What Gravitational Waves Reveal About the Universe, with Michelle Thaller

Could spacetime curve in the opposite direction and produce a repulsive field instead of gravity? Neil deGrasse Tyson and comic co-host Chuck Nice tackle fan questions about photons, heat death, gravitational waves, neutron stars and more with astrophysicist Michelle Thaller. The episode opens with an urgent conversation about NASA funding cuts and the exodus of top scientists and engineers leaving for overseas programs.
