A Conversation for Gravity
Gravity Query
Zucchini Started conversation Aug 26, 2002
I've been pondering: Gravity is weak but acts at infinite distance. How `fast` is gravity? i.e. at what speed would a `graviton` travel?
In a mind experiment you could create a mass where there was once none, and time how long it takes for nearby masses to be influenced by the new gravity. Not possible in reality though... (think of the gravity quakes!)
If gravity is 'non-local' and acts instantly on every mass (shades of Bells theorem...) where does this put our graviton?

Gravitational waves propagate with the speed of light. Gravitation itself 'propagates' with the speed of light.
By the way, I don't believe in gravitons.
