Big Bang’s Afterglow Fails an Intergalactic Shadow Test


A paper that is going to be published in ApJ this month has found a problem with an expected observation support for the Big Bang:

“The apparent absence of shadows where shadows were expected to be is raising new questions about the faint glow of microwave radiation once hailed as proof that the universe was created by a ‘Big Bang.'”

Very curious. There may be other ways to explain this observation, but it’s a little disconcerting to read none the less. The Big Bang is very well supported theory and especially so since the COBE experiments in the late nineties…
