Science can be unpredictable at times. I find it fascinating how small findings can have a dramatic impact.
Researchers thought they had found evidence of cosmic inflation - the idea that the universe grew rapidly in a tiny fraction of time just after the Big Bang. But it looks like they may have been misled by the dust in our own galaxy.
Another group of researchers are looking for the same evidence, and the two teams hope to work together to get to the bottom of it all.
