Firstly, it takes several experiments to prove a theory. It ALSO take several experiments to disprove a theory. Your link only leads to a summary of one experiment. That is not enough to prove or disprove anything.
Secondly, the link leads to a summary, not an actual journal article. And the summary is filled with plenty of bias. Have you gone through university? Because if I used a link to a biased summary on my paper, I would fail for sure. It's just not up to university standards.
