veer off course.

Is gravity an instant source?

Replies:
Gravitational effects propagate at the same speed as light, at least in vacuum.
