Science works... spending on science is important because scientific inquiry in one topic often pays dividends in other areas of inquiry. Recently, a facility designed as a dark matter detector has observed a two-neutrino double electron capture, a radioactive decay process by which two protons in an atomic nucleus absorb two electrons and release two neutrinos. The next project will be to observe is a neutrinoless electron capture is possible, which would imply that neutrinos are their own antiparticles. The search is still on for dark matter, which is thought to compose 27% of the universe's makeup, but which only interacts with baryonic matter through the force of gravity.
My go-to authority on the... uhhhhh... matter of dark matter is Dr Priyamvada Natarajan of Yale University, who delivered two Secret Science Club lectures on dark matter. Here's a TED talk by the good doctor on dark matter:
For a more in-depth exploration of the matter, the Fermilab has an hour and a half lecture by Dr Natarajan on dark matter and black holes. While the subject matter may be hard to wrap one's head around, I think that Dr Natarajan's almost musical accent makes the lecture fun to listen to even if you are physics averse.
The Secret Science Club also featured a lecture on neutrinos by Dr Ray Jayawardhana of the University of Toronto. I am particularly enchanted with the idea of tying together our knowledge of the infinitesimally small universe within each atom with our knowledge of the mind-bogglingly vast multiverse. Science, I repeat, works.
