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 a single neutron or photon. Though individually nearly massless and invisible to matter, the sheer number of neutrinos surrounding us makes it possible to detect them, and makes their combined energy a significant component of the mass of the Universe.
Likewise, Massive Compact Halo Objects are quite ordinary matter. They are planetary and sub-planetary bodies, producing little or no light, and so hard to detect. To these, we add black holes, neutron stars, and brown dwarfs, which also emit little or no light, despite their mass.
Neither should the existence of dark energy be any surprise to Christians. After all, the Bible say, “The heavens are stretched out like a curtain.” Dark energy is the energy of the vacuum state, less than 1 microjoule per cubic meter, distributed uniformly. Only because of the vastness of space are we able to observe its effects. Even so, were this tremendous amount of energy somehow liberated, “the elements shall be consumed by fire.” The decay of the vacuum state, unleashing the tremendous amount of energy stored in it, could very well be the means by which the Lord transforms the Universe at the end of the age.

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.
The bet involved two aspects of supersymmetry theory.1
- That after 10 years (from 2000) the Large Hadron Collider (LHC) would have collected enough experimental data to confirm or deny the existence of the supersymmetric particles that the theoretical physicists were thinking about at that time.
- That supersymmetric particles with sufficiently low masses would be discovered like “sitting ducks” (as Gerard ‘t Hooft put it).
At the event, the Yes side of the bet, who believed the particles would be detected, conceded the loss of the bet to the No side. The bet was meant to be decided on June 16th 2016 if no SUSY particle was detected after effectively 10 years of operation of the LHC. The adjudication of the bet was extended by the ‘No’ side by an addition of 6 years due delays in getting the LHC online, part of which was a delay due to an explosion, which caused a delay of 2 years.
On the larger question of the significance of the negative LHC results, a recorded video statement by Nobel Laureate Gerard ‘t Hooft (who had bet against SUSY) can be viewed above, and a statement by Stephen Hawking (not in on the bet, but in the audience) claimed that if arguments for SUSY were correct, the LHC should have seen something, so they think nature has spoken and there’s something wrong with the idea.
