Scientists working at the world’s biggest experiment Large Hadron Collider (LHC) near Geneva reckon they may have found the last piece of the jigsaw that explains how the universe works.
Physicists working at world’s biggest experiment, CERN’s Large Hadron Collider said that they had discovered a new subatomic particle that looks for all the world like the Higgs boson, a potential key to an understanding of why elementary particles have mass and indeed to the existence of diversity and life in the universe.

LHC is a 27 mile tunnel deep under the border between France and Switzerland, the Large Hadron Collider (LHC) was built to recreate the conditions of the Big Bang, when the universe started and to find the Higgs boson. The LHC costs about around 10 billion USD to build and involved 10,000 scientists from around 100 countries.
Scientists all over the world are searching for existence of this particle for around 50 years.
“I think we have it,” Rolf-Dieter Heuer, the director general of CERN, said in an interview from his office outside Geneva, calling the discovery “a historic milestone.” His words signalled what is probably the beginning of the end for one of the longest, most expensive searches in the history of science. If scientists are lucky, the discovery could lead to a new understanding of how the universe began.
”Seeing something new is really the beginning of this long journey to understand what on Earth it is that you have seen,” Tara Shears, who works on the LHCb detector at Cern, said. “It’s like turning up to a railway station to pick someone up who you’ve never met before. You arrive at the station, the train comes in, and there’s someone standing on the platform. You’re guessing it’s them, but you’re not going to know until you walk up and check who they are.”
Scientists have already cautioned that the discovery may not answer all the questions they have about pressing mysteries in nature.
“I find it a very depressing prospect, the possibility that this may be the last great discovery for many decades,” Prof. Weinberg added.
Nonetheless, the scientific world was in agreement that the discovery was of major importance.
In an interview with the BBC on Wednesday, Mr. Hawking, who has motor neurone disease, said: “This is an important result and should earn Peter Higgs the Nobel Prize. ”If the decay and other interactions of this particle are as we expect, it will be strong evidence for the so-called standard model of particle physics, the theory that explains all our experiments so far,” Mr. Hawking said. ”But it is a pity in a way because the great advances in physics have come from experiments that gave results we didn’t expect. For this reason I had a bet with Gordon Kane of Michigan University that the Higgs particle wouldn’t be found. It seems I have just lost $100.”
British physicist Peter Higgs arrives for the opening of a seminar to deliver the latest update in the 50-year bid to explain a riddle of fundamental matter in the search for a particle called the Higgs boson at the European Organization for Nuclear Research (CERN) in Meyrin, near Geneva.
The find was hailed across the globe, with renowned British physicist Stephen Hawking calling for the man who lent his name to the particle, Peter Higgs, to be given the Nobel Prize.
After the initial excitement, however, scientists are embarking on a long journey to confirm the particle is indeed the Higgs boson — and if so, exactly what form it takes.
WHAT IS THE GOD PARTICLE?
The Higgs boson is frequently referred to as ‘the god particle’, a name adopted after Leon Lederman’s book. Nobel Prize-winning physicist Leon Lederman, the Higgs boson is a particle believed to bestow mass on all other particles.
The Higgs boson is a type of elementary particle within the Standard Model of particle physics. It plays a key role in modern scientific theories of the universe and its existence or non-existence is considered pivotal in determining which theories about the nature of the physical universe are more likely to be correct.In particle physics, a boson (named for physicist Satyendra Nath Bose)
The existence of the Higgs boson was predicted in 1964 to explain the Higgs mechanism—the mechanism by which elementary particles are given mass. While the Higgs mechanism is considered confirmed to exist, the boson itself—a cornerstone of the leading theory—had not been observed and its existence was unconfirmed. Its tentative discovery in 2012 may validate the Standard Model as essentially correct, as it is the final elementary particle predicted and required by the Standard Model which has not yet been observed via particle physics experiments.
