Dark-energy particle spotted?

Reported 'chameleon' particle would change its mass to match its environs.

Cosmologists don't usually take their lead from the animal kingdom. But a model that postulates the existence of a 'chameleon' particle — which would change its mass depending on its surroundings — is gaining attention.

  • If gravitation quantized, if supersymmetric partners appeared, if protons decayed, if the Higgs boson appeared, if dark matter were detected in labware, if string or M-theory predicted anything testable, fine. Things are not fine. Now a particle class will "change its mass depending on its surroundings." Quantum gravitation theories require supplementing Einstein-Hilbert action with an odd-parity Chern-Simons term only active in the massed sector, arxiv:0811.0181 . Cultured quartz in enantiomorphic space groups P3(1)21 and P3(2)21 offers opposite parity atomic mass distributions, 0.01256 nm^3/atom. Glycine gamma-polymorph in enantiomorphic space groups P3(1) and P3(2) has even more tightly packed atoms, 0.007869 nm^3/atom. Run a parity Eotvos experiment and discover whether physics needs a subtle founding postulate rewrite to quantize gravitation - Equivalence Princple falsification. It is no less incredible and it is beyond argument after being observed and reproduced, either way. Theorists boast promiscuity while empiricists pay child support.

  • The "chameleon" particle? Hahaha! All things to all quantum physicists ... lol. Gimme a break! All that "exists" are spherical waves in space masquerading as particles. It's that simple. See: "A Beautiful Theory of Everything" (www.abookofverse.blogspot.com)

  • Would you have to put a "mirror" back far enough in time to create these photons?

  • It is also possible that particles in high energy domains have more mass or acquire mass as it emerges out from such domains,due to some energy `pressure` `compressing` the mass as the particle is in the high energy domains-this could be due to effects attributed to signal interactions which cause the frequency associated with the particle mass to be attenuated on account of the energy pressures in the domain,to start with.As the particle emerges out from those high energy domain environs,the mass signal frequencies are enhanced since the `compression` from the energy pressures are no longer there,and the particle appears to have more mass. A distant observer would measure the event as an expansion in space,and accelerated expansion,since the redshift effects are analogous,since the particle slows down as its mass is enhanced.If one were to assume that the particle has not changed its mass as it exits the high energy domain,then one would observe it as an event of accelerated expansion from the redshifted signals proceeding from the particle. The idea has its relevance in explaining the puzzle of missing mass in the universe too,since a part of the mass is hidden in the particle,potentially ,and is not apparent ,when it exists in an high energy domain context,and becomes apparent only as it exits or comes out of the domain precincts,to lower energy domain context.
