General relativity has probably endured the most difficult task to date.
theory, Albert Einstein Published in 1916, it revolutionized the understanding of physics and the universe.I will explain gravity As a result of space-time flexibility: giant objects distort space-time, creating depressions around which other objects orbit.
Scientists General theory of relativity Over the last 105 years, we have repeatedly tested to find out what is missing or what is happening. They haven’t found it yet.
In a new study, researchers report the results of one of the most ambitious and involved. Challenge to general relativity So far started. They analyzed the observations of the double pulser system made by seven different radio telescopes around the world from 2003 to 2019.
Pulsar is a kind Neutron star, Or ultra-dense stellar corpses, emitting powerful radiant beams and particles from their magnetic poles. These beams are continuous, but they look pulsed (hence the name) because the pulsar is rotating. This light can only be seen if the poles are pointed at the earth.
The Pulsar The pair investigated by the research team is about 2,400 light-years away from Earth. One of the pulsars spins 44 times per second, while the other spins once every 2.8 seconds. According to team members, the two objects orbit a common center of gravity once every 147 minutes, each traveling in space at 620,000 mph (1 million km).
“Such fast orbital motion of compact objects like these-they are about 30% larger than the Sun, but only about 24 kilometers. [15 miles] In a statement, Dick Manchester, research co-author of the Federal Institute for Science and Industry Research (CSIRO), Australia’s national scientific institution, can test various predictions of the general theory of relativity.
And quality was consistent with quantity: the study achieved an unprecedented level of accuracy for the general theory of relativity test, team members said.
“Others Gravitational waves “We can also measure the effect of a” time dilation “that slows the clock in a gravitational field by propagating light,” said Manchester. “Consider Einstein’s famous equation E = mc ^ 2. The effect of electromagnetic radiation emitted from a fast-rotating pulsar on orbital motion. “
The study found that all seven predictions tested were supported. Therefore, the general theory of relativity remains undefeated — but that does not mean that researchers should stop trying to find cracks in it.
“General theory of relativity is incompatible with others Basic power, Described by quantum mechanics. Therefore, it is important to continue the rigorous testing of general relativity as much as possible to discover when and how the theory collapses, “co-authored physicist at the University of East Anglia. Robert Ferdman said in the same way. statement.
“Finding deviations from the general theory of relativity will constitute a major discovery that will open a new window of physics beyond the current theoretical understanding of the universe,” Feldman added. “And it may help us towards finally discovering a unified theory of the fundamental forces of nature.”
The new study was published in the journal Physical Review X on Monday (December 13th).
