Let P T be the probability that a method predicts the existence of an edge given that the edge exists, and P F the probability of predicting the existence of an edge given that the edge does not exist.
PPV refers to the rate at which some intervention correctly predicts the existence of some factor, whereas negative predictive value refers to the rate at which some intervention correctly predicts the inexistence of some factor.
In addition to the Higgs boson, or bosons, electroweak theory also predicts the existence of an electrically neutral carrier for the weak force.
One bonus of supersymmetry is that it predicts the existence of more, yet undiscovered elementary particles, one of which might be the mysterious dark matter that binds galaxies together in the universe.
Woit does raise several technical concerns — well-studied by string theorists — with a principle known as supersymmetry, a component of superstring theory that predicts the existence of a new, and so-far undiscovered, set of subatomic particles.
Furthermore, Weinstein's theory predicts the existence of more than 150 new subatomic particles, most of them with exotic properties (such as electric charges that are greater than one, which is the maximum seen in nature at present).
By analogy with QED, quantum chromodynamics predicts the existence of force-carrier particles called gluons, which transmit the strong force between particles of matter that carry "colour," a form of strong "charge".
(In 2008 Kobayashi and Maskawa were awarded the Nobel Prize for Physics for their "discovery of the origin of the broken symmetry which predicts the existence of at least three families of quarks in nature").
The theory predicts the existence of a new particle, which also carries Prof Higgs' name.
It might make way for a rival idea which predicts the existence of a 'fifth force' of nature.
In particular, the model predicts the existence of four grain refinement transitions, three of which are observed experimentally.
