Artikel in Deutsch : Das Ende der Zeit oder warum keine „schwarzen Löcher“ entstehen können
Singularity– infinite bend of the space time -, Black holes called, arise under certain boundary conditions
from the general theory of relativity.
In Wickipedia you can read a lot of interisting thinks about Black holes by yourself - here are only the point about
the Event horizont

“The defining feature of a black hole is the appearance of an event horizon—a boundary in spacetime through which matter and
light can only pass inward towards the mass of the black hole. Nothing, not even light, can escape from inside the event
horizon. The event horizon is referred to as such because if an event occurs within the boundary, information from that
event cannot reach an outside observer, making it impossible to determine if such an event occurred.[42]
As predicted by general relativity, the presence of a large mass deforms spacetime in such a way that the paths taken by
particles bend towards the mass.[citation needed] At the event horizon of a black hole, this deformation becomes so strong
that there are no paths that lead away from the black hole.
To a distant observer, clocks near a black hole appear to tick more slowly than those further away from the black hole.
[43] Due to this effect, known as gravitational time dilation, an object falling into a black hole appears to slow down as it
approaches the event horizon, taking an infinite time to reach it.[44] At the same time, all processes on this object slow
down causing emitted light to appear redder and dimmer, an effect known as gravitational redshift.[45]
Eventually, at a point just before it reaches the event horizon, the falling object becomes so dim that it can no longer be seen.”
The point of interesting is: “...taking an infinite time to reach it”.
What practically this means, the event horizon at no time is passed.
In the reverse is for the object with reach of the event horizon endlessly a lot of time in the remaining universe pastly (all time?). It reaches the event horizon at the temporal end of the universe.
If nothing can pass the event horizon, as long as the remaining universe exists, then there are black holes in this universe?
