There are many things that serve as a global threat.
Most of them have to do with corrupt institutions and rogue governments.
But Earth could be in serious jeopardy from one mysterious threat.
According to a study, the Earth is currently in the midst of what’s called a dark matter hurricane.
Dark matter particles are blowing at an immense speed through our solar system.
The ramifications of this have some scientists at odds.
Some see it as an opportunity to study dark matter, which has been theorized to comprise 85% of the universe.
Research enthusiasts who subscribe to this theory want to conduct experiments on dark matter, which is both invisible and weakly interacting with observable physics measures such as light and electromagnetism.
Thus far, dark matter is only thought to interact with gravitational forces, albeit nominally.
However, one physicist believes that dark matter could be responsible for the extinction of the dinosaurs.
In an interview, Harvard physicist Lisa Randall said:
My collaborators and I suggest that dark matter might ultimately (and indirectly) have been responsible for the extinction of the dinosaurs. We know that 66 million years ago, an object at least 10 kilometers wide plummeted to Earth from space and destroyed the terrestrial dinosaurs, along with three-quarters of the other species on the planet.
The object Randall is referring to is either a comet or an asteroid.
She essentially goes on to argue that an accumulation of dark matter in the solar system could’ve been responsible for directing such a comet or asteroid towards Earth.
“Its gravitational pull could be powerful enough to dislodge comets at the outer edge of the solar system…The errant comets would then be ejected from the solar system or…be redirected to hurtle toward the inner solar system, where they might have the potential to strike the Earth.”
An asteroid at least six miles wide would be devastating for life on the planet.
Even more terrifying, there are asteroids as big as 600 miles that have a chance—though minuscule—of slamming into Earth.
Something that size could trigger an extinction-level event and the prevalence of dark matter could potentially tick up those odds a small bit.
The general scientific consensus on dark matter is that it doesn’t pose a major threat and could help us grasp a better understanding of the universe.
In a broader sense, greater knowledge pertaining to threats from outer space is a good thing.
NASA has already begun working on better protocols for detecting asteroids.
As our understanding grows, so does our preparedness.
The ultimate goal would be able to find ways to divert a harmful asteroid if it did enter our solar system and threaten us with impact.
Studying dark matter could potentially get us one step closer to achieving that goal.
