The physics of the Sun involves all possible physical processes and ye
ar after year forgotten processes are taken into account. A brief and
partial history of recent dealing with gravity waves is presented here
. There are random motions in the solar convective zone. They generate
, at the boundary of the convective zone, gravity waves which propagat
e in the radiative zone. Random gravity waves generate three physical
processes: (1) diffusion induced by the stochastic properties of rando
m gravity waves; (2) transport of angular momentum; (3) influence of n
onlinear properties on the rate of thermonuclear energy production. Ta
king into account processes (1) and (3) can possibly lead to the solut
ion of the solar neutrino problem.
