re: Black Hole Observations vs Computer Models.
Computer models have helped scientists evaluate new systems/black holes. They do not, however give answers to something that is new and different.
Computer models have been programmed with gathered data from specific sources. If a new source arives, albeit in the same realm, with different characteristics, a human eye, brain will have to determine the differences and ADD, the new findings onto the computer modules for future reference.
The truth is in there... humans first, computers second. :}
