That's before cold fusion.
This latest bit of math looks just as intriguing ~ too many people imagine you can pile up vast mountains of water and not have some real world quantum effects take place right before your eyes ~ like even bigger waves without benefit of overlaps!
Concerning scientific proof, math is the proof. Pictures can be faked easily by 6th graders these days. You find a grade school kid faking math, now you've got something eh!
This link shows how the officers of the Ramapo triangulated the wave height. Their report is, AFAIK, the first 100% credible and documented scientific observation of extremely large waves:
