An MIT study suggests that primordial black holes could be dark matter and might cause detectable wobbles in Mars' orbit.

According to a new study, if a primordial black hole passed within a few hundred million miles of Mars, it could shift the planet's orbit by about a meter -- causing a "wobble." ...
