- awj 15y agoIf I send a slow, waddling mobster to go break your kneecaps, are you affected when I give the order or two weeks later when Guido knocks on your door?
- polyfractal 15y agoGood point, I retract my comment :)
- bakedbeing 15y agoOnly if gravity moves at the same speed as light, right? It sounds like we've been observing energy emissions (light) rather than directly observing it's gravitational impact on us.
- ars 15y agoGravity has to move at the same speed as light. If it didn't it would cause time paradoxes.
- bakedbeing 15y agoAh of course, a theoretical graviton being a massless particle. That's what I get for not having a wee Google first.
- awj 15y agoMy understanding (note: I am not a physicist, this is not a physics lesson) agrees with ars, gravity has to move at the same speed as light. In either case, the energy emissions potentially are enough, if they're directed at us and strong enough.
