Researchers challenged Albert Einstein’s famed theory of general relativity by observing stars known as pulsars for 16 years to seek a unified theory of the fundamental forces of the cosmos.<br/><br/>For more than 100 years, scientists have sought to find flaws in Einstein’s theory.<br/><br/>Scientists observed a double pulsar— consisting of two super-dense pulsars orbiting around each other — for 16 years to challenge Albert Einstein’s famous E=mc2 equation. (Max Planck Institute)<br/>Researchers in the United Arab Emirates and at the University of Manchester took recourse to seven radio telescopes stationed around the world. They used them to rigorously test Einstein’s famed E=mc2 equation. They revealed expected relativistic effects that were observed for the very first time.<br/><br/>According to Ferdman, “a pulsar is a highly magnetized rotating compact star that emits beams of electromagnetic radiation out of its magnetic poles. They weigh more than our sun and are only about 15 miles across; incredibly dense, that produce radio beams that sweep across the universe like a lighthouse.”<br/><br/>Ferdman said the team studied a double pulsar, which offers the best laboratory for testing Einstein’s theory, which he developed before the techniques to discover and study pulsars even existed.<br/><br/>The discovery of the double pulsar system is the “only known instance of two cosmic clocks which allow precise measurement of the structure and evolution of an intense gravitational field,” Benjamin Stappers, a professor of astrophysics at the University of Manchester, said.<br/><br/>Astronomer Ingrid Stairs of the University of British Columbia said the team tracked the radio photons emitted by one pulsar in the gravitation field of the companion pulsar.<br/><br/>Dec. 13, 2021<br/>Source: Max Planck Institute for Radio Astronomy<br/><br/>#Science #Einstein #Astronomy #Stars
