Primordial Black Holes Can Produce Detectable Vibrations in Stars

According to new study scientists may be able to spot evidence of elusive dark matter by watching for ripples on the surfaces of stars. Such vibrations could indicate that a strange, hypothetical dark-matter object known as a primordial black hole has passed through the stars. The ripples could thus provide observable proof of dark matter, which is thought to make up more than 80 percent of all matter in the universe but has thus far evaded direct detection. Scientists think that the new study could help to better understand what dark matter is. They simulated what would happen if a primordial black hole passes through a star.

Primordial black holes which are theoretical remnants of the Big Bang, are much smaller than “normal” black holes  and thus would not swallow up a star and all of its light. Rather, their collisions with stars would cause noticeable vibrations on the stars’ surfaces. According to lead author Michael Kesden of New York University now that they know primordial black holes can produce detectable vibrations in stars, they could try to look at a larger sample of stars than just our own sun.
