from wikipedia: ************** https://en.wikipedia.org/wiki/Cosmological_constant_problem
In cosmology, the cosmological constant problem or vacuum catastrophe is the disagreement between the observed values of vacuum energy density (the small value of the cosmological constant) and theoretical large value of zero-point energy suggested by quantum field theory. Depending on the Planck energy cutoff and other factors, the discrepancy is as high as 120 orders of magnitude,[1] a state of affairs described by physicists as "the largest discrepancy between theory and experiment in all of science"[1] and "the worst theoretical prediction in the history of physics. ************** Further down the page it says newer calculations have reduced the discrepancy to only 10^60. I guess it doesn't matter. Physics must be fine since the Nobel committee is still handing out awards. Harry
