Theories of Everything with Curt Jaimungal · Ginestra Bianconi: The Physicist Who (Unexpectedly) Derived Gravity From Entropy · 13 Jul 2026 podcast

And so when you integrate something that is not homogeneous, you can get a dimensionality reduction.

That's the beauty of gravity from entropy.

And so for the moment, I don't feel the need to use a holographic screen.

And I think that, you know, there are many important insights coming from the area law, but if we are looking for a fundamental theory, we need to go beyond the area law.

So gravity from entropy...

assume that the geometry exists, and so it builds on Einstein's insight that gravity is a theory of geometry, but it provides new understanding of the interplane between matter, field, and geometry, but it doesn't want to explain where geometry comes from.

This is not the goal of gravity from entropy.

So as long as Einstein's theory might not be considered emergent gravity, but in some sense it is because, you know, Newtonian forces come from geometry, also gravity from entropy is at the same level, right?

So it assumes that the metric exists.

and capture the information content of this metric.

And of course, you know, Newtonian gravity comes from the geometry, exactly as in Einstein gravity.

Of course, a problem could be, you know, where geometry comes from, from the beginning, but this is not tackle in gravity from entropy.

What is emergent is instead this dark energy term.

That is dynamical and is new because it emerged from the theory and is driven by this G field.

Yeah, so of course there are the cosmological implications and the relation with prediction and, you know, possible experimental validation of the theory.

Then there are aspects related to the second quantization.

And then there are aspects related to entanglement.

So how this gravity from entropy action is related to entanglement and hierarchy entropy.

And then, of course, maybe if one wants to go also going in the discrete.

But what, you know, keeps me awake at night is the second quantization of this theory.
