Astrophysicist Jason Kristiano discusses primordial black holes, their formation, impact on the Universe, observational methods, and potential as dark matter solution. From quantum fluctuations in inflation to gravitational wave detection challenges, the conversation explores new perspectives on cosmology and fundamental forces.

Satellites run out of fuel and have to de-orbit and end their missions. But what if they had access to a practically infinite amount of fuel? What if they could scoop air from the atmosphere and use it as propellant?
