A wobble from Mars could be sign of dark matter

MIT physicists propose that if most of the dark matter in the universe is made up of microscopic primordial black holes, then these gravitational dwarfs 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.

The team 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.

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.
