The VIRGO project in France and Italy and the GEO 600 project in England and Germany are both involved in trying to detect one of these.
The VIRGO project in France and Italy and the GEO 600 project in England and Germany are both involved in trying to detect one of these. One argument against its existence is that general relativity says that what it mediates is not actually a force at all. Like a photon, it would be massless, uncharged, travelling at the speed of light, and only be emitted by accelerating, massive objects like stars. By definition, this particle would apparently be identical to its antiparticle. FTP, identify this postulated boson that would be the carrier of the gravitational field.
