If we have a star, let us give an example of Alpha Centuri and a object orbiting it let us label OBJECT X. assume Object x is 1/2 light years away from alpha centuri. if ( and this will not happen, so this question has little purpose) alpha centuri is wiped out of existance, when will OBJECT X stop being influenced by its gravity?

 

 

suddenly?

 

or after half a year?

 

can no message travel faster than light? and does this link in with the Graviton the assumed particle of gravity

I dunno about the mathematical proof, but we know that gravity travels at the speed of light. We can use that to answer the question (as has been done above).

Can someone link me? Last time I googled this I came across articles saying that gravity was instant, or if not then very fast :/

 

EDIT: Nevermind, just found the new scientist article.
