Einstein's "biggest blunder" beats dark energy in explaining expansion of the UniverseSubmitted by Bob-45 on Thu, 01/17/2013 - 16:21

It is dangerous to bet against Einstein. Cosmological research shows that the rate at which the Universe expands is increasing, rather than decreasing as was previously thought. The concept of "dark energy" with a negative pressure was introduced to describe this acceleration. Now measurements of the proton to electron mass ratio (PEMR) over the past seven billion years strongly suggest that the models of dark energy are far more contrived in explaining accelerating expansion than is Einstein's self-proclaimed "biggest blunder" – the cosmological constant.
The Standard Models of particle physics and of cosmology work surprisingly well. Some physicists would say distressingly well, as we are usually led toward new physics by the breaking down of our current understanding. Right now, however, there seem to be few experimental results that even hint there is new physics to be discovered.
