(+) Yeah! (+)

Particle colliders can create antimatter as a result of particle collision.
Annihilation creates a ridiculous amount of energy proportional to the mass annihilated.
Given these facts, could a particle collider create enough antimatter that the annihilation of that antimatter could power the particle collider to create more antimatter, and so on? Would that solve the problem of energy generation?

idk but you'd still have to harness the energy and put it to practical use. Which means storing it in something and transporting it to where it needs to go.

tl;dr: Can I perpetual motion?

No, you'll eventually run out of matter.

Oh, I see. I read it wrong.

I don't know enough about how these work to give a complete answer but here's a thought at least:

Each iteration through the process requires a certain amount of energy and a certain amount of fuel, and produces a certain amount of energy and certain amoint of waste. The process can continue as long as one iteration produces more energy than it consumes, plus enough to cover losses due to friction, sound or what have you.

Theoretically, but you'd never gain any net energy: all you'd end up doing is creating a closed system that oscillates between photons and leptons.

Another physics question, could simple harmonic motion be achieved between two magnets?

Hm. Maybe. I'm a little rusty on.my physics, but I'll take a stab at it.

If one magnet were really strong and really far away and the other were tied to a pendulum or a spring, then yes, I would expect so.

Simple harmonic motion is defined by x''(t) = -kx, while magnetic force varies inversely with r^2, so at close proximities you could have some sort of oscillation but it would be more complex. Technically speaking, even at great distances the sitution would only be approximatable as SHM, but this is the case with a gravitational pendulum/spring system too.

Looking at the mass-energy equivalence, it appears that almost all of the matter would have to be converted to antimatter, which is something that I'm pretty sure just doesn't happen. Oh well.

You could probably rig something up with rare-earth magnets and bismuth.
