Gravitons found
WebGravitons are hypothetical, but they're far less hypothetical than most of the other particles which theorists speculate about (such as axions, magnetic monopoles, strings, sterile neutrinos, and the like).. That probably sounds a little strange. Let me explain. We don't have a complete theory of quantum gravity. But we do actually have an extremely good … WebApr 9, 2024 · The team found these hypothetical gravitons while hunting for evidence of extra dimensions, which some physicists suspect exist alongside the observed three dimensions of space and the fourth dimension, time. In the team's theory, when gravity propagates through extra dimensions, it materializes in our Universe as massive gravitons.

WebJun 21, 2024 · Optical gravity could profoundly alter geophysics and astrophysics. In Figure 1, gravitons are also being exchanged between A and B directly (gray bar). If A and B are relatively close to each other, however, these gravitons are coherently superimposed on the local spacetime structure incorporating A and B and so do not cause a repulsive force. WebFor this model we have previously shown that in a radiation dominated Universe, where the second, fixed brane is arbitrarily far away, no gravitons are produced Cartier et al. ().
