Scientists could discover the fifth natural force, says the laboratory
It has long been recognized that nature is dominated by four "fundamental forces".
The essence of our universe is drawn together or separated by these forces, which are determined by the fact that they do not seem to be reducible to the basic interactions between particles. They include gravitational and electromagnetic forces that create significant interactions over long distances whose effects can be seen directly in everyday life.

And include forces known as strong interactions and weak interactions that create forces at small, subatomic distances and control nuclear physics.
Over the years, many unsubstantiated claims about the existence of the Fifth Basic Force have emerged and as a long hunt for dark matter continues to be unnecessary, efforts have been made to find new forces to help fill gaps that cannot explain the standard model of particle physics . l eft Created with Sketch.
Dark matter is a hypothetical theoretical matter that represents about 85% of all matter in the universe, but has not yet been spotted.
But now scientists at the Hungarian Atomki Institute of Atomki believe they could find more reliable evidence of the previously unknown Fifth Basic Natural Force.
Attila Krasznahorkay and his Atomki colleagues first reported some surprising results in 2015 after studying the light emitted during the radioactive decay of beryllium-8, an unstable isotope.
Since 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 way it disintegrates, has focused on numerous studies of stellar nucleosynthesis – like nuclear fusion in stars creates elements.
In 2015, they found that when protons were fired on the lithium-7 isotope, which forms beryllium -8, the subsequent decay of particles did not produce exactly the expected light emission and that specific tiny "bumps" would occur, meaning an unexplained reaction of n, electrons and the positrons that disintegrated when the atom disintegrated were often pushed together at exactly 140 degrees.
Various repeat tests in the same laboratory confirmed the results and a year later the same experiment was repeated with the same results in America.

It is assumed that when the atom breaks up, excess energy between its constituents briefly creates a new unknown particle, which then decomposes almost immediately into a recognizable positron and electron. pair.
But we are not all prepared from within or flattened into another dimension. Unknown particles, referred to as "protophobic X boson", are considered to carry a force acting at microscopic distances not much larger than the atomic nucleus.
A "boson" is a particle that can carry forces.
This particle was named X17 because its mass is calculated to be 17 megaelectrons.
But Dr. Krasznahorkay now believes they measured the same results in stable helium atoms, but instead of electrons and positrons in helium atoms that separate at 140 degrees, the angle was closer to 115 degrees.
"This feature is similar to the anomaly observed in 8Be and appears to be consistent in the X17 boson decomposition scenario," writes the team at arXiv where the research was published but has not yet been reviewed.
If the existence of a particle is confirmed, this means that physicists will finally have to reassess the interactions of the existing four fundamental forces of particle physics and make room for a fifth.
“We expect more independent experimental results. for the X17 particle in the coming years, ”concludes the research team in its work.
