So we don't know how it emerges, it's a very strange thing, but it emerges from this collection of atoms in a particular pattern. Well, we think now, from the study of black holes, that space and time emerge from something else, which is kind of... One way to describe it is just a quantum theory. So in quantum computing terms, it would be just qubits

So a network of qubits entangled together, just like a quantum computer. Out of that, we suspect that space and time might emerge. So surely we have to understand that process, and we don't really fully understand that, but we have glimpses of it in much more detail to start talking about the origin of time. Because in order to talk about the origin of time, you have to know what it is.

And we don't actually know what it is, which is, you know, and that's kind of when you say that it sounds bizarre, doesn't it? Well, how can you not know what time is? I think Einstein once said that it is the thing that you measure on a watch. But he said that as kind of almost a joke, because you assume in Einstein's theory, there's a thing that the watch measures.

But what actually it is at the deepest level is a good question. But it's interesting the study of black holes is forcing us towards these theories. It's not that we had the theories face and time emerging from something and decided we could check it by thinking about black holes. It's come the other way around, really. So it's interesting. But that almost makes...

the universe look in some ways like a giant quantum computer, which is not to say that we live in a simulation, before you ask. But it just looks like there's a description of the universe that looks like a quantum computer type description. That doesn't have the concept of space or time in it.

It is. It's interesting that you're right. And that's a good way of phrasing it. It mimics or looks like a network of qubits. So it looks like some kind of quantum computing description is available to us, to the universe. But I don't think you can infer much from that. I mean, it just passes the question further back.

As I said, we have never understood what it means for the universe to have a beginning. So we don't really know that. And so this is the same. I think it's just the same question. It's like, well, you ask, well... If it really is a network of qubits, it could have been there forever, that network of qubits. Actually, in quantum theory, it's more natural for it to be just eternal.
