AGH I know I will probably get thumbed down like last time I said this but E=mc^2 is NOT the theory of relativity. E^2=m^2c^4+p^2c^2 is. p is the momentum of the object, so if the object isn't moving (as in no kinetic energy at all), then yes E=mc^2 but otherwise, it is that equation I said above.
Also there is no known "still" object, unless you are talking in a specific frame of reference such as looking at a sample of atoms, but even then there is most likely some kinetic energy going on.

I'm suddenly reminded of how much I have forgotten since high school and college.

Actually, mass that enters a black hole is not lost. Black holes emit radiation. Over time, as a black hole's mass is converted to radiation, it evaporates. So essentially, whatever goes in a black hole is slowly released back into the universe.
Whenever there's a Science based post on FJ everyone suddenly turns into physics major. Even when we know that you quickly looked it up before commenting.
