I don't have the knowledge or smarts to give much detail about it but there's some rather interesting parts of this in Quantum Mechanics and Entropy. Along with that it's also one of the fun little areas of things that may or may not be breaking down with our current models around black-holes and our understanding of gravity. It's an active area of research because of this because it may point to a way to reconcile the incompatibilities between QM and Relativity to get a Grand Unified Theory. I believe Loop Quantum Gravity ends up with effects around this mass-energy-information/entropy equivalence idea as an emergent property of how it's trying to reconcile QM and Relativity.
