Perhaps this topic will lead to a beneficial discussion.

Please look at this most fundamental quantum mechanical equation, considered "empirical" by Werner Heisenberg, but generally attributed to Louis deBroglie:

Lambda (that is wavelength, or RMS uncertaintly in position) = h/p, where p is classical Newtonian momentum, that is the product of mass and velocity. h is Planck's constant, known to be highly invariant, although sometimes given a few slightly different values depending on how it is derived.

Often somewhat misstated is the notion that one cannot specify an electron's position and its velocity simultaneously. More correctly it directly falls out of lambda = h/p, that is one cannot constrain MOMENTUM toward smaller values without simultaneously increasing lambda, that is the positional uncertainly of an electron. [The equation and the uncertainly relationship hold for larger and more massive objects, but the tiny mass of the electron make it particularly evident for that easily accessible particle.]

In all this is the assumption that an electron has a constant mass. And surely the Co-Data value for the electron is specified very precisely, even when it is locked positionally in a Penning trap. However, what happens to the deBroglie equation above if an electron is squeezed down to a quite fixed position AND it is constrained to a near zero velocity? If lambda, or positional uncertainty is to decrease because the electron is in fact being restrained, and if the velocity is nearing zero, it leaves only one variable to retain the relationship as described by the equation... that would be mass. Since the MEAN mass of the electron is precisely known, there may be only the possibility that the mass becomes time variant about that mean. Possibly related to this, an examination of "heavy electron" theory, will show that generally mass variation for electrons or "effective electrons" is vectorial, that is an increased effective mass in one direction is accompanied by decreases in at least one of the other spatial dimensions. I should note that the "deBroglie equation" has more complex variants that specify the variables with subscripts of x, y and z. Further there are relativistic versions. The general idea holds nevertheless.

One real world manifestation of the above discussion is the oft seen presence of oxides (and other electron deficient elements) in various situations involving unusual electron behavior. Such oxides are seen in high temperature superconductors, in low voltage work function electron emitters, such as oxides on electron gun filaments, AND very frequently in the literature of CF / LENR, for example calcium oxide and other oxides as critical components in the alloying of LENR devices. Why oxides? Is electron position and mass variation involved?

Does Planck length, mass and time, or quantum mechanics generally allow charge, position and mass components of an electron and/or proton to be dissociated sufficiently to tunnel one way [perhaps even around physics conventions] or another toward the empirically observed CF / LENR reactions? Can such interpretations be useful in selecting candidate materials and structures to facilitate high COP CF / LENR outputs? [Please also note that Planck mass is by far the largest dimensional quantum in our world, being in the microgram realm.]

It is not in my expertise to fully interpret any of this, but I do see something of interest in the "deBroglie equation", and I notice a distinct lack of mention of it in modern Physics discussions. The Nobel committee granted DeBroglie the Prize, but the Physics Community of the day apparently regarded him with some suspicion. Today this is essentially the same Physics Community undergoing a bit of a crisis with its currently criticized poor connection between grand theories and rather sparse and sometimes contradictory evidence.

Thanks for your attention! Perhaps we can evolve a useful theory as a group. It certainly seems important enough....
