“The Sombrero Galaxy as never seen before? Discovered by Pierre Méchain at the end of the 18th century, it is one of the sharpest and most spectacular images captured by the Hubble Space Telescope, especially because the angle at which it is seen from our planet creates a tremendously impressive visual effect.

THE LEGO KIT. “All visible matter in the Universe is made of fundamental building blocks, the elementary particles. The group of particles known as fermions consists of two types: quarks, which make up protons and neutrons; and leptons, namely, the electron, muon, tau particle and neutrino.” https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn

ANTIMATTER. “For each elementary particle, there is an antiparticle that has the same properties but opposite charge. The best-known example is the antielectron, or positron.” https://www.nature.com/articles/d41586-020-01000-9 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

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

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 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

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

MATTER>ANTIMATTER. “This imbalance, at a level of a few particles per 10 billion photons, is ultimately responsible for the existence of Earth, planets, stars and ourselves: if there were equal amounts of matter and antimatter, they would have destroyed each other in the early Universe and annihilated into photons. No matter would have remained.” https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn
