Galaxies powered by black holes

That is the inference in a story at www.dailygalaxy.com/my_weblog/2014/04/young-galaxies-powered-by-massive-… …. and opens with the statement, all matter of fact, 'quasars- are young galaxies powered by massive black holes, extremely bright, extremely distant, and highly red shifted …'

EU enthusiasts have their own take on this story – go to www.thunderbolts.info … but the rest of us need to persevere and keep the mind locked into what is being said. Quasars, it seems, have been used to map density variations in intergalactic gas at high red shifts, tracing the structures of the young universe. The Boryon Oscillation Spectroscopic Survey (part of the Sloan Digital Sky Survey) charts the history of the expansion of the universe in an attempt to understand dark energy (among other things). The building blocks leading up to the conclusion are a bit like Lego sections in the hands of a serious constructor – and how it is put together is really rather clever.
