New to this tour in physics? Start at THE BIG BANG.
“The Higgs Field is an invisible energy field that exists throughout the universe. The field is accompanied by a fundamental particle called the Higgs Boson, which it uses to continuously interact with other particles. As particles pass through the field they are endowed with the property of mass, much as an object passing through treacle (or molasses) will become slower.
Although apparent, mass is not generated by the Higgs field, as creation of matter or energy would conflict with the laws of conservation; mass is, however, transferred to particles from the field, which contains the relative mass in the form of energy. Once the field has endowed a formerly massless particle the particle slows down because it has become heavier.
If the Higgs field did not exist particles would not have the mass required to attract one another, and would simply float around freely at light-speed.
The process of endowing a particle with mass is known as the Higgs Effect.”
Remember that The Higgs Field started giving the Universe mass within the first million’th of a second.
This is the field that physicists searched for, since the sixties. It gave the Nobel price to Peter Higgs this summer.
