The author has been quoted saying: "I'm neither a mathematician nor a physicist. More accurately, I'm a gardener and home handyman who does science in his spare time." [2]
This is abundently clear throughout the article. One of my favorite parts is when he is arguing against a few different PhD's, and uses his own YouTube video as a reference to defend his argument (which appears to be the only reference in the entire article).
I'd avoid reading unless looking for an entertainment piece.
