“Any fool can criticize, condemn and complain – and most fools do.” -Benjamin Franklin
The history of science is rife with stories of cases where a person or team, usually with a lot of clout, reached a conclusion that seemed incontrovertible. When that occurs, we often find that subsequent measurements agree with that conclusion, even if that conclusion later turns out to be wrong.
Recommended speed of light values over time. Adapted from Henrion & Fischhoff (1986).
This was the case for measurements of the speed of light and for the various masses of fundamental and composite particles during most of the 20th century. Could that also be the case for cosmology, and in particular for cosmological parameters like dark matter, dark energy and the expansion rate of the Universe?

Perhaps, but only to a degree, argues Brian Koberlein. Go read the full story.
