Spaghetti science: What pasta reveals about the universe (bbc.com)
When you see pasta, your brain probably doesn't jump to the secrets of the universe. But for almost a century, world-leading physicists have puzzled over spaghetti's counterintuitive properties.
New high-definition images released of the baby universe (princeton.edu)
New research by the Atacama Cosmology Telescope (ACT) collaboration has produced the clearest images yet of the universe’s infancy — the earliest cosmic time yet accessible to humans.
Survey of physicists about the threat of vacuum decay (effectivealtruism.org)
TLDR: Vacuum decay is a hypothesized scenario where the universe's apparent vacuum state could transition to a lower-energy state. According to current physics models, if such a transition occurred in any location — whether through rare natural fluctuations or by artificial means — a region of "true vacuum" would propagate outward at near light speed, destroying the accessible universe as we know it by deeply altering the effective physical laws and releasing vast amounts of energy.
