Proof of Classical Versions of the Bousso Entropy Bound and of the Generalized Second Law

  title={Proof of Classical Versions of the Bousso Entropy Bound and of the Generalized Second Law},
  author={{\'E}anna {\'E}. Flanagan and Donald M. Marolf and Robert M. Wald}
Bousso has conjectured that in any spacetime satisfying Einstein’s equation and satisfying the dominant energy condition, the “entropy flux” S through any null hypersurface L generated by geodesics with non-positive expansion starting from some spacelike 2 surface of area A must satisfy S ≤ A/4Gh̄. This conjecture reformulates earlier conjectured entropy bounds of Bekenstein and also of Fischler and Susskind, and can be interpreted as a statement of the socalled holographic principle. We show… CONTINUE READING
