Physicists Rewrite the Fundamental Law That Leads to DisorderBy PHILIP BALL The second law of thermodynamics is among the most sacred in all of science, but it has always rested on 19th century arguments about probability. New arguments trace its true source to the flows of quantum information.

 | Life’s First Peptides May Have Grown on RNA StrandsBy YASEMIN SAPLAKOGLU For the past few decades, researchers have favored an “RNA world” theory of life’s origins, but a recent study breathes fire into the possibility of a more expansive “RNA-peptide world.”

 | Crisis in Particle Physics Forces a Rethink of What Is NaturalPodcast hosted by SUSAN VALOT;
Story by NATALIE WOLCHOVER For three decades, researchers hunted in vain for new elementary particles that would have explained why nature looks the way it does. As physicists confront that failure, they’re reexamining a longstanding assumption: that big stuff consists of smaller stuff.

 | The Big Reveal of the Milky Way's Supermassive Black HoleVideo by EMILY BUDER More than three years after the release of the first image of a black hole, scientists from the Event Horizon Telescope (EHT) shared an image of the supermassive specimen at the center of our own Milky Way galaxy. In this video, EHT's scientists explain the science behind the big discovery.

Good Habits
There is more to determining whether a planet is habitable than its proximity to its sun. For PBS Space Time Matt O’Dowd and Moiya McTier describe the “galactic habitable zone”: a range of distances from the galactic center with the right stellar densities and metallicities for life to thrive. Galactic-scale features also play a role in the propagation of life. In 2019 Rebecca Boyle wrote for Quanta about a simulation that showed that galaxy dynamics would aid potential alien civilizations in intragalactic travel.
Constant Evaluation
100 years ago, Alexander Friedmann changed cosmology when he considered how the evolution of the universe would have changed if Einstein’s “cosmological constant” had different values, writes Tom Siegfried for Science News. Today we’re reasonably certain the cosmological constant is positive, but we don’t know its exact value. In a 2021 Quanta article, Charlie Wood wrote about how related issues might be solved if we give up the sacred cosmological principle: that the universe is homogeneous and isotropic. |
