Google failed me once more, and Askscience didnt approve it, so I come to you for answers.

As far as I know, once something crosses a black holes event horizon, it can not emerge again unless it becomes Hawkin Radiation (still unsure what that is as well, but thats another topic). In that regard, it doesnt matter what enters the black hole, physical matter or light, nothing gets out.

But many of the larger black holes emit quasars (I think thats the term), and from what I can tell these do have their origin in the black hole, so there is light (and possibly matter in the form of plasma?) being emitted from inside the black holes.

My question now is: How is it possible that this matter moves out of the black hole, if (as far as I know) nothing can get out? Of course there will be some part of the physics behind black holes that I am missing or misunderstand, Im just curious what that part is.

Inspired by the video "The deadliest events in fiction explained" by KateriLore on Youtube. I just watched it, and while extensive I immideatly could think of a couple more that were not mentioned. This led to the thought that man, there are a lot of these in books, games and movies, and so I thought it would be fun gather them in a list of bad events and mass death.

The video lists:

The Snap from Marvel (movies)

The Great Purification from Halo (video game)

The Reaper Harvests from Mass Effect (video game)

The Yuuzhan Vong War and the Destruction of Alderaan from Star Wars (movies/books)

The War in Heaven, the Noctis Aeterna and the Horus Heresy from Warhammer 40k (books)

Muad’dib’s Jihad from Dune (books)

Second Cylon War from Battlestar Galactica (series)

The One Year War from Gundam (series)

The War of 1996 from Independence Day (movie)

Judgment Day from Terminator (movies)

The Second Impact from Neon Genesis Evangelion (manga/series)

The Rumbling from Attack on Titan (manga/series)

During and after the video, I thought of a few more:

The War of Wrath from Tolkies Silmarillion (book)

The Infinitie War from Supreme Commander (video game)

The machine war from Matrix (movies)

The Fall from Eclipse Phase (TTRPG)

These just the ones that come to me without much thought, I am sure we can collect some more.

Google could not give me a good answer (or any at all, sadly), so I hope this fits here.

I was reading about the standing, professional mercenaries from around the 13th to 15th century, and while going through the different companies, battles and the like, a question came to my mind: Was the choice to be a mercenary really worth it? Or, more percise, did the common mercenary live long enough to enjoy their payment, or did most of them die in their first battles and never make it to "retirement" from the soldiers life?

From my (not very knowledgable) perspectice, fighting in these battles and wars must have been dangerous for the common mercenary, but they were also, if I understand it correctly, better trained and equipped than other (levied) forces at the time, which would up their chances of survival.

What interests me the most is if we have any idea to the casualty rates in these armies and companies, and as to how long their service period for their soldiers was.
