Acceleration of a universe with -ve Cosmological Constant

  1. Jun 9, 2012 #1
    I have read this new paper by Stephen Hawking and collegues.
    It is very interesting to see the use of wavefunctions to show the acceleration of a universe with lambda<0 which fits in the framework of string theory and quantum mechanics. This technique bridges quantum mechanics and general relativity to a satisfactory level.

    I wish to have your feedback on the paper.

    We already have a thread commenting on this paper:
    https://www.physicsforums.com/showthread.php?t=606988
    The thread is just a little ways down the menu from yours (about 16 or 17 items down) and it is called "Accelerated Expansion from Negative Lambda".

    "MTd2" started the thread in mid-May as soon as the paper appeared and Brian Powell immediately made an intelligent observation:
    Basically, I think, we are waiting to see what the professional string research community does with this: whether (after this shot of adrenaline) the apparently dead body on the operating table gets up and walks away :biggrin:
