In order to preserve information causality, spacetime cannot deform instantaneously. i.e., an object X in a frame with relativistic speed near c compared to an observer O. O will be unable to detect X by any means until X is very close. Also, my money is on frame-dragging and Einstein&amp;#x27;s figures being within half a standard deviation. http://arxiv.org/abs/0911.4718&lt;/p&gt;&lt;p&gt;&lt;a href="https://hackerpaper.kaipfister.de/p/0911.4718/"&gt;Paper and discussion history&lt;/a&gt;.
