Friends,
I'd like to see some numbers/critical facts here:
(1) Projected mass range of ultra-mini black holes,
(2) Dimensions of corresponding event horizon(s)
(3) Confinement method w/ safeguards
(4) Rate of evaporation in confinement, rate of
absorption in confinement, time to complete
evaporation in confinement
(5) Absorption characteristics--capture cross-section
w/quantum tunneling factored in--related to various
"absorbables" of different sorts:
(a) Garden variety matter, ie, protons,
neutrons, electrons,
(b) neutrinos
(c) photons, gravitons, magnetic monopoles,
gluons
(d) weird stuff that I would embarrass myself
trying to describe
(e) weirder stuff that professional physicists
would embarrass themselves trying to
describe
(6) Consequences of loss of confinement, ie,
characteristics of an ultra-mini black hole in free
fall towards the center of the earth, such as:
(a) mean free path between absorption events,
as a function of velocity,
(b) trajectory characteristics: absorption
event encounters will be "off-center", so
one might reasonably anticipate some
"scattering", plus some (+/-)
acceleration due to the energy
released in the absorption event.
(c) time to evaporation of BH, or, alternately,
time to absorption of entire planet, or,
alternately, time to explosive obliteration
of the planet due to sudden energy release.
(d) time between loss of containment and
realization of one possible solution to the
Fermi Paradox
Have a nice day.
Best, Jeff Davis
