Black holes run into the problem of infinity-- a black hole's mass is crushed to an infinetly dense point that's infinetly small in size. Physically, this doesn't make any sense, so researchers have searched for alternative frameworks to get a better understanding of black holes. One proposal is known as quantum loop gravity, which suggests that the fabric of space-time is curved very strongly near the center of the black hole. This would result in part of the black hole extending into the future, meaning that matter getting sucked into it would time travel forward. So far, this mind-expanding idea remains theoretical.
