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

Black holes the size of an atom that contain the mass of an asteroid may fly through the inner solar system about once a decade, scientists say. Theoretically created just after the big bang, these examples of so-called primordial black holes could explain the missing dark matter thought to dominate our universe. And if they sneak by the moon or Mars, scientists should be able to detect them, a new study shows.

    If dark matter is fully explained by such black holes, their most likely mass, according to some theories, would range from 1017 to 1023 grams—or about that of a large asteroid.

    In case this doesn’t tell you a lot, 1017 grams is half the weight of Mount Everest, and 1023 grams is 4x the weight of the Antarctic ice shield.
