The fact that its period is shrinking is a good sign for those who expect to detect gravity waves, but we still haven't seen them.Chris Hibberthttps://www.blogger.com/profile/12235621011708498622noreply@blogger.comtag:blogger.com,1999:blog-14297067.post-43516087658066956262010-02-23T17:18:35.237-08:002010-02-23T17:18:35.237-08:00With electromagnetism, actual photons move from pl...<i>With electromagnetism, actual photons move from place to place, carrying the influence.</i> It sounds so clear ... and yet ... When a photon leaves a source, is it travelling in a definite direction? Wave-particle duality and QM say "no it is not". <br /><i>... binary star collapses. Those seem like dynamic enough changes that they should result in a change in the gravitational field that would have to propagate at some finite velocity.</i> There is a bound pulsar pair that appears to emit gravity waves because it definitely is losing energy -- the period is dropping. The energy loss matches what relativity predicts.Robert Ayershttps://www.blogger.com/profile/15220457769907242257noreply@blogger.com
