Scientists have long hoped to find ‘flaws’ in the major theory of physics, but “General Relativity” again turned out to be a strong bone to break.
Since when Albert Einstein formally proposed his theory of relativity in 1916, it has resisted everything that scientists have challenged, even though it has been attempted to disprove the fact that gravity, which we know, is only a “distortion of the time-space fragment caused by massive objects” which are released in it ”.
This theory has perfectly described the observation of stars passing near the “super-massive” black hole at the center of our Milky Way galaxy, or the existence of gravitational waves, the discovery of which won the 2017 Nobel Prize in Physics.
Scientists already say that the theory of relativity has passed another test with excellent grades, such as the observation of the dual ‘pulsar’ system made by different telescopes of the world over 16 years.
According to researchers led by Michael Kramer of the Max Planck Institute of Radio Astronomy in Germany, the observed effects are consistent with the general theory of relativity by at least 99.99%.
Pulsars are fast-rotating, high-magnetism neutron stars that emit electromagnetic radiation from poles in opposite directions.
These objects are extremely compact and can accept within a sphere the size of a city, a mass larger than the Sun, say the researchers.
Although the light emitted by these cosmic objects is stable, their light rod does not match the axis of rotation of the pulsar.
Hence from the point of view of the earth it seems as if they have a beating light from very fast rotation. For this reason they are often compared to seeds.
Neutron stars are like a kind of ideal cosmic laboratory for testing the theory of relativity, because of their large gravitational influence.
Only black holes are denser and can exhibit extreme effects of general relativity, but pulsars are easier to observe thanks to their flashing light and radio signals.
In their study, astronomers targeted a unique pair of binary pulsars, 2,4000 light-years away, in the constellation Puppis.
One of them rotated around itself 44 times per second and the other more slowly, with full rotation around its axis every 2.8 seconds.
From 2003 to 2019, seven radio telescopes observed the dual pulsed system by calculating factors such as gravitational waves, light scattering, time delay, and mass-energy equivalence (E = mc2).
“We have to find ways to test Einstein’s theory, and fortunately the cosmic laboratory known as the ‘dual pulsar’ was discovered with the Parkes telescopes in 2003. Our observations of 16 years were in line with the general theory of relativity. Einstein, ”said Dr. Dick Manchester, CSIRO co-researcher.
“We will be back in the future with new radio telescopes to find weaknesses in the theory of relativity, and perhaps this will lead to a better gravitational theory,” said Adam Deller, a professor at Swinburne University and the ARC Center. for Gravitational Waves (OzGrav). / ZMEScience / Prepared by Andi Lamko /
