Home Dictionary Name: high energy physicsHigh energy physics
the branch of particle physics which studies collisions of particles accelerated to such high energy that new fundamental particles are generated in the process The creation of new particles of very high energy is required to permit the study of the most fundamental relations between forms of matter so as to understand the fundamental nature of matter The high energies also reproduce the high temperature conditions at the earliest phase of the big bang allowing generation of some data relevant to understanding the nature and evolution of the universe...
Particle physics
That branch of physics which investigates the nature of matter and in particular the properties and behavior of the elementary particles fundamental particles of which matter is composed Included in this field is the more specialized branch of high energy physics...
big bang theory
The theory that the known universe originated in an explosive event the big bang in which all of the matter and energy of the universe was contained in a single point and began to rapidly expand and evolve starting as high energy particles and radiation and as it cooled over time evolving into ordinary subatomic particles atoms and then stars and galaxies According to this theory the four dimensional space time continuum which we perceive as our universe continues to expand to the present time but it is unknown whether the expansion will continue indefinitely or eventually stop or even reverse possibly leading to a contraction to a single point sometimes referred to as the ldquobig crunchrdquo The competing ldquoSteady state Theoryrdquo gradually lost favor in the 1980s and 1990s See also big bang...
X-ray
X-ray, a radiogram made by exposing photographic film to X-rays; used in medical diagnosis.X-ray, are special pictures of the inside of your body. A doctor will decide when you need an x-ray and what body part needs to be x-rayed. An x-ray machine, not a camera, is used to take these pictures, when the picture comes out it won't like the ones in your photo album, but doctors have learnt how to look at these pictures. Doctors can see broken bones, lung infections, and more.(1)(a) Relatively high-energy photon having a wavelength in the approximate range from 0.01 to 10 nanometers.(b) A stream of such photons, used for their penetrating power in radiography, radiology, radiotherapy, and scientific research. Often used in the plural. Also called reontgen ray.(2) A photograph taken with x-rays.Means electromagnetic radiation of short wave-length produced when high-speed electrons strike a solid target....
