...in the form of what may be an accidentally discovered artificial gravity generator, with possible practical applications!:
http://www.esa.int/SPECIALS/GSP/SEM0L6OVGJE_0.html If this effect is real, it's fully 1/10,000 G -- which is not to be sneezed at, and might conceivably lead us to Bigger Things. |

Heeeeemmmm...
many wild speculations in latest posts. Many words that relativity scientists themselves will not understand. Cool, guies, cool. If the effect indicated is real, it implies many theory by knowledgeable people before we ignorants understand it. And if the observed effect was simply the deformation of the frame of the experiment aparatus under the heavy strain of a strongly accelerated large disk, no matter of what it is made of? It would produce the same output from the accelerometres than a magnetogravitationnal field, and be proportional to acceleration too. And easily larger than a magnetogravitationnal field... I think we all wish that one day would be discovered something allowing us to travel in space as easily as in Starwars. But nothing proves that it really exist. Experiments like this one must be monitored carefully, as they have the potential to lead to important discoveries. But usually they don't. This thread reminds me the one about Heim which was also using a rotating disk and interaction between gravitation and electromagnetic field to drive a spacecraft. |

Good cautionary note, but as I read the experiment, they controlled for the rotating mass by monitoring the effect both above and below the superconductive transition. Something else could be wrong. Particle physicists have never been able to weld a path between GR and quantum observables, and the fingers have always pointed in both directions. Since partical physics are at least phonomonologically derived, if confirmed, this paper would tend to throw GR out-of-the-boat first. But stay tuned, because once the attributes of this 'induced Newtonian metric' are understood, Planckian limits are next in-line... |
