    I’m aware of the Penrose diagram and also watch PBS SpaceTime :)

    But I was referring more to the frame of reference of our universe vs that of being inside a blackhole (assuming you could magically avoid being ripped apart by gravity). To an observer inside a blackhole, “time” on the outside would blink by almost instantly. I wasn’t talking about moving through an infinite universe or near/into a black hole. Just stationary, floating just beyond the event horizon, looking out. Hence the asterisk on basically*.

    I was leading them to what MotoAsh posted. But they beat me to it while I was typing.

    Edit: He even references what I’m talking about at 0:44 in the SpaceTime video. But from the frame of reference of an outside observer.

    Yes, but if you’re beyond the event horizon of a black hole time becomes basically* irrelevant. You could literally turn around, look back out towards the rest of he universe, and watch all of time play out in the blink of an eye.

    You know that scene in Interstellar where they land on the planet for 5 minutes, but 20 years passes for everyone else due to the planet’s mass? It’s the same thing, but a billion-billion-billion times more severe.








  • Fun Fact: I once worked with a team that were mapping Iran’s internet infrastructure… for reasons. One of the ways we were able to zero in on the more important systems was because we kept finding these weird Cisco routers that had Telnet exposed to the open internet. All of which just so happened to share neighboring IPs (or close enough) with some pretty serious government systems. Fun times.

    I’m not a CISCO tech, so I don’t know the specifics beyond that. But I do remember that the Telnet connection would permanently ban any IP that failed even a single password attempt. So they had that going for them, I guess lol
