Quantifying Negative Energy from Entropy

  1. Dec 14, 2008 #1
    Entropy has an associated energy quantity that has negative pressure (cosmologically... spacetime).

    How does one calculate the quantity of this (negative?) energy from the entropy?

    Given that an event horizon has maximal entropy, would this produce significant repulsion?

    Anyway, I'd like to know how to calculate the quantity of this energy from the quantity of entropy.

    Thanks

    I do believe there is no such thing as negative energy...

    Despite your cross-post, I don't think this is quantum related. I understand this to be an area of recent mainstream research but not of accepted fact. You'll find details on the arXiv.
