In genetically susceptible humans, one of the proteins in H1N1 triggers an autoimmune attack by T cells against specific brain cells, and those brain cells dying causes narcolepsy.

Most flu vaccines by happenstance never included that protein. The vaccine that caused narcolepsy in susceptible people included the triggering protein.

Hawking radiation just appears (poof), it doesn't actually cross the event horizon.

Outside the event horizon, sure.

Inside the event horizon, space is warped in such a way that the only paths going towards the event horizon are in the past. Going forward in time, all possible paths go closer to the singularity.

Reply to comment by PoLoMoTo in ELI5 why do electric vehicles have one big battery that's hard to replace once it's expired, rather than lots of smaller ones that could be swapped out based on need (to trade off range/power/weight)? by ginonofalg

Rich Rebuilds had an episode like this. The car featured there was not very old.

Reply to comment by bstabens in Is it possible for two planets to orbit each other in a way where Planet A is tidally locked to the sun while Planet B is in geostationary orbit on the dark side of Planet A, thus putting Planet B in a constant total solar eclipse? by FenrirButAGoodBoy

No, not possible. Orbital speed is a function of distance between the two bodies, with closer orbits having faster speeds. This compounds with closer orbits also being shorter paths. The lit planet would be going around its star faster than the eclipsed planet, which would then un-eclipse it.
