Could dark matter have killed the dinosaurs? Harvard astrophysicist Lisa Randall's mind-bending theory connects cosmic physics to Earth's greatest extinction, earning praise from The Wall Street Journal as "storytelling of the highest order" while sparking fierce scientific debate across disciplines.

Sixty-six million years ago, something the size of Manhattan slammed into Earth at 20 kilometers per second-700 times faster than highway traffic. The impact released energy equivalent to a billion Hiroshima bombs. Within hours, tsunamis ravaged coastlines, wildfires consumed continents, and superheated debris rained from the sky, cooking the planet's surface. The dinosaurs, rulers of Earth for 180 million years, were gone. But here's the twist: what if their extinction wasn't random cosmic bad luck? What if invisible matter lurking in our galaxy's shadows orchestrated this catastrophe? This is the audacious premise connecting particle physics, paleontology, and cosmology in a story that spans from subatomic particles to galactic structures, from the universe's first moments to the asteroid that changed everything. Right now, billions of dark matter particles are streaming through your body. You don't feel them because they pass through ordinary matter like ghosts through walls. This isn't science fiction-it's the strange reality of our universe. Dark matter makes up 85% of all matter, yet it's completely invisible because it doesn't interact with light or any electromagnetic force. Our senses evolved to detect electromagnetic interactions, so dark matter exists in a parallel reality we can never directly perceive. Think of it this way: we miss obvious things constantly. Your brain filters out the pressure of air on your skin, the blind spot in each eye, even the bacteria outnumbering your own cells in your body. Dark matter takes this invisibility to an extreme. It's not dark like a black hole that absorbs light-it's transparent, letting light pass through unchanged. The name is misleading; "transparent matter" would be more accurate. Without dark matter's gravitational pull, galaxies wouldn't have formed quickly enough for stars, planets, and life to emerge.
