[Interview] Practically FREE Primordial Gravitational Waves Detector
Not every new space mission needs a separate launch and dedicated hardware. With this proposal, there's a huge potential for finding signals from primordial black holes by just using signals from a spacecraft flying to Uranus or Neptune. No additional hardware required.

Customer Reviews
I like this show, but …
… I have to assume FC is joking when he talks about alien civilizations building Dyson spheres, moving stars and planets and harvesting energy of entire galaxies.
Awesome insightful incredible
This podcast teaches the how’s and why’s about the amazing universe we live in.
Great Work
When listening I can tell not only how much he cares about what he does but manages to present it in a fun way for the people, I would highly suggest listening to universe today if you any to have your science questions answered or just love space
