Learn more about both, plus topics such as quantum theory, the Hubble Space Telescope, and the science (and fiction) of “Game of Thrones” in Symmetry writer Mike Perricone’s annual list of new popular physics books.

    Will we ever find dark matter in the universe?

      From Time, Dec. 6, 2019: Fermilab scientist Dan Hooper summarizes the current state of the search for dark matter.
