I posit that at some critical mass such as the mass of this Universe, a black hole would convert all its matter into virtually massless particles such as neutrinos, gamma rays, etc. thereby eliminating almost all gravity and essentially exploding.

Anyone know of theoretical research along these lines?


Energy, like its mass equivalent, contributes to gravity.
