Astrophysicist Michelle Thaller explains how we caught the same photon of light across Earth-sized telescopes, why black holes are brighter than galaxies, and what the OSIRIS-REx asteroid sample reveals about life's cosmic origins—challenging everything we think we know about space, time, and reality itself. We detected gravitational waves in 2015 by measuring space-time distortions smaller than an atom's nucleus, proving Einstein's prediction and opening a new way to observe the universe beyond light.
