Theories of Everything with Curt Jaimungal · Neil Turok: A Route to Quantum Gravity (Without Strings) · 22 Jun 2026 podcast

This is a very fundamental problem.

So we were studying these four derivative fields on a fixed background.

So Klein and Hell took the same model of these four derivative fields and said, okay, let's study that as if that describes the dynamics of gravity.

That's not what we were doing.

And then they discovered that this is not a good theory of gravity.

Well, you know, so what?

It's not what it was invented to do.

So we have to add other terms which describe gravity, and then we have to combine the whole thing.

So yeah, their analysis seemed off the point.

And then secondly... So their analysis was correct, but it wasn't what you were saying.

I'm not sure it was correct.

The paper is not clearly enough written to tell.

Okay, but either way, it's not what you were saying.

Totally irrelevant to what we were saying.

The other thing is they repeat the folklore that negative norm states are not admissible.

And therefore, they just completely missed the point, which is in our latest work, that to describe four derivative theories, you have to be willing to include negative norm states.

If you just rule them out from step one, I agree with them, you can't do...

The normal procedures of quantum mechanics don't work, or quantum field theory don't work.

But that's why you have to go beyond them.

So, yeah, I mean, there are lots of other issues with their paper.
