I'll add that what happens at or near the event horizon isn't certain either. Since we haven't been able to really observationally (indirect or direct) probe that close, there is active interest in the details near the event horizon.
The Black Hole at the Core of the Milky Way, Sagittarius A*, is about to consume a giant gas cloud, later this year (or rather later in a year 25,000 years ago)

During the part of our history in which we could have 'seen' such things, SgtA* has been quiet and well-behaved, for a galactic centre Mega BH, so this will be an event of great interest, precisely for those reasons. For the first time we will see, close-up, an enormous mass hit a black hole, and if theory is are correct form an accretion disc, galactic jets and some actually enter the event horizon. Now THAT will be an APOD to remember!
