The 66-Million-Year-Old Cold Case

For decades, the downfall of the dinosaurs has been neatly filed under a single, cataclysmic culprit: a massive asteroid that slammed into Earth, triggering a mass extinction. But in Dark Matter and the Dinosaurs , renowned Harvard physicist Lisa Randall proposes a far stranger, more cosmic twist. What if that killer asteroid wasn't a random stroke of bad luck, but a predictable consequence of our solar system’s journey through the Milky Way—and what if the invisible hand guiding that journey is the mysterious substance we call dark matter?

Randall’s groundbreaking theory suggests that dark matter might not be a diffuse, featureless halo. Instead, it could concentrate into a thin, dense —a shadow galaxy aligned with our own. As our solar system bobs up and down through the Milky Way’s galactic plane, it periodically passes through this disk of dark matter. The gravitational perturbations, Randall argues, would be enough to jostle comets from the distant Oort Cloud, sending a deadly volley of them hurtling toward Earth. One of those, 66 million years ago, ended the age of reptiles. The 66-Million-Year-Old Cold Case For decades, the downfall
