thanks

Great explaintions sir!

As an aspiring astrophysicist, you should view information conservation as a non-negotiable requirement because it is essential to the unitarity of the S-matrix, which ensures that total probabilities always sum to one within quantum mechanics. If information were truly lost, the foundational mathematical framework of the universe would lose its predictive power, as past states would no longer uniquely determine future ones. Professor Mathur’s “litmus test” is therefore considered the correct standard for a consistent theory of quantum gravity, it forces us to move beyond the semiclassical “empty” black hole model and instead account for complex, string theoretic states like “fuzzballs” that allow information to be encoded in radiation, preserving the fundamental reversibility of physical law.

thank you sir for the course
