#2506 - Michelle Thaller
"We run our physics and we say, if you have this much volume and this much mass, what should that interior be like? None of our current models of how matter works gives us the right observations, gives us the right size."
Dr. Michelle Thaller, former NASA communications director, disclosed that despite measuring neutron stars with teaspoon-sized samples containing the mass of Mount Everest, current physics models cannot describe their interior state. NASA's NICER mission observes these objects but the density at their core defeats all existing equations, indicating a new state of matter we cannot yet characterize.

About this episode

Joe Rogan sits down with Dr. Michelle Thaller, former NASA communications director and astrophysicist, for a sweeping three-hour conversation exploring the most profound mysteries in science, consciousness, and the nature of reality. Thaller opens by explaining the incomprehensible scale of the Milky Way galaxy—if the sun were the size of a dot of an 'i' on a page, the galaxy would be larger than Earth itself—before diving into cutting-edge NASA discoveries that challenge fundamental physics. She reveals that neutron star interiors contain matter so dense that current physics models completely fail to describe them, representing an entirely new state of matter beyond scientific understanding. The conversation turns to the James Webb Space Telescope's mysterious 'little red dots,' which Thaller suggests may be the first black hole seeds formed immediately after the Big Bang, solving the longstanding puzzle of how supermassive black holes grew so large so quickly. She details the astonishing precision of the Event Horizon Telescope's 2019 black hole image, explaining that eight observatories had to catch the same photon traveling at light speed to within one-millionth of a meter. Perhaps most striking is her disclosure that NASA's OSIRIS-REx mission found all the nucleobases of human DNA and RNA on asteroid Bennu, providing compelling evidence that life's building blocks literally rain down from space. The discussion expands into quantum entanglement, the nature of time, and whether reality itself is fundamentally different from human perception. Thaller candidly discusses her conversations with people claiming time travel and alien contact, her interest in psychedelics for grief therapy after her husband's death, and the limits of scientific knowledge. She argues that AI may represent the next evolutionary step for humanity rather than an existential threat, comparing the transition to the leap from Australopithecus to modern humans. Throughout, Thaller balances scientific rigor with profound humility, repeatedly emphasizing what remains unknown while celebrating humanity's audacious achievements in probing the cosmos.
