  • Title: Dark Matter ‘Hairs’ Around Earth
"This illustration shows Earth surrounded by filaments of dark matter called 'hairs'...A hair is created when a stream of dark matter particles goes through the planet. According to simulations, the hair is densest at a point called the "root." When particles of a dark matter stream pass through the core of Earth, they form a hair whose root has a particle density about a billion times greater than average."
