In Newtonian physics gravity is a force and in relativity it's curved spacetime if I understand it correctly. So my question is, does the gravitational field of an object look different to different observers? What I mean is, does one reference frame see the strength of the field to be greater or lesser depending on it's relative motion? My physics professor said yes, but a quote from "Exploring Black Holes" by Wheeler and Taylor has me wondering. It says "Special relativity uses laboratory and rocket frames as different vantage points to get an insight into flat spacetime that exists independent of any reference frame. In the same way we use alternative reference systems around a star to get insight into curved spacetime-a curved geometry that exists independent of any frame of reference." My apologies if this has been asked before, or if the answer should be blatantly obvious.
