Information in black holes

    Occasionally on the radio I hear a cosmologist say something about how information has to be preserved, even in black holes. What are they talking about? Is this something to do with entropy? Likewise I watched someone on YouTube say he did not think we were living in a simulation, partly because if he himself were to design a simulation of the universe, he'd throw away the bits. I assume he talking about information again, and that by bits he's talking about unavailable energy.

    I think in both cases they are talking about, what we currently think are, the fundamental building blocks of the physical world. I guess it's like the energy theory of it can't be destroyed, only turned into something else.

    As far as the simulation thing goes. I just see that as the latest version of the creation myth. Just like any religious belief it's not easy to prove or disprove.

    If we are in a simulation, wouldn't you expect those running the simulation to have taken those little things into account?
