Yes, that particular interaction is so and I said it ends up in a cloud of
gamma rays (photons). My statement that the positron is comprised of
anti-energy is incorrect; at the time I learned this, that was the agreed
understanding. More recent work has shown it is not so. However, Quantum
theory predicts that said photons will behave in a number of ways, including
popping out of existence or combining into electrons again. And none of this
denies the existence of negative energy.

Negative energy is a concept that is required by Quantum Mechanics and the
Uncertainty Principle.

A quick search shows the following links:

http://www.physics.hku.hk/~tboyce/sf/topics/wormhole/wormhole.html
http://www.physics.nmt.edu/~raymond/classes/ph13xbook/node150.html (this one
includes the Relativistic equation I quoted which forms the basis for the
deduction of negative energy)
http://jnaudin.free.fr/html/gsea21.htm
http://www.cheniere.org/references/negative%20energy.htm (this one bears out
my point regarding everything equating to zero)

I did not search or read any of the above before today, and did so only in
response ot your post.

My point in posting any of this was that it is possible to get something out
of nothing. In fact, the "something" "remembers" that it came from nothing,
and could be collapsed back into nothingness (at least, theoretically).

My proposition was that if all the energy and matter in the universe was
paired with it's anti-equivalent, the result would be zero. Oliver's
objection was that there is no such thing as negative energy; I think that
has been shown to be false, there is.

No, it doesn't mean that. But we certainly could be living in an imaginary
universe... :-)
