I have a Physics degree, but no special understanding of cosmology. I hope this isn't an anti-science thread. What makes you think that these were "once thought to be inconsistent with the Big Bang Theory". According to whom?
In science when you get new data that contradicts an existing theory, you go back to work... sometimes the new data suggests a minor change to the theory, occasionally it means the theory needs to be completely reworked. That is one of the unique strengths of the hard sciences... it is all about evidence. You go with the evidence whether it supports your ideas or not.
