L’espace-temps gravitationnel et ses produits - les ondes gravitationnelles - n’existent pas. S’ils existaient, ce serait un coup mortel pour la mécanique quantique, comme le montrent les textes suivants :


http://www.newscientist.com/article/mg20727721.200-rethinking-einstein-the-end-of-spacetime.html « Rethinking Einstein : The end of space-time (...) The stumbling block lies with their conflicting views of space and time. As seen by quantum theory, space and time are a static backdrop against which particles move. In Einstein’s theories, by contrast, not only are space and time inextricably linked, but the resulting space-time is moulded by the bodies within it. (...) Something has to give in this tussle between general relativity and quantum mechanics, and the smart money says that it’s relativity that will be the loser. »

http://fqxi.org/community/articles/display/205 « If you’d asked Einstein, he would have told you that time is another dimension, much like the three dimensions of space. Together they knit together to create a spacetime fabric that pervades the universe. This notion of time as a dynamic, flexible dimension forms the basis of his immensely successful general theory of relativity, which explains how gravity manifests on cosmic scales as matter warps spacetime. On the other hand, however, the equally celebrated theory of quantum mechanics, which governs the nanoscale behavior of atoms and subatomic particles, says that time is unaffected by the presence of matter, serving as an absolute background reference clock against which motion can be measured. »

http://www.sciencemag.org/content/early/2015/08/05/science.aac6498 « In Einstein’s general theory of relativity, time depends locally on gravity ; in standard quantum theory, time is global - all clocks »tick« uniformly. »
