New hypothesis suggests dark matter wiped out the dinosaurs

And, bear with us here because we know it sounds kind of far-fetched, but it actually makes a lot of sense. Publishing in the Monthly Notices of the Royal Astronomical Society, Michael Rampino, a geoscientist at New York University in the US, explains that mass extinctions occur roughly ever 26 million to 30 million years on Earth - around the same time our Solar System passes through the disc of the Milky Way. In the past, researchers have noticed this association, and suggested that perhaps clouds of dust and gas, and possibly even dark matter, in the Milky Way’s plane might be somehow shaking comets off their orbits and causing them to slam into Earth, triggering these mass extinctions.

According to his hypothesis, dark matter could trigger all kinds of problems on Earth. As Perkins explains in Science: Source: Science.

The relationship between money, power, and our wellbeing is formed by our association of self-worth with the possession, or paucity, of authority and currency.
