A reader of my article Big bang fudge factors wrote the following comments: Dark matter has been detected: neutrinos fit the definition of Weakly Interacting Massive Particles, as they have such small probabilities of interacting with atomic matter that it takes several moles of neutrinos to achieve the same probability of a single interaction as […]

Unseen dark matter has been invoked several times to solve problems in astrophysics and cosmology. Historically the most significant problem has been the rotation curves of galaxies, particularly spiral galaxies. Using the Doppler Effect the speeds of the stars and gases in the disk regions of spiral galaxies can be measured. See Fig. 1. By […]
On August 19, 2016, the “SUSY Bet” event took place in Copenhagen at the conference on Current Themes in High Energy Physics and Cosmology at the Niels Bohr International Academy. An adjudication of the wager on supersymmetry (SUSY) first made in 2000 was given. The detail of wager is explained in the image below. Supersymmetry The bet involved two […]
An online news report1 from phys.org, titled “Scientists looking for invisible dark matter can’t find any,” reported the following: Scientists have come up empty-handed in their latest effort to find elusive dark matter, the plentiful stuff that helps galaxies like ours form. For three years, scientists have been looking for dark matter—which though invisible, makes up […]
