Information Content of Gravitational Radiation and the Vacuum

Understand

Known entropy bounds, and the Generalized Second Law, were recently shown to imply bounds on the information arriving at future null infinity.

• We complete this derivation by including the contribution from gravitons.
• We test the bounds in classical settings with gravity and no matter.
• In Minkowski space, the bounds vanish on any subregion of the future boundary, independently of coordinate choices.
