Both say only correct things. What Ed did not take into regard is the delay until a miniblack hole coasting through matter hits the first quark. So his request for numbers is justified. Only that no one on the planet can give the numbers since no one can possibly know the radius of a successfully formed miniblack hole. Nevertheless the qualitative argument that any perpetual coasting inside earth will eventually lead to an almost head-on hit is inescapable. It can be weeks, or, if we are lucky, up to years.

How long it thereafter takes until the charge has been eaten (and hence nullified) is another open quantitative question. It is related to the question of how long it takes an element in the accretion disk of a quasar to fall in eventually. Since the involved electric forces now are billions over billions times higher than the gravitational one taken alone, and all the complexities of multi-particle interaction, etc., enter, very soon a new field of complexity theory (I call it minimini-quasar theory) is involved. It will be very interesting to develop this field. But to exclude the likely formation of an “animal” (an attractor with distinct properties) would be over-optimistic. It is this overoptimistic clairvoyance which must be avoided. It cannot be assumed that the remaining uncertainty would detract from the danger.

The unknown features of quasars and miniminiquasars are a wonderful scenario for exact quantitative calculations again — but so only in the more or less distant future.

Real risk from black holes depends on them not being able to be charged. If mini black holes can be charged, and can be easily generated, then the cosmic ray arguments apply, since charged black holes will be very effectively stopped by matter such as stars.…leading to accretion of the stars (or White Dwarfs) if they don’t evaporate!

Cosmic ray arguments are only invalid if black holes cannot be charged. Otherwise, they prove the LHC is safe from a threat of black holes, no matter what the rate of accretion or lack of Hawking radiation.

As far as Plaga’s concern with “Bose Novas,” his paper was rebutted, and he still has not responded. It is up to Plaga to respond…out of my pay grade.

As far as strangelets go, they would be charged, or able to temporarily acquire a charge even if formed neutral, and hence would be stopped by matter. They would also affect stars, leading to faster supernovae (probably a lot of strangelets would get incorporated into forming stars if they exist), an effect which has not been seen (I don’t remember the location of the reference, or I would supply a link). Therefore, I do not consider strangelets a plausible risk. Or am I wrong? Are strangelets (if they exist) inherently uncharged and fast moving?

You might also think that Rossler’s “micro quasars” would acquire a charge as soon as they hit an atom passing through a star…leading to self-organizing chaos whirlpools… hence would be stopped…to me, this kind of seems like it would indicate that the cosmic ray safety arguments apply to even Rossler’s uncharged mini black holes. Rossler says these black holes would go right through matter, but he also says they form mini-quasars, which wouold probably get stopped by matter pretty easily, as soon as they hit just one atom going through a star!!

Black holes according to Telemach are uncharged…but micro quasars are charged. This, to me, seems to modify the whole thing completely. I’d like to see someone do the math on this…you’d think this possible conclusion from Telemach would prove the cosmic ray arguments safe after all…or am I wrong? I’d sure like to see the numbers!!!!!

Helfer and Vilkovski theorize that Hawking Radiation is only partial…but I can’t figure out why this partial Hawking radiation would not have been seen in CERN’s search for black hole evaporation (Robert Houston claimed that CERN ‘s search was only set up to see complete evaporation, but I just can’t see how this would be correct — radiation is radiation!).

And if these black holes fitting Vilkovski’s theory are correct, they would still be charged, and would be stopped by stars anyway…and therefore would be unlikely to be a threat unless they could not hold a charge.
