A fast hurricane of dark matter is approaching Earth at 310 miles per second, according to astronomers.
Very little is known about this occurrence, since the lightweight dark matter can't be seen nor felt.
Scientists - Matter - Exists - Movement - Placement
Scientists can only prove that the dark matter exists based on the movement and placement of a stellar stream, which has the fainting remnants of a smaller galaxy engulfed by the Milky Way.
Astronomers hypothesize that dark matter is traveling with the stellar stream through our solar system.
Matter - Harm - Earth
They also note that this dark matter won't cause any harm to Earth.
If astronomers' calculations are correct, the Solar System is right in the middle of a turbulent space event: a vast 'hurricane' of dark matter, blowing at an insane speed of 500 kilometres per second (310 mps).
Detection - Matter
We can't see it, and we can't feel it - but it could mean that a direct detection of dark matter is closer than we thought.
Dark matter is one of the big conundrums of the Universe. We have never directly detected it, and we don't know exactly what it even is - but we do know that it's out there. We can infer it based on the motions of the stars and galaxies, which are far too fast for the amount of observable mass.
Something - Mass - Gravity - Movements - Movements
So there's something else out there, some other mass creating the gravity to influence those cosmic movements. We can even, based on those movements, calculate that invisible mass. "Dark matter" - whatever that might be - is the name we give that mass, and scientists are working on ways to detect it directly.
But we're not there yet. So how do physicists know we're in the middle of a tremendous storm of dark matter? The clue lies in the motion of the stars.
