Someone's trying to break the universe again. The wish-granting genie lists standard prohibitions: no death wishes, no love spells, no necromancy. Then comes the physicist with "make protons heavier than neutrons" and suddenly there's a fourth rule. Fun fact: neutrons are actually about 0.14% heavier than protons, which is why free neutrons decay into protons in about 15 minutes. If protons were heavier? Stars wouldn't form, atoms would collapse, and chemistry as we know it would cease to exist. But sure, go ahead and ask the genie to rewrite fundamental physics. Some people just want to watch the world literally disintegrate.
