The Particle that Started the Big Bang
In 2013, the Nobel Prize for Physics was awarded to Francois Englert and Peter W. Higgs for their discovery of a particle that is vital to our understanding of the universe. Although its official name is the Higgs boson, many refer to it as the God particle, because it’s considered to be the building block of the universe. Many believe that the Higgs boson may be the cause for the Big Bang explosion which led to the creation of the universe. In the 1960s, Higgs came up with the concept that particles had no mass when the universe started. In a split-second, however, it came into contact with something that gave it mass. This, Higgs theorized, was the Higgs boson. Many scientists initially laughed at the idea, but in the upcoming years, Higgs along with Englert and several of their peers continued to work on these concepts. Their ideas would eventually help lead the way to the discovery of the Higgs boson decades later. The search for the Higgs boson certainly didn’t come up cheap, as it cost nearly $10 billion to build the machinery necessary to perform the tests to find it. Yet nearly every physicist would agree that it was worth it, as the Higgs boson has already been labeled as one of the most important discoveries in particle physics. The finding is also a huge boost for physics in general because it proves that the Standard Model of Physics which researchers have been using for years is correct. The Higgs was the last remaining question mark as all of the other particles and elements had been found. Still, many ordinary people may question how such a discovery affects their lives at all. Although quantum mechanics may seem weird, it has actually led to several important technological breakthroughs over the past century. These findings have led to laser and X-ray technologies that work in the real world. There is still much to be learned with further observation of the Higgs boson in action. Scientists hope to learn more about dark matter, a strange substance that constitutes 25 percent of the mass of the universe. The research could also lead to some other technologies as well.
