How do Gravitons work? as compared to photons $\begingroup$ (+1) If light deflected near a black hole emits graviton (gravitational bremsstrahlung), how to detect it, and would a graviton look just like a photon with extremely low wavelength? $\endgroup$ –
quantum gravity - What is a graviton? - Physics Stack Exchange A graviton is a particle that carries gravitation So as to explain that: imagine you have two point particles moving away from each other Particle A sends a graviton towards particle B, and starts moving towards particle B Then particle B receives the graviton and starts moving towards particle A
The energy of a Graviton - Physics Stack Exchange Each graviton will then carry about 10^-30 ergs, a very small amount According to the Wikipedia gravitational wave article the sun earth system emits 200 watts of gravitational radiation, but this would typically emit 10^-34 erg gravitons
Mathematically, what is a graviton? - Physics Stack Exchange The rank-2 tensor in 4 dimensions admits 16 free variables Is this the case for a graviton -- all 16 free variables are admitted, no restriction on the freedom? Can one represent a graviton with a matrix If so, can you provide an example of such a matrix --- if for no other reason than to fix the idea
How do gravitons and photons interact? - Physics Stack Exchange Gravitational lensing (light being "bent" by stars for instance) relates to general relativity, the graviton is a theorised particle in quantum field theory There is currently no complete and accepted theory of quantum gravity which connects the two
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 $\endgroup$ –
gravity - Is the graviton hypothetical? - Physics Stack Exchange Gravitons are the particles you get from quantizing General Relativity Since we don't know yet how to correctly quantize GR (or whether trying to quantize it is actually the right way to go forward; for all we know it might just be an effective theory where the more fundamental theory has to be quantized instead), we cannot know for sure whether the ultimately successful theory of quantum
What is the relationship between a gravitational wave and a graviton? the graviton is a hypothetical elementary particle I understand that relativity and quantum mechanics are not well integrated, and that this gravitational wave is a macro-scale phenomenon that, experimentally, doesn't have much to do with particles
quantum gravity - What do gravitons do? - Physics Stack Exchange In quantum field theory, one constructs fields from representations of the Poincare group The Poincare group has a rotation subgroup, so the fields have certain transformation properties under rotations, which we refer loosely to as the particle's spin From this viewpoint, the graviton is the unique particle that has zero mass and spin 2
