MATTER AND ANTIMATTER
Copyright 1984 to 2003 Allen C. Goodrich
The Cambridge Encyclopedia of Astronomy quotes Stephen Hawking-
" Matter-antimatter pairs of particles are continually being produced
throughout space even in a perfect ' vacuum.'. This may be considered
a concequence of a variant of the Uncertainty Principle; large amounts
of energy are available for proportionally brief periods of time. This energy
may be sufficient to create an electron-positron pair,say, which then
annihilates almost immediately. The net effect is nothing produced from
nothing. In the extreme gravitational environment close to the
Schwarschild Radius of a black hole, one of the newly-created particles
may be dragged within the black hole. This time the net effect is a free
particle outside the hole. We cannot get something for nothing however,
and the black hole decreases in mass by an amount proportional to the
mass and energy of the free particle. In this way a black hole evaproates
away its rest mass energy.".
This theory requires that one of the particles , say the positron , is an
antimass which would subtract from the mass of the black hole and
result in an evaporation or decrease in the mass-energy of the black
hole.
In an expanding universe of constant total energy, as predicted by the
first law of thermodynamics, the expansion of the universe relative to
mass, with the resulting decrease of potential energy, say equal to
the energy of a high energy gamma ray, would result in the formation
of an electron-positron pair of equal total kinetic energy. This is necessary
to conservwe the total energy of the universe. Although the
positron is a positive charge and the electron is a negative charge,
their total energy is positive and equal to the total energy of the high
energy gamma ray that they replaced.. No reduction of the total energy
of the black hole would result from the acquisition of a positron.
( as the first law of thermodyanmics requires ).
