In the beginning there was a void. Then a God Created Light, Earth and Stars
(not necessarily in that order)
The Laws of Physics are no different
They all have one thing in common, “A Trigger”
This is true in all religions from the Judeo/Christian to
the Muslims, to the Buddhists to the Hindus to
the Native Americans
The Beginning

Scientific Method
Scientific method is a body of techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge. To be termed scientific, a method of inquiry must be based on empirical and measurable evidence subject to specific principles of reasoning.
It must be repeatable and can always be disproven.
![Page 10: Bosons and Photons and Gluons, Oh My](https://reader031.vdocuments.net/reader031/viewer/2022021617/620ac6b5e98b9d4aa1595177/html5/thumbnails/10.jpg)
Hypothesis - Theory - Law
HYPOTHESIS - an educated guess, based on observation.
THEORY - A scientific theory summarizes a hypothesis or group of hypotheses that have been supported with repeated testing.
One definition of a theory is to say it's an accepted hypothesis.
LAW - a body of observations. At the time it is made, no exceptions have been found to a law.

What Are FieldsFields are a mathematical representation of how forces act on particles. There are 3 basic field in The standard theory, four if Higgs boson is real. The fields require two things, a mediator and something to mediate. The exchange of the mediator particle creates the force field. The fields are:
Field Mediator Mediatee Type FieldElectromagnetic Photon Electron VectorWeak W & Z bosons Radioactive Matter VectorStrong Gluons Quarks VectorGravitation Higgs Boson Gravitons (hypothetical) Scalar
Higgs bosons, excitations of one component of the Higgs
field, which gives mass to fundamental particles

MediatorsThe Standard Model explains forces as resulting from matter particles exchanging other particles, known as force mediating particles. When a force-mediating particle is exchanged, at a macroscopic level the effect is equivalent to a force influencing both of them, and the particle is therefore said to have mediated that force.

Higgs
Charlie Rose With Brian Greene and Michael Tuts
The Higgs boson is named for Peter Higgs because he was the only one to explicitly predict the massive particle and identify some of its theoretical properties
In 1964 three teams proposed related but different approaches to explain how mass could arise in local gauge theories. 1.Robert Brout and François Englert,[1][2]
2.Peter Higgs,[3] and Gerald Guralnik,3.C. Richard Hagen, and Tom Kibble,[4][5]

Higgs Past Prediction: circa 2008
A pair of otherwise distinguished physicists have suggested that the hypothesized Higgs boson, which physicists hope to produce with the collider, might be so abhorrent to nature that its creation would ripple backward through time and stop the collider before it could make one, like a time traveler who goes back in time to kill his grandfather.
Remember when the LHC was having so many problems?
They Were wr wr Wrong!

“Ever since physicists announced their discovery of the Higgs boson particle in Switzerland on July 4, I keep being told that its existence fundamentally alters our knowledge of the universe. I have no idea who this "our" refers to. My knowledge of the universe is that if I write stupid jokes, the universe gives me a really nice house and great meals. I do not believe mankind will ever develop a formula to explain this.”
Joe Klein Time Magazine
So What?

Well…First and foremost, is the scientific importance of this discovery.
Is this quest worth a few billion dollars in these difficult financial times and our immediate future?
The poplar answer is probably no. But what about 20 or 50 or 100 years down the road?
History has taught us that the fundamental research of today is the technology of tomorrow.
Could anyone have foreseen how quantum mechanics would become the bedrock of our current technology or how important Einstein's theory of general relativity would be?
