Infalling observers are reaching the event horizon of a black hole in finite time. In contrast, from the point of view of a far-away observer, an infinite time has passed at this moment, and the same is true from the point of view of external observers in general.
Is there a way to join these two points of view? Does there exist a concept of how the universe is supposed to look like at this moment from the point of view of outside observers, in particular with respect to particle worldlines and events, is there a concept for the existence of worldlines and events in infinity, or is the universe supposed to be not defined at the moment when the infalling observer is reaching the event horizon?
Edit:
I would like to keep this question open because it is not identic with the "duplicata" "Does someone falling into a black hole see the end of the universe?".
The cited question is referring to interactions with the infalling observer (in particular light rays reaching her). In contrast, my question is asking for the status of the whole surrounding universe at the moment when the observer is reaching the event horizon. This is no problem for light rays which are reaching the infalling observer at the EH because they are emitted at some finite instant before being absorbed by her.)
So, my question has not been answered by the cited question, it is different.
