"In a dismissal that underlines his firm rejection of religious comforts, Britain's most eminent scientist said there was nothing beyond the moment when the brain flickers for the final time."Well, the good news is that Hawking did not dismiss the existence of the Tooth Fairy or Santa Claus.
But why didn't Hawking explicitly dismiss the existence of Hell? What if there's no Heaven but only a Hell? What if everyone goes to Hell? No, wait, that will make Hell just like earth, except with better heating and more interesting roommates.
