cosmic microwave background radiation

n.
Microwave radiation that penetrates space throughout the universe, postulated to be residual electromagnetic radiation originally emitted by warm matter in the universe approximately 400,000 years after the Big Bang. Also called cosmic background radiation, cosmic microwave background, microwave background.

This afterglow is called cosmic microwave background radiation.
The glow, called cosmic microwave background radiation, carried an imprint of large waves to the detectors on Earth.
The aim of Romalis' project, "A Test of CPT Symmetry Using a New [K-.sup.3] He Self-Compensating Magnetometer," is to perform a high-precision test of combined charge conjugation, parity inversion, and time reversal (CPT) invariance and local Lorentz invariance by comparing the Larmor precession frequencies of potassium (K) and helium 3 ([He.sup.3]) atoms in the same cell as a function of time, i.e., the daily rotation of the Earth about its axis and the movement of the Earth relative to the cosmic microwave background radiation. The experiment will improve the existing tests of these important fundamental symmetries of nature by a factor of 1000 and should provide tests of various theories of quantum gravity, such as string theory, which predict violations of CPT and Lorentz invariance.
of Energy's National Energy Research Scientific Computing Center (NERSC) at Lawrence Berkeley National Laboratory, along with software developed there, helped obtain the most detailed measurements yet of cosmic microwave background radiation. The results were recently released by the international BOOMERANG consortium, led by Andrew Lange of the California Institute of Technology and Paolo Bernardis of the University of Rome.
This is due in part to the scarcity of events that can accelerate particles to such enormous energies, and partly because these particles lose energy when they collide with the ever-present cosmic microwave background radiation.
Planck's result, reported in a paper published online May 10 at arXiv.org, is based on measurements of the cosmic microwave background radiation, ancient light that originated just 380,000 years after the Big Bang.
In 2001, Cramer wrote a science-based column for Analog Science Fiction and Fact magazine describing the likely sound of the Big Bang based on cosmic microwave background radiation observations taken from balloon experiments and satellites.
