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.
My responses are below. Continue reading
