Could a supercollider create a black hole that sucks up the earth?

Supercolliders are machines designed by physicists to accelerate particles close to the speed of light, smash them, and then observe the effects to learn more about the fundamental nature of the universe. The energy created in these collisions may be sufficiently high to create black holes.

CERN counters that if the hoped-for mini black holes are stable as claimed, equal stable particles must arise naturally by ultra-fast cosmic-ray protons colliding with planet bound protons. This is correct. However, there remains a fundamental difference: Only the man-made ones are “symmetrically generated” and hence dangerous. For they alone are slow enough with respect to the earth that one of them (at less than 11 km/sec) can take residence...

This physical realm is unknown, and dangerous phenomena might arise… Any physicist will tell you that there is no way to prove that generated black holes will decay. The consequences of being mistaken are unfathomable. This subject deserves serious unbiased discussion.

Concerns have been raised in three general categories: a) Formation of a black hole or gravitational singularity that accretes ordinary matter, b) Initiation of a transition to a lower vacuum state, c) Formation of a stable strangelet" that accretes ordinary matter. Our conclusion is that the candidate mechanisms for catastrophe scenarios at the RHIC are firmly excluded by existing empirical evidence, compelling theoretical arguments, or both. [note: the RHI Collider went operational in 2000]

The size of these black holes is too small, and their life span too short, to pose any threat... similar black holes are created organically every day when cosmic rays smash into the earth’s atmosphere at even higher energies than those found in particle accelerators.

The Large Hadron Collider can achieve an energy that no other particle accelerators have reached before, but Nature routinely produces higher energies in cosmic-ray collisions. Concerns about the safety of whatever may be created in such high-energy particle collisions have been addressed for many years. In the light of new experimental data and theoretical understanding, the LSAG has updated a review of the analysis made in 2003 by the LHC Safety Study Group, a group of independent scientists.

Rössler argues that he is able to conclude, based on his reinterpretation of the Schwarzschild metric, that Black Holes do not emit Hawking radiation [hypothesized by Steven Hawking] and will thus exist forever. Therefore, if produced at the LHC, they would represent a serious danger: instead of decaying by radiation, they would exist eternally and would have sufficient time to gradually devour their environment. ... We will see that his argument is not valid ...

The safety of collisions at the Large Hadron Collider (LHC) was studied in 2003 by the LHC Safety Study Group, who concluded that they presented no danger. Here we review their 2003 analysis ... which enable us to confirm, update and extend [their] conclusions... The LHC reproduces in the laboratory, under controlled conditions, collisions at centre-of-mass energies, less than those reached in the atmosphere by some of the cosmic rays that have been bombarding the Earth for billions of years.

To create a black hole which could suck up the earth, we'd have to basically implode our sun or something. Hmmmmm, we're good but not that good. Anyway, sounds like these momentary black holes which we predict will be created, will last less than a second before they're gone.

I've been unable to find a single particle physicist who will answer anything other than "disagree". Professor Otto Rössler is not himself a particle physicist, and the basis for his arguments has been refuted by Professor Domenico Giulini and Professor Hermann Nicolai of the Max-Planck-Institute for Gravitational Physics at Golm.
