In his theory of relativity, Einstein claims that the black holes are so powerful so they can bend space and time, and they've condensed so much matter and energy into a single point that they could suck in forever anything nearby, including light. The problem with this idea it comes against the quantum principal which states that information cannot be lost.

Complex research made by physicians from Pennsylvania State University showed that such a point in space, where the time frontier ends can't exist, and therefore the information can't be permanently trapped in the black hole.
This implies that black holes will eventually evaporate and matter and information which was prior trapped inside the black hole's core will have the chance to come out.

If the new research is correct, then Einstein theory is not a perfect model, is just an approximation and leaves today's scientist to discover new theories beyond Einstein's physics.
