The Big Bang theory has not been disproven. Get that idea out of your mind as fast as possible. Instead, a team of scientists have, this week, produced a paper which disproves their previous findings that suggest they'd found the first "direct evidence" that the Big Bang had happened in the way it's widely accepted to have happened. Instead of knowing when - 10 or so seconds after the Big Bang happened - the universe ballooned and expanded at a super-fast rate, we're back to where we were before the BICEP2 team announced their findings this past March. That's all.
