The CERN Scientific Policy Committee (SPC) was asked by the President of the CERN Council to examine the documents produced by the LHC Safety Assessment Group (LSAG) and to provide Council with an independent opinion on the conclusions stated in those documents. Their stamp of approval is contained in the document SPC REPORT ON LSAG DOCUMENTS. The report has not been externally validated, but the report has been released so that the world’s scientists are now able to critically review and validate this report.
Quote from the SPC committee: “A powerful argument applicable also to higher energies is formulated making reference to observed neutron stars, but this argument relies on properties of cosmic rays and neutrinos that, while highly plausible, do require confirmation, as can be expected in the coming years.”
The SPC committee does not appear to recommend delaying high energy collisions at the Large Hadron Collider until after these safety theories can be confirmed.
The new report argues that when a stray cosmic ray matter particle collides with Earth or a Neutron star, dangerous black holes are not produced.
The report confirms that neutral micro black holes that might be created from cosmic ray impacts with Earth would exit Earth at near the speed of light. And Dr. Otto Rossler appears to argue that a micro black hole should be neutral unless it captures a charged particle such as an electron in orbit around the micro black hole. Capturing a charged particle in orbit around the black hole appears unlikely to be possible while traveling through Earth at relativistic speeds, and might not be possible in a Neutron star.
The Safety Report appears to argue that a micro black hole could become charged by consuming charged quarks, but that might be a controversial assertion, since once matter passes the event horizon of a black hole, it should no longer have effects outside of the event horizon, so the black hole should remain neutral.
The safety report also asks us to accept what appears to me to be a questionable assumption, that a cosmic ray particle collision with Earth must produce a micro black hole if any possible collider collisions might produce one.
“cosmic rays do not produce such [dangerous] black holes, and hence neither will the LHC“.
The report appears to require that a single cosmic ray particle impact with Earth or a Neutron star must produce the same results as any possible collider conditions, including colliding thousands of tightly packed protons and Lead to Lead nuclei head on at 99.9999991% of the speed of light with powerful magnets to focus the energy and exactly opposing momentums that might create dangerous black holes at rest with respect to Earth.
The LHC may create for the first time on Earth, slow moving micro black holes that might be captured by Earth’s gravity, and since evaporation (Hawking Radiation) is disputed, and fast growth of charged micro black holes is predicted, I am still concerned, and very interested in what the world’s scientists will conclude after studying this report in detail.
