TL;DR

Links for scientifically accepted theories on black holes

Can someone post links to the popularly accepted theories on black holes? Just about all of the information I come across is presented as scientific fact, regardless of how far-fetched some of these ideas may seem, or contradict each other

Just google "black holes"

Any introductory GR textbook will cover black holes, and none will contradict one another in any significant way.
