I like your ideas in the 3rd paragraph, concerning slow and stable micro black holes. Other orbits could be thinkable too, for example in a galaxy but who could calculate it?

Here is my response. Sorry for delay, I have seen your message just now.

Yes there are more than 7 other planets, many asteroides, the sun and so on — but natural (stable or metastable) micro black holes that are formed on celestial bodies are very fast in respect to their birth place, so they would probably just fly through it, if they are uncharged and if their (initial) growth rate is small enough.
It is possible that all naturally formed micro black holes have been fast enough, to escape the solar system since its existence.
Just stable micro black holes that would be formed by frontal collisions, in which both collision partners would have almost the same speed relative to reachable celestial bodies, could cause some danger. But such high energetic “LHC-like” frontal collisions are very rare, and the distance between celestial bodies is very long. CERN should be neutral and make some fair calculations in respect to such arguments.

If we do not know every possible (stable or metastable) exotic particle (not just micro black holes) and if we do not know their lifetime, their conditions of origin and their reactivity under different conditions and velocities and if we do not consider all possible(!) differences between cosmic ray collisions and collisions at the LHC, then we can not tell whether the LHC is safe or not.
An other point is that cosmic ray protons with 14TeV or greater have never directly observed, just the secondary ray showers have been observed. Who knows whether the very rare cosmic ray “events” with 14TeV or greater are protons ?

Thank you for discussion.

Whether the black holes were entrapped by the Earth is irrelevant — there are seven other planets and the Sun — any black holes entrapped by these bodies would have caused them to collapse by now…

What about collisions slow enough to be entrapped by the Sun…since they don’t evaporate, these black holes would still be in the solar system, orbiting the Sun, if they were formed moving slower than the solar escape velocity at formation distance from the Sun (i.e. 16 miles per second or slower within Earth’s orbit, any time since the Sun formed?

And what about the select fraction moving slow enough that their orbits actually intersect the sun itself (albeit a small fraction, but still probably a few in the history of the Solar System? After a number of passes through the sun, in a wide elliptical orbit, the mass would grow, and the hole’s orbit would eventually wind up within the Sun.

How many black holes fitting these conditions would have been formed since the Solar System was formed?

And what about stars that expand into red giants, engulfing any black holes in orbit around them?

CERN and their (own) safety group LSAG say that all what happens at CERN does happen naturally on Earth too. They say that since the existence of the planet nature has conducted about hundred thousand entire LHC-experiments and the Earth does still exist. After that they tell how many LHC-experiments have been conducted at the sun, then in the Milky Way and then in the Universe. See LSAG report, page 4.

I have read the LSAG report and counted the comparisons of cosmic ray collisions with ‘LHC experiments‘ over 14 times, then I gave up. It is also interestant that they like to refer to it, each time if they have no closing proof of safety. Is it usual in science to research such catastrophic risks (the destruction of earth or in case of false vacuum the destruction of the entire Universe) like this ?
How rare are the naturally formed Micro Black Holes ? Nobody knows. CERN does even not know at what energy they will be formed. I have asked a Physics Professor who is working there. If we would know at what energy they will be formed then we could make a calculation with all necessary parameters and factors, for example the shadow of Earth, the direction and the velocity of the particles, the gravity, etc.
MAC has once made a calculation concerning the theme and Marc Fasnacht has made the conclusion of 0,000’000’0045 natural collisions would have resulted in a Micro Black Hole, since the existence of Earth, slow enough to be entrapped on Earth. This is very probable not a single one…!

We are talking about infinitely stable, uncharged Micro Black Holes (MBH), which could just be detected via loss of energy — but what about metastable Micro Black Holes or other (possibly dangerous) exotic particles ? Probably it depends on their lifetime, on their reactivity, on their speed in respect to celestial bodies and similar aspects. I am thinking for example about the “moderator” in nuclear reactors. It is for slowing down the particles. Too fast particles would not react with the fuel of the reactor. In some cases, various speeds can mean various reactivities.
It is perhaps not the same too, whether collisions take place high in the atmosphere or at the surface of Earth.
I am not sure whether the calculation of MAC and Marc is right or not but I am pretty sure that nature has not yet collided pairs of nearly equal fast protons or lead ions, head-on, 20 centimeters or less above the surface of celestial bodies in our entire milky way ! Just CERN does it.
Calculations of CERN / LSAG (see link, page 4) are just in respect to fast cosmic rays hitting slow atoms of Earth and that will result in fast MBH, probably going through Earth and leaving it again. Higher energies result in faster MBHs.
The ‘density‘ resp. luminosity of the particle beam is an other difference between nature and the LHC — but CERN / LSAG ignores such facts and say that “exactly the same” would happen on Earth, which is untrue…

Thanks to all for their interest and sorry if my English is bad.

Would be very interested in seeing a paper on this topic.
