New Gravitational Wave Research May Finally Reveal Mysterious “Dark Matter”
One breakthrough in physics may lead to another.
Black Holes and Revelations
Based on a new study, the same equipment that was integral to the work of this year’s winners of the Nobel Prize for Physics — gravitational wave detectors — might be able to provide valuable insight into another enigmatic field of research: dark matter.
“The nature of dark matter is one the greatest mysteries in physics,” the study’s co-author Emanuele Berti noted in a University of Mississippi news release. “It is remarkable that we can now do particle physics – investigate the ‘very small’ – by looking at gravitational-wave emission from black holes, the largest and simplest objects in the universe.”
Berti and an international team of researchers produced calculations that suggest that some kinds of dark matter could form clouds around black holes. The going theory is that these clouds emit gravitational waves that could be detected by certain advanced equipment. “Surprisingly, gravitational waves from sources that are too weak to be individually detectable can produce a strong stochastic background,” explained co-author Richard Brito.
Based on their research, which has been published in Physical Review Letters, the scientists believe close analysis of data collected by the Laser Interferometer Gravitational-Wave Observatory (LIGO) could confirm or deny the presence of ultralight dark matter.
Dark Matter Matters
Dark matter is estimated to be five times as abundant as ordinary matter, and yet, no one has been able to directly detect it. It has the potential to unlock all kinds of secrets about the universe, so the great amount of interest in this topic by scientists and astrophysicists isn’t surprising.
Already, this interest has led to new theories on the properties of dark matter and projects like the Large Synoptic Survey Telescope, an immensely powerful digital camera set to go online in 2020. Recently released results from the Dark Energy Survey were even said to have the potential to rewrite physics as we know it.
If Berti and the rest of his team are correct in their belief that gravitational wave detectors will allow us to finally “see” dark matter, the implications would be tremendous. As Brito noted, “This is a new, exciting frontier in astroparticle physics that could shed light on our understanding of the microscopic universe.”
