Classical Physics:
A general term used to describe the physics based on principles developed before the rise of general relativity and quantum mechanics, essentially physics as it had existed up to the early years of the 20th Century. It includes the mechanics of Galileo and Newton, the electrodynamics of Maxwell, the thermodynamics of Boyle and Kelvin, and usually even the special relativity of Einstein.
Complementarity:
The idea in quantum theory that items can be separately analyzed as having several contradictory, and apparently mutually exclusive, properties. For example, the wave-particle duality of light, wherelight can either behave as a particle or as wave, but not simultaneously as both.
Copernican Principle:
The idea that there is nothing special about our position in the universe, a generalized version of Nicolaus Copernicus’ recognition that the Earth is actually just a planet circling the Sun, and not vice versa.
Cosmic Microwave Background Radiation:
Cosmic microwave background radiation (or CMB for short) is the “afterglow” of the Big Bang, a microwave radiation which still uniformly permeates all of space at a temperature of around -270°C (about 3° above absolute zero). It is considered to be the best evidence for the standard Big Bang model of theuniverse.
Cosmic Inflation:
The idea that, in the first split-second after the Big Bang, theuniverse underwent a fantastically fast (exponential) expansion driven by the vacuum of empty space. The theory was developed by Alan Guth in the early 1980s to explain certain problems and inconsistencies with the basic Big Bang theory, such as those related to the large-scale structure of the features of the universe, the “horizon problem”, the “flatness problem” and the “magnetic monopole problem”.
Cosmic Rays:
High speed, energetic particles (about 90% of which are protons) originating from space that impinge on Earth's atmosphere. Some are generated by our own Sun, some by supernovas, some by as yet unknown events in the farthest reaches of the visible universe. The term "ray" is a misnomer, as cosmic particles arrive individually, not in the form of a ray or beam of particles.
