I'd check your credit report to see if anything from them or the university appears. If the school can't give you direct info and the agency can't give you more information than "you owe us money" I'd assume its fraudulent and dispute the charge with the credit agency if it appears at all. Does the guy on the phone have an accent? Sounds scammy to me.

Looking at it like the multiverse splitting with ever decision seems a little anthropomorphic to me. I'm certainly not a physicist but I figure it's closer to how quantum uncertainty works, like an electroc being theoretically anywhere in a certain energy level around an electron. So you've got all this quantum soup sploshing around and we only really observe one possible configuration of it. Maybe all of the others possible exist at the same time, but only one is our "real" universe because that's what we observe.

Renewable might not be the right word really. Think of it in terms of when an energy source will run out. Take a disposable battery. You get an hour or two of running something small, and then it's empty. Plus it took work on our part to put the energy into the battery. Now think about the sun. Technically it will run out of energy in billions of years, but for our life spans there's an infinite supply of energy, and we don't really have to do anything to cause the sun to provide energy (aside from devising ways to collect it). So renewable energy would be a source of energy that is going to keep producing without us doing anything to make that source produce. We don't have to do anything to make the wind blow, or waves move, or the insides of the Earth hot. So if we collect energy from those sources it will renew itself.
