7:53Now PlayingWhat does it take to truly thrive on Mars? Neil deGrasse Tyson and Terry Crews tackle grab bag questions about Mars colonization and magnetic fields.
They explore whether we could develop technology to generate an artificial magnetic field to shield future Martians from deadly radiation. Would living underground defeat the dream of life on the Red Planet?
The conversation also dives into Earth’s shifting magnetic poles—what happens when the field weakens, how often it flips, and why you don’t need to panic about your compass spinning out anytime soon.
