Is the event horizon of a black hole considered an observer relative location? We, who are at a very large distance relative to a black hole see the event horizon as located a finite distance from the center of the star. If another observer happens to be closer to the same hole, does he detect it as somewhat nearer to the center of the hole?
I have an interesting thought experiment that depends upon the answer to this question. My suspicion is that the perceived horizon location does depend upon the exact location and most likely motion of the observer. Has anyone had an opportunity to actually calculate this effect? Dave
