There are many names and definitions given for the Higgs Field.
It is an all-pervasive field throughout every region of the universe, or the background on which the Higgs Boson interacts with other particles, which endows them with mass.
"The Higgs Field, is the space that the Elders speak of called 'spirit space;' the space between the lightening and thunder, the space before the sun comes up and the dark, the space between energy waves and solid matter."
- Dr. Leory Little Bear
In a quantum world constantly in flux, this is a place of transformation, where you never know, nor can know, precisely what will happen next. Simultaneously, quantum mechanics is the most successful physical theory to date, and can precisely predict the probabilities of outcomes of quantum experiments.
