11Linear particle accelerator — A linear particle accelerator (also called a linac) is an electrical device for the acceleration of subatomic particles. This sort of particle accelerator has many applications, from the generation of X rays in a hospital environment, to an… …
12subatomic particle — or elementary particle Any of various self contained units of matter or energy. Discovery of the electron in 1897 and of the atomic nucleus in 1911 established that the atom is actually a composite of a cloud of electrons surrounding a tiny but… …

15Virtual particle — In physics, a virtual particle is a particle that exists for a limited time and space, introducing uncertainty in their energy and momentum due to the Heisenberg Uncertainty Principle. (Indeed, because energy and momentum in quantum mechanics are …
16List of accelerators in particle physics — A list of particle accelerators used for particle physics experiments. Some early particle accelerators that more properly did nuclear physics, but existed prior to the separation of particle physics from that field, are also included. Although a …
17Large Hadron Collider-The World's Most Powerful Particle Accelerator — ▪ 2009 On Sept. 10, 2008, scientists of the European Organization for Nuclear Research ( CERN), Geneva, ran the first test operation of what had been described as the largest machine and the most ambitious scientific experiment ever built… …

19Event horizon — In general relativity, an event horizon is a boundary in spacetime, an area surrounding a black hole or a wormhole, inside which events cannot affect an outside observer. Light emitted from inside the horizon can never reach the observer, and… …
20quark — /kwawrk, kwahrk/, n. Physics. any of the hypothetical particles with spin 1/2, baryon number 1/3, and electric charge 1/3 or 2/3 that, together with their antiparticles, are believed to constitute all the elementary particles classed as baryons… …
