The Cosmic Spectrum
The Cosmic Spectrum encompasses the colour of the universe throughout its existence, spinning in one continuous cycle. It charts a history of starlight, from the primordial era, through the Dark Ages and the appearance of the first stars, to the current Stelliferous Era and into the Far Future. It uses the 2dF Galaxy Redshift Survey and speculative data from leading scientists to establish the average colour of each era. The 2dF Redshift Survey measures the light from a large volume of the universe, more than 200,000 galaxies. Scientists Karl Glazebrook and Ivan Baldry analysis this data in order to determine the average colour of the universe today as it would be perceived by the human eye – a colour they coined ‘Cosmic Latte’.
