Primordial black holes

An illustration of small primordial black holes. In reality, such tiny black holes would have a difficult time forming the accretion disks that make them visible here.

Tiny Black Holes May Leave Their Mark in Everyday Objects Here on Earth

An artistโ€™s illustration depicts a primordial black hole (at left) flying past, and briefly โ€œwobblingโ€ the orbit of Mars (at right), with the sun in the background. MIT scientists say such a wobble could be detectable by todayโ€™s instruments. Credits:Credit: Image by Benjamin Lehmann, using SpaceEngine @ Cosmographic Software LLC.

Mars’ Wobble Could Reveal Dark Matter, MIT Study Suggests

Artist's impression of a microlensing event caused by a black hole observed from Earth toward the Large Magellanic Cloud. The light of a background star located in the LMC is bent by a putative primordial black hole (lens) in the Galactic halo and magnified when observed from the Earth. Microlensing causes very characteristic variation of brightness of the background star, enabling the determination of the lens's mass and distance. Credit: J. Skowron / OGLE.
