Nationalgeographic.co.id—Researchers at the University of East Anglia and the University of Manchester have helped conduct experiments for 16 years to challenge general theory of relativity Einstein. The international team studied a pair of extreme stars called pulsars through seven radio telescopes around the world. Then they use it to challenge the theory Einstein the most famous with some of the most stringent tests.
The physics of gravity is described most accurately by general theory of relativity Einstein. However, failed attempts to unify gravity and quantum mechanics, describe nature on the largest and smallest scales, motivating the continuous search for possible deviations from the theory by rigorous testing through different experiments, from laboratory to astronomical observations. If deviations from that theory exist, they may be detectable in the strong gravitational fields of solid objects, such as neutron stars and black holes.
Studies that have been published in journals Physical Review X on December 13, 2021 entitled Strong-Field Gravity Tests with the Double Pulsar has revealed a new relativistic effect observed for the first time.
Dr Robert Ferdman, from the UAE School of Physics, said, “How successful general theory of relativity Einstein that has been proven, we know it’s not the last word in the theory of gravity. More than 100 years later, scientists around the world are continuing their efforts to find flaws in his theory. General relativity is incompatible with the other fundamental forces described by quantum mechanics. Therefore, it is important to continue to carry out the most rigorous tests of general relativity, to discover how and when the theory collapsed.”
Finding deviations from general relativity would be a major discovery that would open new windows of physics beyond our current theoretical understanding of the Universe. And it might help us eventually find a unified theory of the fundamental forces of nature.
Led by Michael Kramer of the Max Planck Institute for Radio Astronomy in Bonn, Germany, an international team of researchers from ten countries tested the theory. Einstein with the most stringent testing on the PSR J0737–3039A/B dual pulsar system which is an eclipse two-way binary system.
