Hi, everybody. Can anyone settle this question that I've been puzzling about? If an object with a small rest-mass, say, an apple, were to whiz very close past you in space with a relative velocity so great that its mass, as measured in your own inertial frame, was comparable to the rest-mass of the sun, would you experience any gravitational effects as it passed by? Considered in its rest frame it is obvious that such a small mass has a negligible effect on the geometry of space-time. Which at first inclined me to think, even though it seems slightly paradoxical, that you would feel nothing as the object went past you. But then I had doubts. I'm pretty good at special relativity, and have made a start at general relativity, but solving even simple problems in GR is a little beyond me at the moment. Thanks.
