Graviton - Wikipedia, the free encyclopedia
In physics, the graviton is a hypothetical elementary particle that mediates the force of gravity in the framework of quantum field theory. If it exists, the graviton must be massless (because the g...

A theoretical particle having no mass and no charge that mediates (carries) the gravitational force. The graviton is a boson. ... The existence of a graviton has not yet been confirmed experimentally, although string theory predicts the existence of gravitons as closed strings with the minimum possible energy.

How come the graviton can escape the inner side of a black hole ? Since the space-time fabric inside a black hole makes everything move toward the center, gravitons should never escape, therefore black holes should not have a gravity field outside the horizon.

In a Perspective article for Science, he discusses the possibility that new experiments will shed clues about subatomic particles called gravitons and perhaps bring enough information to unite quantum mechanics and relativity, the two great theories rooted in the work of Albert Einstein.

These are not neccessarily gravitons just as light was not neccessarily seen as photons until high energy light such as X-rays were seen. (ie The X-rays act like small size particles sometimes more than they do as waves).

Ask the experts your physics and astronomy questions, read answer archive, and more. ... Is there any experimental data supporting the existence of gravitons? If there is, how fast do these wave/particles travel? Are they similar to photons? Asked by: John Shultz; Answer; Gravitons are indeed very similar in concept to photons.

The most recent Nobel prize in physics was given for the experiments that uncovered this evidence. The evidence comes from measuring the spin of an object called a "pulsar", which is supposed to be a spinning compact mass - a ... The pulsar orbits around a companion star that is nearby. ...
