Consider dropping a Professor with an estimated mass of 80 kg from a safe, large distance, onto a SMBH with a mass of 10^7M⊙. The Prof makes an impact at the Schwarzschild radius, whereby he converts all of the gained kinetic energy into radiation with a 100% efficiency. Estimate this amount of energy, and express the result in the units of 1-MT hydrogen bombs; one of those releases about 4×10^22erg if dropped carelessly. Neglect the relativistic effects.
