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. 

Tune in!

Key Takeaways:
