I know almost nothing about physics. What I do know is hopelessly mixed up with what I don't know.

Full disclosure: Most of my questions go back to cold fusion in some way. You can find me on Vortex-L.

comment Does the pilot of a rocket ship experience an asymptotic approach to the speed of light?
@JohnRennie -- how does the following section in the Wikipedia article on FTL relate to my question and your answer? en.wikipedia.org/wiki/Faster-than-light#Proper_speeds Is it that the pilot does not perceive FTL, but when he does the calculation across different inertial frames, he gets a proper velocity that is faster than light?

comment Is there any reproducible tested evidence for Ni-H cold fusion?
"since the scientific evidence is that Pd-d cold fusion is bogus." -- You're mixing up current theoretical understanding with experimental evidence. Your challenge at this point is an empirical one. You must show why every experiment is invalid in some way. Theory is only distantly relevant at this point. As a practical matter, your most effective strategy will be to discredit everyone looking at this stuff as crackpots.

comment Can Rydberg states exist within the bulk of a metal?
@BenCrowell: As an assistance to anyone who might be confused on that point, I am adding a note to my profile to this effect. Feel free to point people to it.

comment Can Rydberg states exist within the bulk of a metal?
@BenCrowell: you're not outing anyone -- I freely acknowledge that this is related to cold fusion. All of my questions are related to cold fusion. But I think you're missing the interesting physics of it, outside of that context, which is what is relevant to this site. (Interesting, at least, to amateurs who are still learning about this stuff.)

comment Can Rydberg states exist within the bulk of a metal?
I was thinking of the donor site in the semiconductor case, which is interesting. About the delocalization of the electrons -- I believe this only holds for the most loosely bound electrons. Unless I am mistaken, a majority of the electrons are still quite localized around the lattice sites.

comment Can Rydberg states exist within the bulk of a metal?
No intentional connection to Holmlid's work -- my reference is primarily the series of experiments with rubidium atoms along the lines of the phys.org article. But your comments are helpful.

comment Can Rydberg states exist within the bulk of a metal?
@KevinDriscoll: Interesting thought. My off-the-cuff ideas -- (1) kinetic energy of the metal atoms is << eV, while the electronic structure requires energy on the order of eV to perturb. (2) Higher temperatures should increase rather than decrease the likelihood of perturbation.

comment Widom-Larsen Theory
@BenCrowell: anyone who has spent time reading through through the 1989-1990 papers as well as the later work would make a more cautious statement, even if they thought that cold fusion was mistaken.
