Scientists near Chicago believe they are getting closer to discovering the existence of a new natural force.
Scientists discovered more subatomic particles
They discovered more evidence that subatomic particles known as muons are not behaving as predicted by current subatomic physics theory.
Scientists believe that the muons are being influenced by an unknown force. More data will be required to confirm these findings, but if they are, it could signal the start of a physics revolution.
All of the forces we encounter on a daily basis can be divided into four categories: gravity, electromagnetism, the strong force, and the weak force. These four fundamental forces govern the interactions of all objects and particles in the Universe.
The discoveries were made at Fermilab, a particle accelerator facility in the United States. They build on results announced in 2021, when the Fermilab team first proposed the existence of a fifth natural force.
According to Dr Brendan Casey, a senior scientist at Fermilab, the research team has gathered more data and reduced the uncertainty of their measurements by a factor of two since then.
“We’re really probing new territory. We’re determining the (measurements) at a better precision than it has ever been seen before.”
In the experiment known as ‘g minus two (g-2),’ researchers accelerate subatomic particles known as muons around a 15m-diameter ring, where they are circulated 1,000 times at nearly the speed of light.
The researchers discovered that they may be behaving in ways that cannot be explained by the current theory, known as the Standard Model, due to the influence of a new natural force.
Despite strong evidence, the Fermilab team has yet to obtain conclusive proof.
They had hoped to have it by now, but uncertainties in what the standard model says the amount of wobbling in muons should be have increased due to theoretical physics developments. In essence, the experimental physicists’ goalposts have been shifted.
The researchers believe they will have the necessary data and that the theoretical uncertainty will have narrowed sufficiently in two years for them to achieve their goal. However, a rival team at Europe’s Large Hadron Collider (LHC) is hoping to be the first to arrive.
Dr. Mitesh Patel of Imperial College London is one of thousands of physicists working at the LHC to discover flaws in the Standard Model.
He told that the discovery of experimental results that contradict the standard model would be one of the greatest physics breakthroughs of all time.
