The book's central theme is how subatomic, invisible particles can influence the biological history of our planet. Key Content of the Book —could have collapsed into a dense disk within
In this brilliantly accessible EPUB edition, Randall takes you on a breathtaking ride from the smallest subatomic particles to the grandest structures of the galaxy. She weaves together two seemingly unrelated mysteries: the nature of the invisible dark matter that makes up 85% of the universe’s mass, and the periodic comet showers that have pummeled Earth every 35 million years or so.
Randall supports this by pointing to crater records on Earth, which suggest a weak periodicity of roughly 35 million years. While not conclusive, the data aligns eerily well with the solar system’s 32-million-year vertical oscillation through the galactic plane. Stick to library loans or legitimate stores

If a dark disk exists in that plane, the Solar System would pass through it. The gravitational influence of this concentrated dark matter would be significant enough to disturb the Oort Cloud—a vast shell of icy debris and comets surrounding the outer reaches of our solar system.
Crossing this dense dark matter disk creates an "extra tidal force" that gravitationally destabilizes icy bodies in the Oort Cloud , a distant region of our solar system. Earth Impacts:
