This is a question about electromagnetic waves and gravitational waves.
Let's say we're on the Earth and we're looking up at the sun (safely).
If the sun were --for some reason-- to violently and dramatically jerk from its position, how would we first find out?
Would we first *see* the sun move?
Or would we first detect a change in our orbit?
Would the light, the electromagnetic wave, reach us first, or would the gravitational wave reach us first? Would they happen at the same time?
