Now that we've seen that you don't need that assumption, the whole thing has no basis.
I mean, if it's true, we think it's true, we have an example of a theory which doesn't require that assumption and which is what we call UV-complete.
It has a full continuum formulation.
This is a self-contained complete theory, like QCD, we believe is such a theory.
Yet it doesn't live in a Hilbert space.
It lives in a space with more like Minkowski space with positive norm states and negative norm states and null states.
Just a tiny generalization of the orthodox principles means you don't need strings, you don't need extra dimensions to describe gravity.
That's quite shocking.
Of course, it begs the question, what are the other assumptions that people were making, which led them to conclude there's a multiverse?
You make one false move,
in theoretical physics, and you're totally wrong, okay?
So that's the danger we all have to worry about.
And I think people are not sufficiently worried about that.
We should be examining very, very closely each one of our assumptions to say, is it really necessary, or is it just that we're traditionally used to making that assumption?
Yeah, exactly, exactly.
Exactly.
Negative energy.
No.
I'll tell a little bit more about that horn, because there's this Ostrogradsky instability.
Now, the fascinating thing about gravity is it has this character, that gravitating system, gravity has negative energy, right?
