Dark Energy and String Theory

  1. Apr 17, 2014 #1
    If dark energy is caused by quantum fluctuations, where does this energy come from? Also according to string theory mass is determined by the sum of a string's positive, vibrational energy and its negative energy from quantum fluctuations. Could it be possible to create a particle with negative mass by creating a string with more energy from quantum fluctuations, than vibrational energy?

    If it is caused by quantum fluctuations ... then it doesn't come from anywhere, and simply comes and goes.

    Your further suppositions don't seem to be well founded.
