What you have found is merely an hypothesis. For every successful hypothesis that becomes a bonafide theory, there are thousands that don't.

What you have found here is very common. That is, it's a daily occurrence that a scientist (or a few scientists working together) produces a new study that purports to debunk some widely-accepted, contemporary theory. Usually, however, these studies are characterized by some misstep not detected by its originators. Scientific theories don't sink that easily.

Don't invest too much into other people's 'revolutionary' hypotheses until those hypotheses have been tested, confirmed, and otherwise scrutinized by a significant portion of the scientific community.

If I were properly motivated, I could find you references by PhDs from major universities debunking just about every modern scientific theory out there. With the internet, these fringe ideas are easier than ever to spot, but they should not be equated to 'theories' just yet.
