Brian Cox stories - he played keyboard before Thin Lizzie guy recruited him

And there's another description, by the way, of this world that we live in now, this is really cutting-edge stuff, there's an equivalent description of our experience in this theatre contained on a boundary surrounding the theatre, and it's called the holographic principle. So there are two ways, it seems, of describing our reality one is as a reality with gravity in it, and the three dimensions of space and time, and the other one is a pure quantum theory, on a boundary, and that's called the holographic principle because that's what a hologram is. So there's a sense in which we're all holograms, really strange. But it's interesting, isn't it, because it's the study of black holes, and then just doing some mathematics, which Stephen pioneered in the '70s, which has ultimately led to something deeply hidden.
Interviewer: "But they're still theories, aren't they, they're not proved?"

What's really interesting is that the very strange and arcane mathematics that are being used, it turns out it's the same mathematics that we use when we're programming quantum computers, and quantum computers are real things that we have in laboratories. It's the best argument, by the way, for funding blue skies research that you'll ever get. You know when politicians always say, why should we fund this stuff, what are you people doing thinking about black holes, you should think about something else that matters; actually, it turns out that there's been an intimate crossover between solving problems of error correction in the memory of quantum computers, which is fundamentally important, and the study of black holes.

That doesn't mean we live in a simulation, by the way, I think that would be pushing it a bit far, but it's very, very interesting.

I'll say this, I didn't say it in that clip, but every time you make a programme about Newton, or gravity, and the history of that science, we always talk about Galileo, and Galileo said that the book of nature is written in the language of mathematics, it's a very famous quote. In the 20th century, I think, well all the way through from Galileo, actually, through the 20th century, if you'd have said to people, what is God, you would have God is a mathematician, whatever God is, God is a mathematician.

And now, in the 21st century, partly motivated by the study of black holes, people are saying God looks more like a programmer, because it's information that seems to lie at the base of reality. So we're beginning to wander into the realm of information theory, which the great John Wheeler, one of my great heroes, actually, Kip Thorne, who worked on "Interstellar,"...
