Further Explanation of the Cosmological Constant Problem by Discrete   Space-time through Modified Holographic Principle
  The author proposed in his previous papers in 2001 that the problem of the cosmological constant could be resolved and its calculated value agrees excellently with the observations by assuming that the space-time itself, as the phase of Higgs condensate, is discrete in nature. Further to such idea, a different approach involving the concept of vacuum entropy that is constrained by the modified Holographic Principle is being used in the calculation of the cosmological constant value at three different phase transition times in the early universe. It is interesting and quite unexpected that it arrives at the same conclusion as the previous approach. It therefore reveals that something fundamental is present in the theory. The problem on the preservation of Lorentz invariance in discrete space-time is also discussed.
