CHAPTER 12: QUANTUM GRAVITY

New Physics and the Mind - Quantum Gravity

Under general relativity theory, which is a classical not a quantum
theory, the force of gravity is propagated by gravitational waves,
which transmit the force of gravity at the speed of light.

Under
a quantum theory of gravity, we focus on the quanta of
gravity—gravitons, the elementary force particles that transmit gravity
through a process of graviton exchange. Gravitons, never experimentally
observed, are particles of zero mass which travel at the speed of light
and have a quantum “spin” of 2.
