Early last week, exciting news was released that scientists are both Fermilab and CERN were getting closer and closer to pinning down the location of the so-called "god particle," otherwise known as Higgs Boson. Then, this past Wednesday as America celebrate the 4th of July, nerds around the world had their own fireworks as they announced that Higgs Boson had indeed been found. With a 5 sigma signal, meaning that there is less than a one in a million chance that the findings are a fluke, scientists the world over could deem the particle found. Declared the "god particle" because of its relation to the "Big Bang," or the moment of the creation of our universe, this particle has been deemed crucial by physicists because they hope it can answer the previously unanswerable about the actual existence of dark matter, the possibility of additional dimensions or universes, and hopefully to finally confirm the unified field theory that finally brings beautiful symmetry between Einstein's theory of gravity and quantum physics involving subatomic particles. According to Peter Higgs, half of the namesake of the discovered particle:
Although this probably swept beneath the general public's rug of consciousness, it's kind of a big eff'n deal. It is WAY above my pay grade to truly describe what the Higgs Boson does (here is a good, and fairly simply explained, primer from the Atlantic) and why it is important, but here is the basic gist:"I had no expectation that I would still be alive when it happened," he said of the speed with which they found evidence.
"For physics, in one way, it is the end of an era in that it completes the Standard Model," he said of the basic theory physicists currently use to describe what they understand so far of a cosmos built from 12 fundamental particles and four forces.
Scientists struggling to explain the theory have likened Higgs particles to a throng of paparazzi photographers; the greater the "celebrity" of a passing particle, the more the Higgs bosons get in its way and slow it down, imparting it mass; but a particle such as a photon of light is of no interest to the paparazzi and passes through easily - a photon has no mass.So, essentially and more complexly, the exchanges between various fields and bosons, a general class of subatomic particle of which Higgs is a type, is called the Higgs mechanism, which is still not fully understood, and it is through these exchanges that particles gain mass (Thanks Atlantic Monthly!).
Phew. You still with me? Because at this point I'm just continuing to write to help myself fully understand. But that's all folks
UPDATE: In a closer reading of the material released, it is not entirely a settled matter that it is exactly the Higgs Boson that has been found (although many believe it is so). According to Reuters:
What scientists do not yet know from the latest findings is whether the particle they have discovered is the Higgs boson as exactly described by the Standard Model. It could be a variant of the Higgs idea or an entirely new subatomic particle that could force a rethink on the fundamental structure of matter.
The last two possibilities are, in scientific terms, even more exciting.Sooo, definitely very exciting nonetheless.
