I might go straight to the proposal.   Consider that the interior of black holes (BH)s only contain negative energy densities, also known as negative masses. These negative masses have been predicted to be repulsive by other famous physicists such as H. Bondi and W. B. Bonnor, but have not been taken seriously due to a paradox called "runaway motion" which takes place between masses of different signs.    These negative masses would be created from infalling particles to the BH b
