Thanks. So the granular nature of matter prevents anything from being in 'contact' with anything else. The particles communicate with forces, and their own accelerations are limited to finite values (and large accelerations sap energy via gravitational waves).
Though can someone clarify the...
In the scenario you have given, the magical instantaneous disappearance of the sun would result in a magical disappearance of gravity immediately for the entire solar system thereby magically sending a signal moving at a speed greater than c.
Ok, I'm confused again. Right, the mass can't just...
Thanks guys, that makes sense, but one more thing.
