“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

THE NUT. “CP violation is one of the key ingredients needed to explain why there is a small excess of matter over antimatter in the Universe.” (CP = charge-conjugation parity-reversal). https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn

DARK MATTER SEARCHES. “In recent years, this field has witnessed significant advancements on both experimental and theoretical sides, stimulated by new-generation space-borne experiments such as PAMELA, the Fermi-LAT telescope, and the Alpha Magnetic Spectrometer AMS-02.” https://link.springer.com/content/pdf/10.1007/s10686-021-09708-w.pdf View in LinkedIn

THE PUZZLER. “Why is CP symmetry broken, and what are its consequences? This puzzling question lies at the core of our understanding of the laws of nature and the evolution of the Universe.” (CP = charge-conjugation parity-reversal). https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn

THE KEY. “The most promising channels for indirect DM searches are those involving antimatter in the final state, e.g. elementary antiparticles such as e+, anti-p or anti-nuclei such as anti-D, anti-3He.” (DM = dark matter). https://link.springer.com/content/pdf/10.1007/s10686-021-09708-w.pdf View in LinkedIn

THEORY. “Particle–antiparticle mirror symmetry is also known as charge-conjugation parity-reversal (CP) symmetry; it combines the charge symmetry between particles and their antiparticles with parity (the idea that physical laws should not change in an antimatter mirror world).” https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn

THEORETICAL SUPPORT. “Dark matter In spite of the lack of evidence for Beyond-Standard-Model (BSM) particles from experiments at the Large Hadron Collider (LHC), TeV-scale models of DM particles are nicely supported by cosmological constraints.” https://link.springer.com/content/pdf/10.1007/s10686-021-09708-w.pdf View in LinkedIn

RULE BREAKERS. “It was long thought that antiparticles would behave in the same way as particles in a mirror world made of antimatter, but since the 1960s we have known that quarks and antiquarks break this particle–antiparticle mirror symmetry.” https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn
