Sep 22, 2011 · In the past, after Fleischmann and Pons announced their cold fusion results, in perfectly good faith, they were proven wrong by subsequent experiments. What are the experimental realities …
Is there any reproducible tested evidence for Ni-H cold fusion?
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 …

What is wrong with this derivation of Gravitational Pressure?
Jan 7, 2026 · My question is : Since this derivation gives the pressure to be infinite at r = 0 r = 0, it is clearly wrong, but I cannot find the flaw here because as far as I know, I just replicated the Proof for …
Why do I get negative entropy? - Physics Stack Exchange
Aug 29, 2025 · Yes, but I was trying to find the absolute entropy (like the one in the Boltzmann definition), not the Δ. So I thought to do this. Once we know that ΔS=Cln (T2/T1) we can split …
Is the E-cat by Andrea Rossi et al. for real?
Oct 11, 2014 · Rossi's device 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 …
optics - Virtual vs Real image - Physics Stack Exchange
I'm doing magnification and lens in class currently, and I really don't get why virtual and real images are called what they are. A virtual image occurs the object is less than the focal length of...
Why does water reflect light? - Physics Stack Exchange
Oct 4, 2015 · Why does water reflect light? What is actually happening when light is reflected by water? We know why metals reflect light; water, however, is not metal, but it still reflects light and we can see...
