oh so it will take a long time for protons to decay and the universe go back to a soup of subatomic particles (this time the soup is cold). then the black holes take over because these abnormalities don't care about atomic structures, as long as it got mass or energy it's gonna be eaten

how will it become a white dwarf during proton decay? isn't that the phase when all stars die?

do all neutron stars collapse into a black hole?

have you tried heavy water (D2O)? it's expensive as fuck and impractical but it would be interesting to see the results
