New research shows that our planet earth may possess a series of dark matter filaments.
The universe may have what is termed “hair” growing in its subtext. A study by Gary Prézeau of NASA's Jet Propulsion Laboratory, Pasadena, California, proves that the existence of long filaments of dark energy is a possibility.

According to this study, published this week in the Astrophysical Journal, these filaments of hair are mysterious and invisible to the naked eye. Yet the fact is they make up 27% of the matter and energy in the known universe. The so-called visible matter makes up a mere 5% of the universe and is thus an infinitesimal part of reality. Thus reality is very complex.
The dark energy is actually connected to the expansion of the universe. It figures in the phenomenon of acceleration. We have never seen dark matter or dark energy. They are both hypothetical concepts only postulated due to the effects we notice on a regular basis. There are many experiments that are taking place which try to prove their existence though.

On the basis of the gravitational pull of dark matter, many scientists are sure it exists. The measurements are up to 1% as of now though. It will take a long time for science and scientists to plumb this strange phenomenon of nature and the universe.
Dark matter is said to be cold, meaning that it doesn’t interact and is inert. And it shuns all light, thus the name “dark” which is attached to it. Galaxies made of normal matter turn out to have dark matter which took part in their formation.
The variations in the density of this dark matter are what gave rise to normal matter. And gravity is the binder that holds dark matter and ordinary matter together in tandem. In the 90s, a series of experiments proved that dark matter forms fine-grained streams of particles. A stream can be bigger than the entire solar system.

Our galaxy contains many such streams of dark matter. They probably look like hair although no one has seen one. And their formation is like a mixture of two flavors of ice cream (so to say in a metaphorical manner). A swirl of these two flavors will get you a pattern of lines that intertwine and spiral in unison.
With the aid of gravity the streams interact with each other. When a stream enters the vicinity of a planet, the result is its distribution into a series of fine hair-like filaments. And dark matter can go right through our planet. The dark matter hair has roots and tips too.
"Dark matter has eluded all attempts at direct detection for over 30 years. The roots of dark matter hairs would be an attractive place to look, given how dense they are thought to be," said Charles Lawrence, chief scientist for JPL's astronomy, physics and technology directorate.

A probe into this phenomenon may yield results as far as the presence of dark matter is concerned in the future.
