ASYMMETRY ORIGIN. “How did this tiny excess arise from an initial Universe that was perfectly symmetrical? The amount of CP violation observed in quarks is not enough to cause it, so scientists have looked at leptonic CP violation in a well-studied mechanism called leptogenesis.” (CP = charge-conjugation parity-reversal). https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn

THE BEGINNING. “In models introduced to explain the observed neutrino masses, hypothetical heavy partners to neutrinos would have been copiously present in the early Universe and subsequently decayed. In the presence of CP violation, these decays could have generated the observed matter–antimatter asymmetry.” (CP = charge-conjugation parity-reversal). https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn

ANTICIPATION. “The discovery of substantial leptonic CP violation would be groundbreaking. Its observation, together with evidence that a quantity known as lepton number has been violated (that is, not conserved), would provide strong circumstantial evidence for leptogenesis as the origin of the matter–antimatter imbalance.” (CP = charge-conjugation parity-reversal). https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn

TOOL. “Leptonic CP violation is elusive, but can be searched for using neutrinos. These fundamental particles are remarkably reluctant to interact with ordinary matter, making them very hard to detect. They are the least understood known particle.” (CP = charge-conjugation parity-reversal). https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn

NEUTRINOS. “Despite this, they are ubiquitous: your average coffee mug contains around 100,000 of the ‘cold’ neutrinos that permeate the Universe, and many times more produced by the Sun.” https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn

ANIMATED UNIVERSE. “Even a photon has some degree of consciousness. The idea is not that photons are intelligent or thinking. [...] But the thought is maybe photons might have some element of raw, subjective feeling, some primitive precursor to consciousness.” (Chalmers 2014). https://link.springer.com/chapter/10.1007/978-3-030-03633-1_14 View in LinkedIn

At the center of the Lagoon Nebula, imaged by Hubble in 2018, a young star 200,000 times brighter than our Sun is blasting powerful ultraviolet radiation and stellar winds, carving shapes out of the surrounding gas and dust: https://lnkd.in/eS8tB3Bp https://lnkd.in/e5MaXFXg View in LinkedIn

THE MENU. “Neutrinos come in three types (flavours), determined by their associated charged lepton, whether that is an electron, a muon or a tau particle. It was long thought that neutrinos were massless.” https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn

NEUTRINO MASS. “However, the discovery of neutrino oscillations by the Super-Kamiokande experiment in 1998, and by the Sudbury Neutrino Observatory in 2002, proved that these particles do have mass.” https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn

WONDERLAND. “Neutrino oscillation is the phenomenon whereby neutrinos change from one flavour to another as they travel. It is a quantum-mechanical effect that arises because each neutrino flavour is effectively a mixture — a quantum superposition — of three states that have different masses.” https://www.nature.com/articles/d41586-020-01000-9 View in LinkedIn
