The latest research shows Einstein’s gravitational theory of relativity has been proven correct

Bisnis.com, JAKARTA – Recent research analyzing the largest map of the universe has found evidence that Einstein’s theory has been reconfirmed regarding gravity and the structure of the universe.

Reporting from live science, the analysis, which looked at nearly 6 million galaxies and quasars over 11 billion years of cosmic time, found that gravitational forces behaved as predicted by Albert Einstein’s general theory of relativity, even on very large scales.

These results confirm cosmologists’ main theories about the universe and seem to rule out other theories about gravity, the researchers said.

The researchers published their findings in several papers on the arXiv preprint server and will present them in January at the American Astronomical Society meeting in National Harbor, Maryland.

“General relativity has been tested very well on the scale of the solar system, but we also need to test whether our hypotheses work on much larger scales,” said Pauline Zarrouk, a cosmologist at the French National Center for Scientific Research. (CNRS) accepted. part in the research.

“Studying the rates of galaxy formation allows us to test our theory directly and, so far, we are in line with the predictions of general homogeneity on cosmological scales. he added.

Cosmologists have long debated the behavior of gravity at great distances. The leading theory, called the lambda cold dark matter model, builds on Einstein’s theory to offer the most comprehensive view of a wide range of astronomical phenomena.

But there are doubts about some of the elements in the model, such as dark matter and dark energy – two mysterious entities that do not interact with light but account for most of the mass and energy of the universe – as well as the inability of the model to predict some ideas, has led competing groups to fight for alternative explanations.

One of these is Modified Newtonian Dynamics (MOND), which suggests that for gravitational pulls that are 10 trillion times smaller than those felt on Earth’s surface, such as the pull between distant galaxies, that Newton’s laws (which form the basis of general relativity) no longer apply. and must be broken. substitute another equation.

To trace how gravity behaves on a large scale, the researchers turned to data from the first year of the Dark Energy Spectroscopy Instrument (DESI) mounted on the Nicholas U. Mayall 4-meter telescope in Arizona, which marked the position of depression months. millions of galaxies to learn how the universe expanded until today.

The scientists performed a “full-form analysis” that produces a precise measure of the growth of the galaxy’s structure over time. This research shows that, although dark energy may evolve over time, the structure of the universe closely matches the predictions made by Einstein’s theory.

It is too early to say with certainty what this means for our overall view of the cosmos, but the data collected by DESI over the next two years will be published in the spring of 2025.

The trial, now in its fourth of five years, will include data collected by DESI. data from about 40 million galaxies and quasars at that time ended up. If the answer is readily available, we may not have to wait too long to find it.
