- Why is cold fusion considered bogus? - Physics Stack Exchange
Pons and Fleischmann originally reported in 1989 that their chemical cells had produced excess heat, neutrons, and tritium Their interpretation was that deuterium nuclei were fusing to produce 4He The branching ratios in this process are known: 50% n+3He, 50% p+3H, and 10^-6 4He+gamma

He4 emissions have been reproducibly detected many times, starting with Paneth and Peters, continuing with Pons Fleischmann, later McKubre, and most recently in Arata type cells While these He nuclei could be alphas emitted from heavy nuclei decaying, it is much more likely, given the concurrent heat production, that the alphas are emitted by
- Is the E-cat by Andrea Rossi et al. for real?
Unlike Pons Fleischmann cells, or variants like Arata's or SPAWAR, Rossi is claiming fusion of ordinary hydrogen in Nickel On the crazy-meter, Nickel-Hydrogen cold fusion is to Pons-Fleischmann cold fusion as Pons-Fleischmann fusion is to fire
- electromagnetism - Do primary first class constraints change the . . .
There is also a nice discussion and possibly a very detailed answer to the exact question posted above, in paper by Pons, as well as in Sundermeyer's book "Symmetries in Fundamental Physics" The bottom line is: isolated first class constraints (primary or secondary or tertiary ) do not , in general, generate gauge transformations
- Is there any reproducible tested evidence for Ni-H cold fusion?
$\begingroup$ Palladium Deuterium cold-fusion certainly exists, as tritium was detected by Pons Fleischmann at Utah, at Bhabha, at Texas A M by two independent groups (Wolf and Bocris) and also at Los Alamos (but the fellow was not allowed to publish) That settles the question of nuclear effects for good, and there is nothing you can say
- Why do whips hurt so much? - Physics Stack Exchange
The speed of the tip of the whip can exceed the speed of sound From Wiki: The crack a whip makes is produced when a section of the whip moves faster than the speed of sound creating a small sonic boom

Yes, the claims in the video are totally absurd from the viewpoint of science It's enough to listen for roughly 70 seconds to be sure that the narrator doesn't have the slightest clue about physics and the remaining 302 seconds make this fact even more self-evident

$\begingroup$ @Jonathan : good question The neutron doesn't even know what its end state should be At the quantum scale, things literally don't stay put
