A wobble from Mars could be sign of dark matter (phys.org)
In a new study, MIT physicists propose that if most of the dark matter in the universe is made up of microscopic primordial black holes—an idea first proposed in the 1970s—then these gravitational dwarfs should zoom through our solar system at least once per decade.
