[24] [46] Examples include computer keyboards and electric guitars. [47] The goal of such redesigns is to employ appropriate materials (such as polished brass, iron, wood, and leather) with design elements and craftsmanship consistent with the Victorian era, [ 21 ] [ 48 ] rejecting the aesthetic of industrial design .

There is background radiation observed across all wavelength regimes, peaking in microwave, but also notable in infrared and X-ray regimes. Fluctuations in cosmic background radiation across regimes create parameters for the amount of baryonic matter in the universe. [5] See cosmic infrared background and X-ray background.
The cosmic microwave background was first predicted in 1948 by Ralph Alpher and Robert Herman, in a correction [16] they prepared for a paper by Alpher's PhD advisor George Gamow. [17] Alpher and Herman were able to estimate the temperature of the cosmic microwave background to be 5 K. [18]
In physical cosmology, the uncapitalized term cosmic signifies a subject with a relationship to the universe, such as 'cosmic time' (time since the Big Bang), 'cosmic rays' (high energy particles or radiation detected from space), and 'cosmic microwave background' (microwave radiation detectable from all directions in space).
CMB spectral distortions are tiny departures of the average cosmic microwave background (CMB) frequency spectrum from the predictions given by a perfect black body.They can be produced by a number of standard and non-standard processes occurring at the early stages of cosmic history, and therefore allow us to probe the standard picture of cosmology.
Cosmic background may refer to: Cosmic microwave background radiation (CMB) Cosmic neutrino background (CνB) Cosmic gravitational wave background (GWB)
The Hubble eXtreme Deep Field (XDF) was completed in September 2012 and shows the farthest galaxies ever photographed at that time. Except for the few stars in the foreground (which are bright and easily recognizable because only they have diffraction spikes), every speck of light in the photo is an individual galaxy, some of them as old as 13.2 billion years; the observable universe is ...
