This video reminded me of Voynich "I'VE SOLVED IT!" manuscript, cases so much

It must be noted though, that this video is about mathematics and physics. Hard sciences. Parts of solutions that rely on things like art history are inherently interpretative and somewhat subjective. They must be assessed by different means than repeatability.

That said, any solution of the text should be repeatable to a large degree. Otherwise it's just creative writing.
