"If there are lots of black holes out there, some of them must surely pass through our backyard every now and then."

Tiny black hole "bullets" left over from the Big Bang could be passing through Mars at speeds in excess of 7,000 times the speed of sound, causing the Red Planet to "wobble."

A bold new study in Physical Review suggests that a wobble detected in Mars' orbit could be the result of dark matter made up of primordial black holes.

A new paper explores the idea of asteroid-sized objects that may be causing gravitational ripples in our cosmic neighborhood.
