Annihilation of antimatter meteors

  • P. M. Papaelias


Antimatter meteors probably enter the Earth's atmosphere. If they have the ability to escape complete vaporization during their infall flight, it may be possible, that a fraction of their original mass could survive for short or long time, depending on the mechanisms of ablation. In case of ablation through the annihilation process only, the lifetimeδτ of such an object is following the simple relationδτ = (N L )/(rA), whereδ andA are the density and the atomic weight of the antimatter fragment respectively,R is its radius,r is the rate of annihilation per cm2 of its surface, and N L is the Loschmidt number.
