Phys. Rev. D 26, 947–949 (1982)Comment on a universal upper bound on the entropy-to-energy ratio for bounded systemsReceived 17 June 1981; published in the issue dated 15 August 1982 Some difficulties are noted with Bekenstein's arguments that a system with energy E and effective radius R has an entropy bound S≤SB≡2πER/ℏc. The inequality appears to be valid only for large SB. For that regime an upper bound which is generally stronger is proposed. © 1982 The American Physical Society URL:
