If microscopic black holes born a fraction of a second after the Big Bang exist, then at least one may fly through the solar system per decade, generating tiny gravitational distortions that scientists can detect.

Astronomers have observed three types of black holes in the universe. Stellar-mass black holes formed from the collapse of a massive star, intermediate mass black holes found in some star clusters, and supermassive black holes that lurk in the centers of galaxies.

Scientists say microscopic black holes could explain the elusive "dark matter" that makes up a quarter of all matter in the universe. But can it be proven?

A new study suggests that a microscopic black hole might pass through our solar system once every decade or so.

"Primordial black holes do not live in the solar system. Rather, they're streaming through the universe, doing their own thing," said researcher Sarah Geller.

Astronomers have proposed a bold new detector for dark matter: the planet Mars. We know the position of the Red Planet with exquisite precision and if there was a certain type of dark matter passing through the Solar System,
