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.
