Scientists claim they have observed a fifth force of nature that could transform our understanding of how the universe works.<\/span><\/p>\n

Researchers at the Hungarian Academy of Sciences have revealed results that could show it in action.<\/p>\n

They saw an excited, decaying helium atom emit light when the particles split in a strange way that could not be explained by the current understanding of physics.<\/p>\n

Hints of a fifth fundamental force have set the physics world abuzz. Researchers at the Hungarian Academy of Sciences have revealed results that could show it in action. The discovery could completely upend our understanding of the universe. Pictured is an image of the cosmic web<\/p>\n<\/div>\n

It was the second time lead scientist Attila Krasznahorkay and his team had seen the new particle they called X17.<\/p>\n

They found its mass to be 17 megaelectronvolts.<\/p>\n

Mr Krasznahorkay told CNN<\/a>: ‘X17 could be a particle, which connects our visible world with the dark matter.’<\/p>\n

STANDARD MODEL OF PARTICLE PHYSICS AND WHY THE FIND IS SO EXCITING<\/h3>\n
\n

The Standard Model says everything in the universe is made from the most basic building blocks called fundamental particles, that are governed by four forces: gravity, electromagnetic, weak nuclear and strong nuclear. <\/span><\/p>\n

\"The<\/p>\n<\/div>\n

The Higgs boson, named after professor Higgs (pictured), was discovered in 2012 and is an essential component of the Standard Model<\/p>\n<\/div>\n

The forces work over different ranges and have different strengths. <\/span><\/p>\n

This new particle, if it exists, would not fit into the description given by the Standard Model and so would lead to a whole new area of particle physics. Some have suggested it might even lead to the discovery of a fifth fundamental force.<\/span><\/p>\n

 This development is exciting because the Standard Model has left some questions unanswered for years, so scientists are keen to break free of it and find new theories.<\/span><\/p>\n

It can’t explain gravity, for example, because it is incompatible with our best explanation of how gravity works – general relativity, nor does it explain dark matter particles.<\/span><\/p>\n

The quantum theory used to describe the small particles in the world, and the general theory of relativity used to describe the larger objects world, are also difficult to reconcile. <\/span><\/p>\n

Nobody has managed to make the two mathematically compatible in the context of the Standard Model.<\/span><\/p>\n

According to the Big Bang theory, matter and antimatter were created in equal amounts at the start of the universe and so they should have annihilated each other totally in the first second or so of the universe’s existence.<\/span><\/p>\n

This means the cosmos should be full of light and little else. <\/span><\/p>\n

But because it isn’t there must have been a subtle difference in the physics of matter and anti-matter that has left the universe with a surplus of matter and that makes up the stars we see, the planet we live on and ourselves.<\/span><\/p>\n

But the observations seen so far are not enough to confirm the existence of a particle.<\/span><\/p>\n<\/div>\n<\/div>\n

Professor of physics and astronomy at the University of California, Irvine, Jonathan Feng, who has closely watched the Mr Krasznahorkay’s team’s efforts, said it could be a ‘game changer’, adding if it could be replicated, ‘this would be a no-brainer Nobel Prize’.<\/p>\n

It comes three years after the Hungarian team spotted an anomaly in radioactive decay, suggesting the existence of a new particle.<\/span><\/p>\n

If their tests prove accurate, the discovery could completely upend our understanding of how the universe works.<\/span><\/p>\n

The current working model of physics states that there are four fundamental forces of nature: gravity, electromagnetism, and the weak and strong forces between atoms.<\/span><\/p>\n

The 2016 experiment by Mr Krasznahorkay and his team of physicists suggested there was another force.<\/span><\/p>\n

The team said at the time that they had found a bizarre radioactive decay irregularity, according to a report by Nature News.<\/a><\/span><\/p>\n

They published their results in late 2015 in the prestigious Physical Review Letters.<\/span><\/p>\n

Despite the radical claim, their paper received very little attention, according to a report in Gizmodo<\/a>.<\/span><\/p>\n

That is, until physicists at the University of California checked their method and results \u2013 and found the study to be accurate.<\/span><\/p>\n

‘What it’s telling us if it is correct is that there is something going on in the way that one particle talks to another particle that we haven’t got inside our mathematics at the moment,’ Geraint Lewis, a professor of astrophysics at the University of Sydney told ABC News<\/a> at the time.<\/span><\/p>\n

Scientists have theorised that a fifth force exists for decades.<\/span><\/p>\n

They claim it could help explain the inability of the standard model of particle physics to explain dark matter.<\/span><\/p>\n

Dark matter is invisible substance thought to make up more than 80 per cent of the universe’s mass.<\/span><\/p>\n

Theorists have proposed a number of exotic-matter particles, including ‘dark photons’, that carry the electromagnetic force.<\/span><\/p>\n

The Hungarian scientists were looking for dark photons by blasting protons at a thin strip of lithium.<\/span><\/p>\n

As the lithium absorbed the protons, it transformed into an unstable version of beryllium, which decayed even further, creating electrons and positrons.<\/span><\/p>\n

When the protons hit against the lithium at 140 degrees, more electrons and positrons were created than were expected.<\/span><\/p>\n

Krasznahorkay suggested this extra material was being created by a particle that was 34 times heavier than the electron.<\/span><\/p>\n

‘We are very confident about our experimental results,’ said Krasznahorkay at the time, adding that the team had repeated its test several times.<\/span><\/p>\n

But many scientists were sceptical of the claim.<\/span><\/p>\n
