Please join my mailing list here https://briankeating.com/list to
win a meteorite Remastered from our interview in 2022.  There
are few concepts in physics as frequently discussed but as poorly
understood as dark matter. After all, we don’t even know what it’s
made of!  However, there are many potential candidates, and I
had the pleasure of explaining them in my interview with Arvin Ash.
We also talked about the fascinating possibility of detecting
gravitational waves from the polarization of the CMB and why it is
very likely that there is, in fact, no life outside of Earth.
