The LHC can supposedly produce collisions with energy of around 7x10^12 eV. The hightest ultra-high energy cosmic rays, however, are around 3x10^20 eV. That gives cosmic rays, which have been hitting the earth for billions of years, about 40 billion times the energy that the LHC can produce. So far, no earth-gobbling black holes. Another thing, collisions at very near the speed of light produce secondary particles also travelling near the speed of light. So any black holes created as a result would fly through the earth and into space in less than a second. Thirdly, there Hawking radiation. A black hole of such low mass would evaporate in a nano-second at most.
That would be 40 million I mean.
Theorhetically mini black holes are produced naturally all the time but they dissipate in nanoseconds. As I understand it, black holes require a certain ammount of mass for them to be sustained.
How unusual. A little wisdom on a science thread for a change.
Thank you very much.
