(ORDO NEWS) — Experts led by Michael Tobar from the University of Western Australia published the results of another experiment, which lasted 153 days. For the first time, a special tabletop gravitational wave detector was used. With its help, experts registered two unknown signals at once, which had not been possible to detect before.
This is reported by Science Alert.
Scientists noted the fact that the new device has quite a lot of differences when compared with the equipment that was used in many other observations. For example, in recent years, the Laser Interferometric Gravitational Wave Observatory (LIGO) has been looking for unknown signals. They use huge detectors that can be controlled with a special laser. They help to capture ripples that can occur in the structure of space-time.
The new study used a benchtop detector that uses the “chunk of ringing quartz” method. Michael Tovar noted that this equipment was designed specifically to detect small gravitational waves.
High-frequency waves are much more difficult to detect, so they must be studied. Short waves of this type can provide a lot of information at the cost of the development of the Universe, the Big Bang. If we talk about the sources of such waves, then they could well be some bosonic stars, as well as primordial black holes. Experts suggested that the recorded signals could also have been created by a mysterious substance – clouds of dark matter.
