Red shift and zero point energy

  1. Oct 24, 2007 #1
    Is there a relationship between red shift of galxies and zero point energy?
    Has the zero point energy changed over time?

    If, as Fritz Zwicky thought, redshift arises from light's interaction with the space through which it propagates, yes. Einstein thought that light had to interact with space (as a transmissive medium, too). Today, we are MUCH smarter and have no truck with such crazy ideas. :rolleyes:

    There are a few modern theoreticians including Fotini Markopoulou-Kalamara, who think that light may interact with the the transmissive media (space) through which it propagates, and that since high-frequency EM must interact more frequently than low-frequency EM, that high-frequency EM must be delayed relative to the low-frequency EM. The MAGIC consortium has recently published about such a delay, though this observation has not been replicated.

    zero point energy changes?

    Thanks for the reply that is what I have read also about space no really bieng a compleat vacum there fore causeing a slight index of refraction. Any thoughts on zero point energy changing over time?
