So stipulated. Consider the vacuum is isotropic in the massless
sector (photons) but has anisiotrpic structure in the massed sector (a
chiral pseudoscalar vacuum background comes to mind). All EM
observations will be blind to massed sector vacuum anisotropy.
Achiral and racemic massed sector observations will be blind to massed

There's an equally obvious problem with this argument -- its
incompleteness.
The "charge" of a particle is NOT its electric charge; but its total
gauge charge; i.e. that which is involved in Wong's equation. You
forgot, there's more than one force involved; and for gauge fields,
the electric charge now becomes a vector-valued quantity with one

There are some groups concerned with reactive scattering of three to five
atom systems. These systems can be investigated with full quantitative
quantum mechanical treatments of all relevant physical effects of both the
electronic structure and the reactive scattering itself.
Some pointers on recent work in this direction:

In what form?
I find this terminology very confusing.
Traditionally, dark energy refers to the (unknown) cause of the force
opposing gravitational attraction between matter in the universe at
large, and modelled as a re-introduction of Einstein's cosmpogical
constant.
What do you mean?
And what is v?

Just keep in mind. This model has 3 phases. Bodies at phase1 is
different from bodies at phase3. The law of momentum conservation
works, but it gives different result for bodies with different mass.
This is the comment from other forum.

Hmmm. You might try using the Newtonian equivalent of the

Paper [1] shows a similar magnitude of quantum coherence in conducting
polymers.
The work mentioned in [2] shows that an individual photon can excite
up to three electrons at once within quantum dots, and there is also
both previous and ongoing research on combining quantum dots with
polymers, e.g., just google the phrase "quantum dots polymers".

==========Moderator's note =============================
The statement quoted, I made before, has been a bit brief perhaps.
You are right, the valence quarks do not contribute much mass to
the proton. The point I wanted to make was that the hadrons consisting
of light valence quarks get their mass from the strong interaction, not

Here is a suggestion:
Search for: "How can the Planck length be claimed to be the smallest
length?". See pages 2 & 3, (posts # 17 thru # 42). These "Physics
Forums" posts show black hole and electron relationships. The
gravitational constant and the Planck constant are shown to have a
precise relationship. Also see "References" under Wikipedia article:
