how it's stored in the first place.

How a black hole could store information on a holographic plate, I think we do understand in great mathematical detail and also intuitively, and it's very much like an ordinary holographic

where you have a holographic plate and it contains all the information.

You shine a light through it and you get an image which looks three-dimensional.

Why should there be?

That is the great thing about being a theoretical physicist is

anybody can very quickly stump you with going to the next level of wise.

Yeah, you could just keep asking and it won't take you very long to...

So the trick in being a theoretical physics is finding the questions that you can answer.

So the questions that we think we might be able to answer now, and we've partially answered, is that there is a holographic explanation for certain kinds of things in string theory.

We've answered that.

Now we'd like to take what we've learned, and that's what I've mostly been doing for the last 15, 20 years.

I haven't really been working so much on string theory proper.

I've been sort of taking the lessons that we learned in string theory and trying to apply them to the real world

using only, assuming only what we know for sure about the real world.

Yes.

Okay, so first of all, the hair on black holes,

is a word that was coined by the greatest phrase master in the history of physics, John Wheeler, invented the word black hole.

And he also said that, he made the statement that black holes have no hair.

That is, every black hole in the universe
