The ‘God Particle,’ Explained

[Editor’s note: Touch Mengheng is a student at the Massachusetts Institute of Technology and a researcher at the European Organization for Nuclear Research, which oversees the Large Hadron Collider. Scientists are using the Collider, a giant machine that smashes particles of matter together at high speeds, to help them prove the existence of the Higgs Boson, an elusive piece of matter thought to be behind much of what it currently understood of quantum physics.

What is the God particle?

The God particle is just a fancy name for a sub-atomic particle called the Higgs Boson. This particle is the last piece of mystery in the Standard Model, which is a model containing all the elementary particles and intending to explain all particle interaction in particle physics. Higgs was proposed by three teams of theorists in 1964: François Englert and Robert Brout, Gerald Guralnik, C. R. Hagen, and Tom Kibble (GHK), and Peter Higgs, whom the particle was named after. Higgs is known to be the last particle which holds a critical explanation of where the mass of all matter comes from.

What is mass and where is it from?

Mass is a measure of how much matter is contained in an object. We know mass exists because we feel the gravitation as our weight. Our weight changes depending on which planet we’re on, depending on its mass and radius. However, our mass never changes.

What exactly was discovered?

The particle that was discovered and announced yesterday by CERN is a Higgs-like particle at 5-sigma significance, which is the standard to claim a discovery in particle physics. This number translates to a 99.9999 percent confidence level that the observed event is not a statistical fluctuation. Higgs-likes means it has some of the properties that agree with the predicted properties of the Higgs bosons; however, there are other properties needed to be tested with more data. It is still a new particle, regardless, but whether it’s the Standard Model Higgs or not has yet to be confirmed. If it is the Standard Model Higgs then the Standard Model is complete. If not then we might need other models or theories to explain the whole thing in a coherent way. If this particle is really the Higgs Boson, it will give us an explanation of where mass comes from, in other words, our origin.

How does this benefit anyone?

Although there is no direct benefit that we can easily see in our everyday life, there are many benefits derived from the scientific innovations leading up to this research. One of the many great examples of this is the World Wide Web, which we use widely everyday and has become indispensable in our lives. It was originally invented at CERN as a tool to better and more easily communicate with each other within big collaborations, but it now is one of the most important components of the Internet, which we all greatly benefit from. There are many other great applications coming from the technological advancements of this scientific effort, such as medical imaging and particle therapy, which is the most effective way to treat various cancers. These techniques make use of the particle accelerator technology, computer simulation and so on, which are the results from such kind of fundamental science research.

The term "God Particle" came from the book "The God Particle / If the Universe is the Answer, What is the Question?," by Leon Lederman & Dick Teresi (first published in 1993 and reissued in 2006), which is in the bibliography of my free ebook on comparative mysticism.

In his 2006 Preface Dr. Lederman, a Nobel laureate in physics, wrote:
"Now as for the title, The God Particle, my coauthor, Dick Teresi, has agreed to accept the blame. I mentioned the phrase as a joke once in a speech, and he remembered it and used it as the working title of the book. The title ended up offending two groups: 1) those who believe in God and 2) those who do not. We were warmly received by those in the middle."
