Earth might be in a bit of a ~hairy~ situation, and it involves some ~spooky scary~ space stuff called dark matter: “an invisible, mysterious substance that makes up about 27 percent of all matter and energy in the universe,” according to NASA.
While dark matter might sound like a high school garage band (which, let’s be real, it probably is), it’s actually a big ol’ space mystery, since it’s never been directly detected by scientists. But a new study from Gary Prézeau of NASA’s Jet Propulsion Laboratory is giving us an inside look at this incredible enigma.
Prézeau used computer simulations to find out what happens when streams of dark matter go through planets, including Earth. “His analysis finds that when a dark matter stream goes through a planet, the stream particles focus into an ultra-dense filament, or ’hair,’ of dark matter. In fact, there should be many such hairs sprouting from Earth.” NASA reports.
