Understand

It is possible to provide a thermodynamic interpretation for the field equations in any diffeomorphism invariant theory of gravity.

This insight, in turn, leads us to the possibility of deriving the gravitational field equations from another variational principle without using the metric as a dynamical variable.
I review this approach and discuss its implications.
