Astrophysicists will determine the expansion rate of the Universe using gravitational waves

(ORDO NEWS) –Researchers at the Indian Scientific Cooperation (LISC) recently analyzed the detected gravitational waves to measure the expansion rate of the universe.

In 1929, the famous astronomer Edwin Hubble suggested that the universe was expanding and galaxies were moving away from us. This laid the foundation for understanding the origin of our universe and its evolution. Researchers have now measured the rate at which the universe is expanding thanks to gravitational waves that were recently detected.

An international team of researchers analyzed recently discovered gravitational waves to estimate the rate of expansion of the universe, known as the Hubble constant.

Gravitational waves are invisible ripples in space that were first discovered by Albert Einstein over 100 years ago. The 35 recently discovered gravitational waves bring the total to 90. 32 of these waves were detected from merging pairs of black holes, and three others were likely from a collision of a neutron star and a black hole.

Gravitational waves act like a siren in the universe, their distances can be determined by how loud they appear on detectors. An accurate measurement of the expansion rate of the Universe should show how quickly the galaxies in which these events are detected are moving away from us.

Scientists are confident that gravitational waves may be one of the most effective tools that can be used to determine the rate of expansion of the universe. This will not only help to more accurately understand and analyze gravitational waves, but also help find elusive dark energy.

The LIGO and Virgo observatories are currently undergoing modernization ahead of the forthcoming fourth observation cycle, which is expected to begin towards the end of 2022.
