That reminds me of something I thought about years ago. My question was as follows: Let's assume there was a hypothetical technology invented that could teleport stars. Someone teleported the Sun to a remote location, one in which its gravity effect on the solar system would be negligible. Would the solar system continue to orbit around a non existent sun until the gravity stopped reaching them? If you were on Earth, it'd take roughly 8 minutes to realize the sun was gone, as we're 8 light minutes from the sun. If gravity propagates at an infinite speed, that presents some interesting situations. So would we be moving (on a planetary scale) in a way that's totally baffling for 8 minutes until we realize the sun is gone?

I may have to look into this some more. And yes, I realize how ludicrous the idea of being able to transport stars is.
