The Elephant in the Universe

Our Hundred-Year Search for Dark Matter

Govert Schilling 2022 Bvtn Lib 523.1126 SCH

A well written, mind changing book, decent reference material. I might purchase a used copy, even though local libraries have copies. Washington county libraries also have Deep Space (2014), Ripples in Spacetime (2017) and Constellations (2019), and Multnomah County has Galaxies (2019).

History of the idea of dark matter. I haven't yet finished reading the book.

The 900 pound gorilla in the room (so far) is that there is a lot more invisible gravitational mass at the galactic scale than does not interact electromagnetically.
