A 16-year study looked for an error in Einstein’s theory of relativity: What is the verdict?

Over the past 16 years, an international team of astronomers has been working on a study that has analyzed a pair of pulsars called PSR J0737-3039A/B. Pulsars are types of rotating neutron stars that regularly pulsate in space and are a source of electromagnetic radiation.

The researchers note that they can observe relative effects that correspond to their pulse rate. This discovery was predicted in the past by Albert Einstein, in his theory of relativity. Scientists once again proved that the lifelong work of one of the most famous scientists in the world was correct, writes the portal Science alert.

“We have looked at a group of compact stars that are an ideal target for testing our scientific theories. Pulsars are objects around which we can find a strong magnetic field,” said astrophysicist Michael Kramer.

Scientists have studied one part of Einstein’s theory of relativity, which is the energy carried by gravitational waves. So far, their research has yielded the most accurate results in the field. For astronomers, pulsars are the most useful stars in the galaxy. Their pulses are rays of energy emitted from the poles of the star. These pulses are repeated with great accuracy and therefore we can use them in the future, for example, for navigation.

but that is not all. Pulzary Astronomers also use it to study space and the force of gravity. Pulsars, which helped scientists reconfirm relativity 16 years later, were discovered in 2003. It is about 2,400 light years from Earth. This binary system is the only one we’ve discovered made of two pulsars next to each other.

This is why it has become an ideal target for testing Einstein’s theory of relativity. The researchers called the system a “non-competitive lab.”

Einstein’s work reaffirmed

The two pulsars are very close to each other and orbit each other once every 147 minutes. One star rotates on its axis at up to 44 revolutions per second, while the other is younger and a little “slower”. It rotates on its axis once every 2.8 seconds. Pulsars are types of stars that are small, dense, and have a strong gravitational field. When two people are close to each other, they can affect each other’s impulses.

This is the effect that scientists have been trying to observe for 16 years. Not only did they discover the delay of light, due to the large distortion of spacetime, but they also discovered that the light is deflected by 0.04 degrees. In 16 years, researchers have performed seven tests of general relativity. All results fit this theory.

In the coming years, as new-generation telescopes enter space, scientists will conduct more demanding tests of the general theory of relativity. Their goal is to find some bugs.

“General relativity does not cooperate with other fundamental forces described by quantum mechanics. So it is necessary for us to test this theory as much as possible,” said astrophysicist Robert Friedman.

If scientists find a flaw in Einstein’s work, it would be a really cool discovery, Which may lead to the discovery of new physical laws.
