DARK MATTER. “Its particle nature is still the subject of exciting speculations since no evidence has been found, neither in direct production at the LHC, nor in direct detection at underground experiments, over an amazingly large interval of masses and physical properties.” (LHC = The Large Hadron Collider). https://link.springer.com/content/pdf/10.1007/s10686-021-09708-w.pdf View in LinkedIn

“BUBBLE NEBULA. Also known as NGC 7635, the Bubble Nebula was created by a petulant star, around 45 times the mass of our Sun, throwing out its gas, or stellar wind. The gas is travelling at around 6.5 million kilometres per hour, and as the resulting cloud expands out, it slams into the surrounding interstellar medium – this is the gas which fills the space between the stars – creating a shock wave.” https://lnkd.in/gu7xi9dj View in LinkedIn

BEYOND. “I don’t know what I may seem to the world, but as to myself, I seem to have been only like a boy playing on the sea shore and diverting myself in now and then finding a smoother pebble or prettier shell than ordinary, while the great ocean of truth lay all undiscovered before me.” (Isaac Newton). https://lnkd.in/dCkkSu3Y View in LinkedIn

UNEXPLAINED. “Nuclear Antimatter seems to be extremely rare in today’s visible Universe: most of the antiparticles produced after the post-inflation reheating seems to have disappeared during the baryonic annihilation phase, although convincing mechanisms for this asymmetry have not been put forward.” https://link.springer.com/content/pdf/10.1007/s10686-021-09708-w.pdf View in LinkedIn

PARADIGM THREATS. “The study of high-energy antiparticles in the cosmic radiation may have groundbreaking consequences for cosmology, astrophysics, and particle physics.” https://link.springer.com/content/pdf/10.1007/s10686-021-09708-w.pdf View in LinkedIn

HOLDING THE KEYS. “CRs are a unique kind of messenger connecting fundamental physics, cosmology, and astrophysics. Notable examples of open issues which can be addressed by the study of CR are the still unexplained asymmetry between matter and antimatter in our Universe and the puzzling nature of Dark Matter, six times more abundant than matter.” (CR = cosmic ray). https://link.springer.com/content/pdf/10.1007/s10686-021-09708-w.pdf View in LinkedIn

SAMPLE OF THE COSMOS. “These particles are thus a genuine sample of solar, galactic, and extragalactic matter that includes all known nuclei and their long-lived isotopes, as well as electrons and antiparticles. This makes the CR radiation a unique messenger to probe high-energy phenomena. The CR energy spectrum extends several orders of magnitude from ~10(6) eV to about ~10(21) eV.” (CR = cosmic ray). https://link.springer.com/content/pdf/10.1007/s10686-021-09708-w.pdf View in LinkedIn

ORIGIN OF COSMIC RAYS. “The leading paradigm is that the bulk of CRs are generated in Galactic processes such as supernova explosions or stellar winds, although extragalactic sources and secondary production by primary CRs with the Interstellar Medium (ISM) may contribute as well to the observed flux.” (CR = cosmic ray). https://link.springer.com/content/pdf/10.1007/s10686-021-09708-w.pdf View in LinkedIn

SCRAMBLED INFORMATION. “The origin of CRs remains a century-old puzzle also considering the fact that, before reaching Earth, their directions are randomized by the interstellar magnetic fields.” (CR = cosmic ray). https://link.springer.com/content/pdf/10.1007/s10686-021-09708-w.pdf View in LinkedIn
