Why is it that Quasars don't red-shift? Any ideas or speculations? http://www.physorg.com/news190027752.html Surely all the measurements across all these quasars can't all be wrong. Is it possible that the Big Bang theory is wrong? Is it possible that the universe is not expanding? If so, then what are the alternatives? What other kinds of related measurements can be taken, which would shed further light on what's going on here?
