How long does it take a infalling observer to cross the event horizon of a black hole?

According to GR, time stops at the event horizon. It would take infinite time to cross the event horizon. Everything past the event horizon is speculative.

Einstein didn't think black holes existed (1916) and it took until 1971 with Cygnus X-1 for serious consideration, which was the smoking gun. 55 years of being considered probably a math fluke and then observational evidence.

Although discrete models may not exist, discreetness is expected because without there's likely unsolvable informational problems. This is why Beckenstein was so brilliant, he was among the first to understand physical systems must fit

>infinite “information” is not really a thing. That's the point. That's why a continuous universe is absurd from an informational perspective.

I can't help but see this as evil. Giving more control to corporations and less control to individuals.

I think this is solved by "authenticated atomic action", where users sign individual interactions instead of trusting login servers. In this case, each upvote, downvote, and comment must be cryptographically signed. Once user act
