Jul 22, 2026
A-1 - A stated catastrophe probability is conditional on the argument's soundness and is dominated by argument-failure when very small
Jul 22, 2026
A-11 - Thermality criteria require black-hole masses several times the Planck scale, out of reach of near-threshold LHC production
Jul 22, 2026
A-12 - Collisional inelasticity leaves only a fraction of parton energy behind the horizon, cutting black-hole cross sections by orders of magnitude
Jul 22, 2026
A-13 - A measured 1.97-solar-mass neutron star bounds the maximum density of cold matter at about 4e15 g per cm3
Jul 22, 2026
A-14 - The measured E-half energy matches the parameter-insensitive GZK-proton prediction
Jul 22, 2026
A-15 - Kerr emission-rate calculation - spin-down precedes mass loss and rotation changes black-hole lifetime by at most a factor 2.7
Jul 22, 2026
A-16 - Declination-independence of the spectrum disfavors a few-source origin of the instep
Jul 22, 2026

Jul 22, 2026
A-22 - Orbital-decay agreement with GR excludes dipolar radiation and significant strong-field deviations for 2-solar-mass neutron stars
Jul 22, 2026
A-23 - E-half agreement identifies the break as the GZK cutoff independently of the source spectral index
Jul 22, 2026
A-24 - Nature has already run the LHC collision programme 1e31 times on bodies that still exist, bounding any collider disaster mechanism
Jul 22, 2026
A-25 - Cosmic-ray collisions would already have nucleated any vacuum bubble the LHC could - and a bubble expands regardless of production frame
Jul 22, 2026
A-26 - Dangerous magnetic monopoles are excluded - GUT monopoles are far too heavy for the LHC, and cosmic-ray-produced ones would have stopped in Earth harmlessly
Jul 22, 2026
A-27 - Hawking radiation, resting on consensus quantum theory in curved space, makes LHC micro black holes evaporate
Jul 22, 2026
A-28 - Whatever colliding partons can singly produce can decay back into them - black hole stability would violate quantum mechanics
Jul 22, 2026
A-29 - Stable black holes from cosmic rays would be charged, stop in Earth or Sun, and accumulate in billions - the absence of any effect excludes the scenario
Jul 22, 2026
A-3 - Weak-scale string tension is realizable only in type I string theory, with large extra dimensions from 0.1 fermi to 100 microns
Jul 22, 2026
A-30 - Even hypothetically stable neutral black holes would have destroyed observed white dwarfs and neutron stars - their survival closes the last case
Jul 22, 2026
A-32 - Lunar survival under billions of years of heavy-ion cosmic-ray collisions rules out dangerous strangelet production - RHIC data validate both assumptions
Jul 22, 2026
A-33 - Interstellar heavy-ion collisions would have seeded stars with strangelets - the absence of strangelet-triggered stellar explosions bounds the danger with no velocity assumption
Jul 22, 2026
A-34 - Replacing the collapse by past-horizon boundary conditions reproduces the Hawking flux
Jul 22, 2026
A-35 - Accelerated detectors respond thermally in vacuum while geodesic detectors near the horizon see no Hawking flux
Jul 22, 2026
A-36 - In a 2D model the computed Hawking outflow depends on the regularization - covariant fermion-boson cancellation gives zero
Jul 22, 2026
A-37 - Outgoing Hawking modes trace back to trans-Planckian frequencies at the horizon
Jul 22, 2026
A-38 - QFT on a collapsing-star background yields a thermal emission spectrum independent of collapse details
Jul 22, 2026
A-39 - A negative energy flux across the horizon forces mass loss and a finite lifetime of order 1e-28 M cubed seconds
Jul 22, 2026
A-4 - The warped two-brane metric solves Einstein's equations and yields the exponential hierarchy from krc of about 50
Jul 22, 2026
A-40 - Black-hole thermodynamics independently demands emission at exactly kappa over 2 pi
Jul 22, 2026
A-41 - Greybody-corrected numerical calculation fixes the evaporation power and its division among species
Jul 22, 2026
A-42 - Solar capture and catalysis kinematics convert the Super-K neutrino limit into a monopole-flux bound
Jul 22, 2026
A-43 - The 10^18.5 eV dip survives resolution, aperture, and epoch checks, so it is a real spectral feature
Jul 22, 2026
A-44 - Basic quantum principles imply LHC-scale black holes decay in about 1e-27 s - stability would need physics with no consistent framework
Jul 22, 2026
A-45 - Charged stable black holes would stop in Earth or the Sun, so their multi-billion-year survival excludes that scenario
Jul 22, 2026
A-46 - Neutral cosmic-ray-produced black holes punch through Earth and Sun, voiding the naive cosmic-ray safety argument
Jul 22, 2026
A-47 - For crossover radius below about 200 Angstrom a stable hole in Earth accretes far slower than the solar lifetime
Jul 22, 2026
A-48 - For crossover radius above about 200 Angstrom Earth accretion could be fast, so Earth-internal calculation alone cannot close the safety case
Jul 22, 2026
A-49 - Solar-mass white dwarfs provide enough column density to stop cosmic-ray-produced neutral black holes for D up to 7
Jul 22, 2026
A-5 - Absence of light KK modes exempts RS1 from the astrophysical and cosmological bounds on large extra dimensions
Jul 22, 2026
A-50 - Cosmic rays produce thousands of black holes on low-field white dwarfs within tens of millions of years under any composition
Jul 22, 2026
A-51 - White-dwarf survival excludes every scenario in which Earth accretion would be dangerous - the accretion-time ratio is about 2e4
Jul 22, 2026
A-52 - Neutron-star survival bounds the D of 8 and higher scenarios via binary beam dumps and cosmogenic neutrinos
Jul 22, 2026
A-53 - No Eddington limit throttles micro-black-hole accretion in Earth, white dwarfs, or neutron stars
Jul 22, 2026
A-54 - Conservative overestimates give k_cl = 1e-22 and k_qu = 1e-34 for RHIC - gravitational collapse is absurdly out of reach
Jul 22, 2026
A-55 - 1e47 comparable cosmic-ray collisions in our past light cone bound a RHIC-triggered vacuum transition below 2e-36
Jul 22, 2026
A-56 - A strangelet catastrophe requires four independent conditions, each judged unlikely - with no plausible route to the last two
Jul 22, 2026
A-57 - Stable strange matter is overwhelmingly likely positively charged - and a positive strangelet is harmless, its fusion Coulomb-suppressed to a rate of 1e-200000 per second
Jul 22, 2026
A-58 - Coalescence and thermal production models bound dangerous strangelet yield near 1e-46 per collision, peaking below AGS energies rather than at RHIC
Jul 22, 2026
A-59 - Lunar persistence bounds dangerous strangelet production at p below 2e-11 - unless production is confined to exactly central rapidity
Jul 22, 2026
A-6 - The vacuum-stability verdict hinges on the top-quark mass input and on assuming no new physics below the Planck scale
Jul 22, 2026
A-60 - Strangelets born in interstellar space would convert stars in supernova-like events - the observed supernova rate bounds RHIC danger below 2e-8, tightening to 1e-21 - unless strangelets are metastable
Jul 22, 2026
A-61 - Gauss law in 4+n dimensions ties a TeV fundamental scale to R of 1e30overn minus 17 cm - excluding n=1 and hiding n of 2 or more from all existing tests
Jul 22, 2026
A-62 - Graviton emission scales as ΔE to the n+2 over m_EW - so 1998 lab and astrophysical data fail to exclude TeV-scale gravity
Jul 22, 2026
A-63 - A nucleated true-vacuum bubble has zero total energy and expands at light speed, destroying the causal region with no warning
Jul 22, 2026
A-64 - Gravitational back-reaction suppresses decay to a negative-energy vacuum and quenches it entirely when epsilon is at or below 6 pi G sigma-squared
Jul 22, 2026
A-65 - If stable strange matter exists, nuclearites arrive at Earth as detectable cosmic radiation - nature is already running the exposure experiment
Jul 22, 2026
A-7 - Eddington-limited radiating micro black holes would be undetectable in white dwarfs and neutron stars, evading the astrophysical exclusion
Jul 22, 2026
A-8 - The white-dwarf stopping argument presumes semiclassical validity and fails for black holes below three times the Planck mass scale
Jul 22, 2026
A-9 - The allowed warping-length range up to 44 microns permits Casadio-Harms critical masses for which black-hole growth is catastrophic
