MIT physicists propose that primordial black holes should zoom through our solar system at least once per decade.

A flyby like this, the researchers predict, would introduce a wobble into Mars ’ orbit, to a degree that today ’s technology could actually detect.

Such a detection could lend support to the idea thatPrimordial black hole black holes are a primary source of dark matter throughout the universe.

The researchers simulated various asteroid-mass black holes flying through the solar system.

They zeroed in on those flybys that appeared to be “close encounters,” or instances that caused some sort of effect in surrounding objects.

They found that if a primordial black hole were to pass within a few hundred million miles of Mars , the encounter would set off a slight deviation in Mars ’ orbit.
