| Dec 13, 2010 at 15:19 | comment | added | Marek | @Gerard: yes, in a sense you could think of the space-time as a kind of 'ether'. Although it's much more sophisticated that the naive concept of ether people proposed before SR. | |
| Dec 13, 2010 at 14:05 | comment | added | Gerard | Of course, nothing new. When GR introduces a mediator, maybe it can be compared to the 'ether' concept. That was a mediator too, and after discarding it in SR a new mediator was introduced in GR? | |
| Dec 11, 2010 at 23:36 | comment | added | Marek | @Gerard: what about it? It should be completely natural. Just take Newtonian gravity: one piece of matter (Earth) tells another piece of matter (Moon) how to move. GR just adds a mediator of that action. | |
| Dec 11, 2010 at 23:31 | comment | added | Gerard | J. Wheeler's phrase: 'matter tells spacetime how to curve, and spacetime tells matter how to move' implies that matter tells itself how to move - now what should we make thereof? | |
