Einstein's theory of general relativity emerged from one of its most difficult challenges

Einstein's theory of general relativity, proposed more than a century ago, once again emerged from a difficult test in a study of supernovae.

The theory published by Albert Einstein in 1916, general Relativity, changed our understanding of physics and the universe. This theory defines gravity as a consequence of space-time flexibility: massive objects distort space-time and create depressions around which other objects revolve. They have tested the general and continue to try to find situations in which relativity is unresponsive, but not a single case has been found.

In a new study, the results of December 13 Published in the journal Physical Review X, the researchers report the results of one of the most ambitious and challenging challenges to general relativity. They analyzed observations of a dual supernova system made over 16 years by seven different radio telescopes around the world from 2003 to 2019.

  • Einstein's general relativity was reaffirmed by simulating black hole jets. These rays are continuous, but due to the rotation of the star, they seem to fluctuate, and their naming is based on this. This light is only visible when a pole is pointing toward the Earth. one spin spins 44 times per second and the other completes one spin every 2.8 seconds. According to members of the research team, the two objects orbit a common center of mass once every 147 minutes, and each of them travels in space at a speed of about 1 million kilometers per hour.

    Quality matched quantity: The research team noted that this study achieved levels of accuracy that were unprecedented for testing general relativity. "Apart from gravitational waves and light scattering, the precision used in the experiment also allows us to measure the effect of time dilation, which makes clocks work slower in gravitational fields for hours," Manchester said. "We even have to consider Einstein's famous equation E=mc ^ 2 when examining the effect of electromagnetic radiation emitted by fast-spinning supernovae on their orbital motion."

    This study showed that all seven predictions tested Proved and thus general relativity remains unbreakable. But that does not mean that researchers should stop trying to find fault with it. "General relativity with other forces," said Robert Ferdman, co-author of the study from the University of East Anglia in England. The foundation described by quantum mechanics is not compatible. Therefore, it is important to carry out the most rigorous experiments on it as possible to find out how and when this theory fails. "

    " "It is a great discovery that opens the door to new physics beyond our current theoretical understanding of the universe, and may ultimately help us discover a single theory of the fundamental forces of nature."
