The nature of cosmic dark matter, the exotic matter that makes up about 5/6 of all matter in the universe, ranks as one of the two biggest unsolved components1 of the biblically predicted big bang creation model.2 (The other big unsolved component is the nature of dark energy.3) The exotic property of cosmic dark matter is that, unlike ordinary matter (matter comprised of protons, neutrons, and electrons), it does not interact or very weakly interacts with light. Now, a recent paper published in Nature by two Harvard University astrophysicists4 brings us one step closer to comprehending the nature of cosmic dark matter and thereby giving us yet more reasons to believe in the biblical description of the origin, history, and nature of the universe.
