From experiment to theory: an evidence for new physics far away from standard models, useful mainly in astrophysics.

Since 50 years there is a mystery about the origin of solar corona heating. Since 30 years there is a mystery about the nature of Hard Gamma Ralv Bursts that appear to be uniformly distributed on the shy. The origin of stellar/solar flares, coronal mass ejection, wind acceleration and cosmic ray production seems also not to be very well understood. We propose an apparently speculative new concept of "fundamental momentum" (fm,tachyon), and its absorption (fma) on particles as the possible common solution to all these mysteries. A fm with a pseudomass M =418 keV/c(2) would be the sister of the electron, born in 1897, with mass m = 511 keV/c(2). Single fma onto one electron at rest in metallic detector housing, or in solar plasma, would give it a K.E. of 170 keV, a "temperature" of 1973 MK. in the detector. it would mistakenly be attributed to a gamma ray of the same energy. Single fma onto protons at rest would give them a velocity of 133 km/s, a K.E. of 93 keV, a "temperature" of 1.08 MK. Single fma onto a nucleus at rest of atomic mass A would give it a velocity of 133/A km/s. The hn signal would be embarrassingly superluminal, supported by some HGRB observations, when these are correctly interpreted. Once the solar origin is ascertained, the fm field could propagate across-a solar diameter in 7 s by an electronic fm wave. It could be a possible candidate for Dark Matter by its energy content emanating fi-om every star and be at the basis of the Hot Universe. The Kozyrev effect-could also be explained and the Sun would be an anticipatory system.
