Hydrogen result causes controversy

It always makes me marvel when I disregard a particular fringe idea, and then it comes back and bites me. I never considered the hydrino hypothesis very much, never enough to decide yea or nay. But it appears to have some new life breathed into it.

The idea is this: when electrons in atoms drop an energy level, they give off energy. The suggestion was that perhaps, you could get the electron in hydrogen, the simplist atom, to drop a level below ground state, its lowest state. That should be impossible.... shouldn't it? Scientists are generally agreed it is just silly... but reasons so far are a bit weak. Time for me to pull my Quantum text out.
