HIGH ENERGY RAYS. “The longstanding simple picture of a featureless and universal power-law energy spectrum of CRs might have been finally overcome. A remarkable change of spectral indices has been established for several CR energy spectra at a kinetic energy of about 300 GeV.” (CR = cosmic ray). https://link.springer.com/content/pdf/10.1007/s10686-021-09708-w.pdf View in LinkedIn

PROMISING DATA. “CR protons and nuclei. Accurate, recent measurements of the most abundant CR species, such as protons and helium have recently revealed new and unexpected features in their energy spectra, that may shed new light on the acceleration and propagation mechanisms of CRs in the Galaxy.” (CR = cosmic ray). https://link.springer.com/content/pdf/10.1007/s10686-021-09708-w.pdf View in LinkedIn

TANTALIZING CLUE. “It is now generally accepted that the positron and electron spectra can be jointly understood only assuming the existence of as yet unknown sources of high-energy positrons and electrons in the Galaxy. The positron excess has caused a huge interest.” https://link.springer.com/content/pdf/10.1007/s10686-021-09708-w.pdf View in LinkedIn

ANTIMATTER SEARCH. “All the experiments observed a very significant and unexpected excess in the positron flux above 10 GeV: the positron energy spectrum is significantly different to the electron one and it is not compatible with the expected astrophysical background.” https://link.springer.com/content/pdf/10.1007/s10686-021-09708-w.pdf View in LinkedIn

“Two galaxies colliding into each other sounds like it should be hazardous, if not fatal, to the objects involved. In reality, it is the main way these stellar collectives grow and evolve. When they crash together, or even just pass close by, the resulting chaos stirs up the gas within them, creating knots of material which go on to form stellar nurseries.” https://lnkd.in/gu7xi9dj View in LinkedIn

CRY IN THE DARK. “Lee Smolin claims that “[p]hysics should be more than a set of formulae that predict what we will observe in an experiment; it should give a picture of what reality is .... It cannot be that reality depends on our experience.” (Smolin 2006) https://lnkd.in/eAxeE3iE View in LinkedIn

UNKNOWN MODES OF BEING (WW). “There was a hint of fear, not for our lives, but of a vast unknown which pressed in upon us. A fleeting feeling of disappointment -- that after all those dreams and questions this was only a mountain top -- gave way to the suspicion that maybe there was something more, something beyond the three-dimensional form of the moment. If only it could be perceived.” (Tom Hornbeam, 1963 upon summiting Everest, page 1). https://lnkd.in/exjbzyHG View in LinkedIn

CONSEQUENCES. “The probability of this oscillation occurring is small, but it holds the key to leptonic CP violation: if CP symmetry is conserved, the oscillation probability for muon-to-electron neutrino conversion would be the same as that for muon-to-electron antineutrino conversion.” (CP = charge-conjugation parity-reversal). https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn

NEW FINDING. “Since their discovery, neutrino oscillations have been analysed in several experiments, but only in the past few years have tiny oscillations from muon neutrinos to electron neutrinos been observed.” https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn
