Graviton| Graviton |
In General > s.a. cosmological
constant [fat];
gravitational radiation; low-spin
field theories; quantum field theory
in curved spacetime.
* Idea: Classically,
a solution of the wave equation obtained linearizing the Einstein equation;
In
quantum theory, a quantum of the spin-2 field obtained linearizing
gravity.
* Reality and detection:
Freeman Dyson has questioned whether any conceivable experiment in the real universe
can detect a single graviton; If not, is it meaningful to talk about gravitons
as physical entities?
