The Evidence is Building that Dark Matter is Made of Axions

There’s some potentially big news on the hunt for dark matter. Astronomers may have a handle on what makes this mysterious cosmic stuff: strange particles called “axions.”

Rather than search directly for axions, however, a multinational team of researchers led by Keir Rogers from the University of Toronto looked for something else. They focused on the “clumpiness” of the Universe and found that cosmic matter is more evenly distributed than expected.

Direct searches for axioms have so far found nothing. The energy range of the classical axion is already eliminated, and what is left as possible is a small energy band of about the same mass as the neutrino.

As for cosmic matter being more evenly distributed than expected. That makes me smile, because I’ve previously heard on at least three separate occasions that cosmic matter is less evenly distributed than expected.
