"Earth's Orbit Altered by Ancient Black Holes Passing Every Decade"

A new study suggests that ancient black holes, known as primordial black holes (PBHs), may be passing through our cosmic neighborhood every decade, potentially altering the orbits of planets and moons in our solar system. These PBHs, believed to be made primarily of dark matter, could cause subtle changes in the distances of celestial bodies from the sun or from Earth. While detecting these effects would provide evidence of the existence of PBHs, it poses a significant challenge due to the need for more precise simulations and higher-quality observations.
