Considering that dark matter comprises about 85% of our Universe, even though it’s almost undetectable apart from the gravitational force it exerts, it comes as a bit of a surprise the recent news that dark matter could be giving Earth a dark matter wig made out of a lot of long dark matter filaments.
Dark matter is one of the most elusive things out there, mainly because it has no connection to light what-so-ever> It doesn’t produce light and it doesn’t interact with it in any way. The only method through which we can ascertain its existence is the gravitational force it applies to everything around it.
Because of the reason it is almost everywhere in our universe, it’s to no surprise that dark matter is around our planet as well. This matter is theorized to create a sort of stream similar to our rivers that flow throughout the universe, encircling solar systems in something that could be described as a halo.
But the fact that it may interact with Earth might come with a bit of a shock. Dark matter would basically hit our planet and disperse itself in strands of dark matter, similar to strands of hair. This dark matter “wig” would start around 600.000 miles away from ground level, roughly two times the distance from our Moon to our ground. Because it has virtually no effect on regular matter, these strands would basically just sit there after hitting our planet, flowing like a massive body of hair through space.
These findings were achieved at the NASA Jet Propulsion Laboratory located in Pasadena in the state of California. A simulation was made with the use of a computer in order to see how these particle strands of dark matter would form if they hit an object like our Planet. The roots of the hairs forming the wig would be the densest part of the strand and it would be created when the stream of dark matter hits the center of our planet. If this simulation would be applied to another planet, take Jupiter for instance, the roots would be roughly one trillion denser than the ones encircling our Earth.
If scientists would be able to find the exact location of such dark matter roots and send probes in order to study them, the findings we would attain concerning dark matter would be invaluable. But that dream is still a long way off, unfortunately.
But the possibility that dark matter could be giving Earth a dark matter wig could as well be fact, considering the mysteries that still surround dark matter up to this day. In order to elucidate these mysteries, science will have to advance further.
