Hawking radiation. A black hole emits hawking radiation at a wavelength about equal to its diameter, and with power (ie energy/time) inversely proportional to its diameter. So the smaller the black hole, the higher the energy of the

You seem to already know this, but "Metabolism First" is the name used for the theory in biology that you just described[0] The idea is that some self-catalyzing cycle(s) of reactions among chemicals structurally much simpler tha
