A team of astrophysicists has suggested gravitational lensing of waves as a new way of measuring the expansion of the universe.
This phenomenon occurs when huge cosmic objects cause deformation in space-time. In this process, the cosmic waves that travel from near the object appear to bend.
This idea has been proposed by UC Santa Barbara theoretical astrophysicist Tejaswi Venumadhav Nerella and colleagues at the Tata Institute of Fundamental Research in Bangalore, India, and the Inter-University Center for Astronomy and Astrophysics in Pune, India.
For more than a century, scientists have been documenting evidence of the universe's expansion. Despite all of these scientific observations, it has been impossible to determine the exact rate at which celestial objects are moving away from one another.
The official release highlights that the pace of universe expansion has been susceptible to variations since its discovery due to measurement inconsistencies.
According to the most recent data, the expansion is occurring at a rate ranging from 67.4 to 76.5 kilometers per second per megaparsec. The recession velocity is measured in kilometers per second to the distance (in megaparsecs).
This disparity is known as Hubble tension, and some experts say it is a "crisis in cosmology."
The team suggests that this possible method may be used to estimate the universe's expansion.
