We consider generic linear perturbations of a nonbidiagonal class of static black-hole solutions in massive gravity. |
Black holes could therefore be the vehicle for a kind of cosmic natural selection, in which universes are reproductively favoured if they make lots of black-hole offspring. |
Neither the white-dwarf theory nor the the black-hole theory can explain the presence of sulfur in the lake of fire, if it is to be taken literally. |
