Hmmm... new one to me, but I haven't studied that much quantum theory. This seems to run contrary to relativity, could you elaborate?

Keep in mind, it's hard to get Relativity and Quantum to agree. We still haven't reached a working theory of quantum gravity (not one that predicts anything new, anyway)

True true.

I did some more research on this, and if I think about it, it makes sense that a positron would be an electron moving backwards in time. This would provide an easy explanation for annihilation, i.e. intersecting world-lines.
What I can't get though is how equal amounts of anti-matter and matter could have been created in the big bang then. Obviously the anti-matter couldn't have moved back in time before the big bang. So what accounts for the natural presence of anti-matter in the universe since then?
What am I missing?

They agree on everything but gravity. The dirac equation is the relativistic form of the schroedinger equation.

Yes, and it's what gave rise to the negative energy solutions and the idea that positrons are electrons moving backward in time (or that they're negative energy electrons.

Gravity is a pretty BIG point of contention

Ah, but we don't know if equal amounts of matter/antimatter were created in the big bang. We haven't been able to account for enough antimatter to believe that there are equal amounts of both. For some reason we see significantly more matter than antimatter in the known universe.

I'm not sure if we can say that a positron moving forward in time is actually an electron moving backwards in time. It definitely fits with the math, but it's hard to talk about.

Two atoms are walking down the street.

One says to the other,"I think I lost an electron."

"Are you sure?"

"I`m positive."

A positron is the anti-matter equivalent to an electron, i.e. it has a positive electric charge instead of a negative charge. Its mass is identical to that of an electron (1/1836th of a proton). A positron does not travel backwards in time.

Baryonic matter has electric charges that causes them to interact with other baryonic matter. The fundamental nature of our world is electromagnetic interactions, as the physical size of matter is actually so small that most physical objects that you see are actually 99% empty space, with these electromagnetic fields holding the matter we see apart and in alignment in order to produce the properties that we see in them.
Contrast this with dark matter with is believed to be matter with no electric charges, and thus does not interact except through gravity and bumping physically into other matter. As matter is so tiny though, it is believed that large numbers of non-interactive matter, like neutrinos, pass through the earth constantly without hitting even a single atom.
Anti-matter is identical to matter in every way except for the same particles having opposite electrical charges.

Actually OP is right. In quantum electrodynamics the math works out to be identical if you have positrons being electrons that go backwards in time.

This is quantum mechanics? What is quantum electrodynamics?

This book is a surprisingly easy read. Text

1.213984724 jW to be exact. You have to be careful which way the flux lines are cutting through the capacitor. If they are running parallel to the dielectric the temporal displacement will not be optimum and you will be vaporized.

A new element discovered:

Research has led to the discovery of the heaviest element yet known to
science. The new element, governmentium (Gv), has one neutron, 25
assistant neutrons, 88 deputy neutrons, and 198 assistant deputy
neutrons, giving it an atomic mass of 312.
These 312 particles are held together by forces called morons, which are
surrounded by vast quantities of lepton-like particles called peons.
Since Governmentium has no electrons, it is inert; however, it can be
detected, because it impedes every reaction with which it comes into
contact. A minute amount of Governmentium can cause a reaction that
would normally take less than a second to take from four days to four
years to complete.

Governmentium has a normal half-life of 2- 6 years. It does not decay,
but instead undergoes a reorganization in which a portion of the
assistant neutrons and deputy neutrons exchange places. In fact,
Governmentium's mass will actually increase over time, since each
reorganization will cause more morons to become neutrons, forming
isodopes. This characteristic of moron promotion leads some scientists
to believe that Governmentium is formed whenever morons reach a critical
concentration. This hypothetical quantity is referred to as critical morass.

When catalyzed with money, Governmentium becomes Administratium, an
element that radiates just as much energy as Governmentium since it has
half as many peons but twice as many morons.

That always cracks me up.

BTW OP in for more serious discussion, I have never heard this before, however my knowledge of quantum mechanics comes from late nights on wikipedia.

That about sums it up for me. Carry on.
