Well, there is some good news to come out of a report from Business Insider - you haven't yet been killed by a black hole. The bad news is that it is actually more possible than we thought. Holes have been forming since the start of time, and all of them are hurtling towards us through space.

Some of these black holes could weigh as much as Earth's Moon, others like an asteroid, and everywhere in between. Whatever weight they have, most are probably going to be smaller than a typed period.

Astrophysicists are running out of ways to explain what the Universe is made up of. They do know that 80% is dark matter, which has a gravitations pull on the "other" 20% of the normal matter. But it has been invisible for more than 80 years and only recently have we discovered it.

There have been plenty of devices in space and underground that have been there solely to detect the dark matter, but they have turned up empty handed so far. Now researchers are turning to the motion that we are surrounded by 13.8-billion-year-old black holes.

"On the dark matter particle side of the spectrum, the range of possibilities is narrowing down quickly," Alexander Kashlinsky, a cosmologist at NASA, previously told Business Insider. "If nothing is found there, and nothing is found in the black hole theatre, then we may be in a crisis of science."

Now, they aren't betting on these black holes at all - not because they don't think something is there, but rather because they don't think they'll get it out. These holes are heavy, sometimes between 20 to 100 times the mass of the sun.

Tiny black holes might be harder to find because while they are heavy, they are extremely dense, which makes them small.

Still, they are important to find.

"Asteroid-mass black holes, if they were all of the dark matter, might pass through Earth once a millennium or so, but would be very, very hard to detect," Brandt told Business Insider. "If you had somebody right there, they might be able to observe one."

Brandt wasn't sure that these holes would be dangerous. "We certainly would notice if one passed near Earth, since it would affect the orbits of all of our satellites," he wrote in an email. "I imagine that it would mess up GPS for example."

The good news is that these mini-black holes, the ones that could mess things up, don't pass between Earth and the Sun all that often - about once every 100 million years.

"We would, on average, have to wait much longer than the age of the Universe for one to pass through Earth. Though such an event is absurdly unlikely ... It would cause some havoc," he wrote.

It still could cause some problems, Brandt noted, since it would be "a bit like a bullet, but with the damage being done by tidal forces deforming the object and generating intense heat"

Still, the scariest possibility is what these tiny holes would mean for science.

"It’s possible there is no interaction of dark matter [with normal matter] except through gravity," Brandt said. "If that’s the case, we’re in trouble. We’ve never come to that point where we know something is out there but is completely invisible to our experiments."
