In calculations that date back to the 1990s, researchers have suggested that long, fine streams of dark matter criss-cross the Universe. Prézeau estimates there could be a “root” where the Universe’s dark matter originates and he plans to find it next. Regular matter, which makes up everything else, can easily been seen; however, regular matter only makes up about 5 percent of the universe. A new study simulates streams of dark matter rooted in the planet’s core that would create filaments, or “hair”, of dark matter around the planet.

According to Prézeau’s latest research, when a dark matter stream passes through a planet, the stream particles concentrate into an ultra-dense filament, or “hair”, of dark matter.
If dark matter were visible, the Earth would be in need of a haircut.
Based on simulations, researchers determined that dark matter orbits around galaxies like the Milky Way in particle streams, according to NASA. Those hairs emerge out the other side of the planet, while the roots of these hairs are more than a billion times more dense than the original streams.
The root of one such hair should be around 1 million kilometers away from the surface of earth, or twice as far as the moon while the tip of the hair would be about twice as far from Earth.
He said: “If we could pinpoint the location of the root of these hairs, we could potentially send a probe there and get a bonanza of data about dark matter”.
The dark matter can not interact through the electromagnetic force, does not move around that much, does not emit nor interact with light and has a gravitational pull in action.
The findings reveal that if researchers can find the root of these hairs, it may be possible to detect dark matter a bit more easily.
Both dark matter and dark energy are yet to be directly found, but experiments are underway to unlock their mystery, such as dark matter from space or the planet’s deep underground.
Galaxies, which contain stars made of ordinary matter, form because of fluctuations in the density of dark matter.
The hairs would have “kinks” in them that correspond to the transitions between the different layers of Earth.
Fine-grained streams of dark matter mixed up with matter matter are crisscrossing through our solar system as we speak.

Charles Lawrence, chief scientist at NASA’s Jet Propulsion Laboratory’s astronomy, physics and technology directorate, said that dark matter had been studied for over 30 years, but had still evaded investigation of any worth. With that said, further study is needed in order to better understand these hairs.
