Do gravitons self interact?
Do gravitons self interact?
Gravitons have self-interactions in any theory which reduces to Einstein gravity at low energies; the Einstein Hilbert action is not quadratic.
Do gravitons have energy?
Gravitons do indeed have mass, and their motions generate kinetic energy. Thus, they have both energy and mass, and they obey the law of conservation of energy and matter. If gravitons did not have mass there would be no physics that we could understand.
Has the existence of gravitons been proven?
The graviton remains hypothetical, however, because at the moment, it’s impossible to detect. Although gravity on a planetary scale is strong, on a small scales it can be very feeble. So much so that when a magnet attracts a paperclip, it pulls against the gravitational force of the entire planet, and still wins.
What force do gravitons carry?
Gravitons are thought to carry the force of gravity in a way that’s similar to how photons carry the electromagnetic force.
Can gravitons interact with photons?
The answer to your question is by no means a solution to the “graviton mystery”, but assuming gravitons exist, yes, undoubtedly they interact with photons. The idea of gravitation (and by extension, quantum gravity) is that the tensor field of gravitation couples to all other fields universally and minimally.
Is the Higgs boson a graviton?
The graviton is the carrier of the gravitional force if you describe that force by a quantum field theory. Whether gravitons are a useful way to describe quantum gravity is not clear. However, what is clear is that the graviton and Higgs boson are entirely unrelated.
Why does gravity bend light?
The presence of matter curves space, and the path of a light ray will be deflected as a result. This process is called gravitational lensing because of its similarity to the way normal lenses bend light rays that pass through them. Einstein predicted that light rays would be bent by the gravity of massive objects.
Is there an anti graviton?
An anti-graviton, if it existed, would have the identical properties of the graviton. No existing experiment has proved conclusively that these particles exist but improvements to current detectors such as VIRGO and LIGO should be up and running within a year or so.
How does light create gravity?
Light has energy, energy is equivalent to mass, and mass exerts gravitational force. Thus, light creates gravity, i.e. the bending of space-time. Thus, in order for the light to generate a gravitational field like that of the Earth, it would need to have the mass (energy) of the Earth.
