Forceman Yeh, but these holes are extremal. That means they do not electroradiate away any energy. What i would like to ask is if the electron is a black hole, wouldn't we notice visible temperatures that are very high? Black Holes have no upper limit. They can be as big as nature wishes. But the smallest black hole must be in accordance with the Planck Mass given as: \((hc/2piG)1/2\) Where h is Planck's Constant, c is the speed of light and G is the Gravitational Constant. Mini black holes seem to be the best chance for scientists. There is simply no way we could create a minimum sized hole with a mass of about 22 micrograms because we would need about \(10^{16}\) TeV just to produce it, which is many magnitudes higher than we can produce today. A mini black hole would have a radius of about \(2 x 10^{-19}m\) – very small – with a very large temperature of \(1.5 x 10^{14}K\), or about 25 billion times hotter than the Sun!

OK, Then what would the residual result be, from fragmented light units having decayed into liquid electricity, which evaporated in air..?
