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

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

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."

The universe’s hidden mass may be made of black holes, which could wobble the planets of the solar system when they pass by

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.
