Bookmark or Share- Mathematically, what is a graviton? - Physics Stack ExchangeThen you write the metric field as. gμν =ημν +hμν. g μ ν = η μ ν + h μ ν. Here gμν g μ ν is the spacetime metric tensor; ημν η μ ν is the background metric tensor (Minkowski metric), and hμν h μ ν is a symmetric tensor that represents the difference between the two. As long as your spacetime is topologically R4 R 4 ...
- What is the difference between gravitons and gravitational waves?10. What is the difference between gravitons and gravitational waves? So as I understand, gravitational waves are predicted by and part of the theory of general relativity, whereas gravitons are predicted by the standard model. We have indirect evidence for gravitational waves? So it seems that they probably exist--but what about gravitons?
- Is there a possibility for discovery of anti-graviton, i.e. the ...A graviton is postulated to be chargeless particle state. Moreover, it doesn't have any other quantum numbers (aside from spin) that would need to be conserved. Therefore, a quantum state with the requisite energy, momentum and angular momentum can evolve into a lone graviton without breaking known conservation laws.
- quantum gravity - What do gravitons do? - Physics Stack ExchangeTdonut. 2,325 8 22 33. 4. You are basically asking how forces work in quantum field theory, because the graviton is the force carrier in a QFT description of gravity. Have a read through this article by Matt Strassler. It gives a good description of what virtual particles like gravitons are, and how they work. – John Rennie. May 2, 2015 at 6:23.
- Nature of gravity: gravitons, curvature of space-time or both?The rigorous soft graviton theorem was established by Gross and Jackiw in Phys. Rev. 166 (1968) 1287. As far as I remember, they consider a graviton scattering by a spin-0 particle, but the theorem is valid for any spin because of the reason I mention above. $\endgroup$ –
