Abstract: We provide some up-to-date discussions related to cosmological event horizon and entropy of our universe, then introduce an intriguing idea that there may be a universal finite upper bound for entropy accessible to an observer in consistent theories of quantum gravity. We argue that the BMN (Berenstein-Maldacena-Nastase) strings provide a test of the idea and a possible estimate of the cosmological constant.
