Well we all know what’s going to happen with the science part. There going to make a black hole that dissipates in a short second...nothing is going to destroy earth... but what about all those people that believe god created everything??? Anger? Fear? The fact that their whole belief is wrong. That’s what im more worried about then a black hole destroying the earth...the over all out come is what I fear. .

His comments pretty much reflect what I want to know. Essentially: 1. Is there a theoretical reason that the possibility of the LHC creating a stable microscopic blackhole is ridiculously tiny? Or is it just simply outside of scientific understanding at this point to put a probability on it. And 2. If there is a non ridiculous possibility (say greater than one in a million over the projected life of the LHC) of a stable microscopic blackhole being formed and falling into an orbit around Earth's center of mass, why is this not a horrible scenario? It seems to me it would grow exponentially pretty quickly if it was stable. I am not anti-science in the least. I am excited about the LHC. I just want someone in the know to address these questions, which seem to be beneath scientists to address, but over the heads of folks who create science media for laymen.

However, their reasons keep evaporating. In 1999, the reason was that black hole formation required energy beyond the reach of any collider. Then the multiple dimension people began predicting creation of black holes at colliders. I concede that their theories are speculative, but when there are multiple published papers with more or less reasonable theories, we have to assign at least a small probability to the possibility that they may be true. In 2003 the reason not to worry was Hawking radiation. Then published papers pointed out problems with the fundamental theory behind Hawking radiation. This does not prove that Hawking radiation will not work, but again we must assign some reasonable probability to that possibility. Now an analogy between colliders and cosmic rays is supposed to demonstrate safety. Collider opponents have pointed out ways in which that analogy is inexact. You can assume that they must be wrong, but Michelangelo Mangano, a member of CERN's Large Hadron Collider Safety Analysis Group, at a recent talk at Berkeley, discussed problems with using "cosmic rays hitting the Earth" to rule out black holes and agreed with many of the points made by collider opponents. If you want to say that colliders are safe, it seems appropriate to have good reasons for saying so. Mangano's group will issue a report soon. Let us hope that they have good reasons this time.

Singularities cannot form in present day space-time, gravitational collapse occurs before a singularity can form. The horizon that then forms has to take on the role as singularity (much time after initial collapse and after one hell of a ride for the object that created it). Then a 2 brane forms across the diameter of the horizon which is opaque, this is mirrored on the outside of the horizon which forms a 3 brane (but its still really a 2 brane) in different degrees of transparency, which is naked but still has an horizon. Only the object that created it can see the information that’s leaving this brane, as it flows out unobserved by any other object. The whole thing will then evaporate into space creating a single massive potential for the object that created it, if the object is not observed in its full potential a real super nova will occur.
