The Higgs Boson


THE HIGGS BOSON

Physics is as exciting as ever. The latest exciting event is the discovery of the Higgs Boson.   It was discovered on the 4th of July but was confirmed by peer review recently. Well, so what’s so special about this “God Particle”?

            First of all, the “God Particle” is a very misleading name. It has nothing to do with religion or creation and only served as a catchy name to sell a book. The Higgs Boson is simply the missing final piece of the puzzle that is the Standard Model. The Standard Model is literally a theory of everything. This theory describes the results of a particle collision or what keeps the sun burning or what the Earth is made of.  The Standard Model predicted most of physics, and each time a new particle was discovered, the physics community wasn’t surprised, as the Standard Model had already predicted the possible existence of such a particle. The only particle that hadn’t been discovered until now that was predicted by the Standard Model is the Higgs Boson. Now since the Standard Model accurately predicts electrons, protons, particle collisions and most of physics, we can assume it is accurate about the Higgs Boson, so in reality, proving the Higgs Boson exists is just “Scientific Fact Checking.”

            But what is the point of the Higgs Boson, what does it do? Nothing. The Higgs Boson does nothing. So why do we care? Because it’s an indicator that the Higgs Field exists. The Higgs Field is what we care about, as it is the Higgs Field that helps with the Weak Nuclear Force and gives mass to all matter. But what is the Higgs Field? Well first we have to figure out what a field is. A field is just a way to spawn particles. Think of the field as a line or plane with squares randomly placed. The more squares there are in one place, the more concentration there is on that place. So if you have the electron field, then where there is concentration you find electrons, where there is no concentration, there are no electrons. What makes the Higgs Field so different from all the different particle fields is the fact that it is super concentrated at every point. This super concentration is the mass of the universe. Sometimes, after a particle collision, a Higgs Boson may appear, as a leftover from the Higgs Field. The Higgs Boson is the proof of the Higgs Field.

            The Higgs Field provides everything in this universe its mass. But what is mass? That’s a very difficult question. So let us ask, what is something without mass. A massless particle, like a photon (a particle of light) travels at the speed of light, about 186,000 miles per second. In reality, the speed should be called the speed of massless particles, but light was the first massless particle observed so it remains the speed of light. Massless particles can only travel at the speed of light, but on the other hand anything with mass, like you and me, cannot travel at the speed of light. However, objects with mass can travel at any speed and have the luxury of staying still.  On a different note, massless particles can bounce off of other particles. And since a concentration of the super-concentrated Higgs Field is a particle, a massless particle could bounce off of the concentration. Since it is constantly concentrated, the particle could keep on bouncing and bouncing at the speed of light, but would appear to remain still. And this imparts mass to the particle. Congratulations Higgs Field! So everything, even you, are just high-speed particles constantly bouncing and gaining mass. The Higgs Field also participates in Weak Nuclear force (one of the four fundamental forces along with the Strong force, electromagnetic force, and gravity) and powers stars, causes nuclear decay enabling carbon dating and can cause nuclear explosions.

            The confirmation of the Higgs Boson is very important as it adds another puzzle piece to the Standard Model and may lead to more discoveries. Its most important contribution is its explanation of how mass is generated in the universe.
