Graviton

In theories of quantum gravity, the graviton is the hypothetical quantum of gravity, an elementary particle that mediates the force of gravitational interaction. There is no complete quantum field theory of gravitons due to an outstanding mathematical problem with renormalization in general relativity. In string theory, believed by some to be a consistent theory of quantum gravity, the graviton is a massless state of a fundamental string.

If it exists, the graviton is expected to be massless because the gravitational force has a very long range, and appears to propagate at the speed of light. The graviton must be a spin-2 boson because the source of gravitation is the stress–energy tensor, a second-order tensor (compared with electromagnetism's spin-1 photon, the source of which is the four-current, a first-order tensor). Additionally, it can be shown that any massless spin-2 field would give rise to a force indistinguishable from gravitation, because a massless spin-2 field would couple to the stress–energy tensor in the same way that gravitational interactions do. This result suggests that, if a massless spin-2 particle is discovered, it must be the graviton.

1. Laughlin, who received a Nobel Prize in Physics, shows us in his important, brain–tickling new book, ‘‘A Different Universe.‘‘ Like the blacksmith to whom everything resembles a nail, some physicists spent decades trying to explain everything in terms of particles; thus, gravity was attributed to a hypothetical ‘‘graviton.‘‘ In recent decades, though, a few physicists have won acclaim for experiments with antireductionist implications.
2. In Our Time Technically more weird than awful, Melvyn Bragg wraps his intellectual jowls around ginormous and baffling subjects as dementedly diverse as "The Graviton – the quest for the theoretical gravity particle", "Greyfriars and Blackfriars – philosophy, evangelism and fund–raising in the 13th–century Church" or "Pastoral literature – the romantic idealisation of the countryside". It‘s like being locked in a university library with several tutors.
