I was pulling off some duct tape (black Gorilla tape) from the side of my stand-alone air-conditioner unit in the dark. Although stuck on well, the tape was fresh and came off cleanly from the plastic outer cover. During separation, at the point of separation, a blue light was emitted. I repeated...

So far I have come to know that changing magnetic field (or flux) creates current. This is also known as Faraday's law of electromagnetic induction. The direction of the current is opposite to the change occurring in the circuit. But why is the current induced at the atomic level? I don't want to...

Since Quantum Field Theory can't handle gravity, and gravity is mathematically equivalent to acceleration (equivalence principle), does this mean Quantum Field theory can't handle accelerated frames of reference?
