Scientists may have discovered the fifth force of nature, according to a laboratory



It has long been recognized that there are four "fundamental forces" that govern nature.

The substance of our universe is collected or moved by those forces, which are determined by the fact that they do not appear to be reduced to more basic interactions between particles.

These include gravitational and electromagnetic forces that produce significant long-range interactions whose effects can be seen directly in everyday life.

And they also include forces known as strong interactions and weak interactions that produce forces at small, subatomic distances and manage nuclear physics.

There have been many unjustified allegations of the existence of a fifth major force over the years, and as a long hunt for dark matter continues to be futile, efforts to find new forces in the game to help fill in the gaps that the standard model of physics the particles can not explain have increased.

Dark matter is a theoretical substance hypothesized to make up about 85 percent of the total mass in the universe, but has not yet been observed.

But now scientists at the Hungarian Atomic Nuclear Research Institute believe they may have found more solid evidence of a hitherto unknown fifth major force of nature.

Attila Krasnahorkai and his colleagues at Atomki first reported some surprising results in 2015 after studying the light emitted during the radioactive decay of beryllium-8, an unstable isotope.

The discovery of beryllium-8 in the 1930s after the construction of the first particle accelerator in Cambridge, the existence of this unstable atom and the unique mode of its disintegration have been the focus of numerous studies, related to stellar nucleosynthesis – how nuclear fusion into stars forms elements.

In 2015, they discovered when protons were fired into the lithium-7 isotope, which creates beryllium -8, the subsequent decay of the particles did not exactly lead to the expected light emissions and a specific tiny "crack" appeared, which is an inexplicable reason. n, the electrons and positrons that decay when an atom decays are often ejected from each other at exactly 140 degrees.

Different guests in the same lab confirmed the results, and a year later the same experiment was repeated, with the same results in America.

It is believed that the moment an atom decays, excess energy among its constituents briefly creates a new unknown particle, which is then almost immediately decays into a recognizable positron and electron pair.

But not all of us are ready to be turned inside out or aligned in a different dimension. It is believed that an unknown particle, described as a "protophobic X boson", will carry a force that acts at microscopic distances not much greater than those of an atomic nucleus.

The boson is a particle that can carry forces.

The particle is named X17 because its mass is calculated at 17 mega-electron volts.

But Dr. Krasnahorkay now believes that they measured the same results in stable helium atoms, but instead of electrons and positrons in helium atoms separating 140 degrees, the angle is closer to 115 degrees.

"This characteristic is similar to the anomaly observed in 8Be and appears to be consistent with the boson X17 decay scenario," writes the team at arXiv where the study was published but has not yet been published subjected to inspection.

If the existence of particles is confirmed, this means that physicists will finally have to re-evaluate the interactions of the existing four fundamental forces of particle physics and make room for a fifth part.

"We expect more independent experimental results to come. for the X17 particle in the coming years, "the research team concluded in its paper.
