Black hole immunity theorem and dark matter
  We prove that the primordial black holes in the early universe did not decay until the gravity decoupled from the other interactions. Rabinowitz' two objections to the formation of Holeums are shown to be inapplicable. We show that primordial black holes having masses beween 8x10^18 GeV and 10^19 GeV formed gravitational bound states called Holeums when the temperature of the universe was between 10^30 K and 10^29 K. We prove that the black holes in a fire ball produced in an accelerator such as the LHC, modified into an inertial confinement type set up, will not emit Hawking radiation as long as the fire ball is maintained in thermal equilibrium or is allowed to expand adiabatically.
