CERN Physicists Find Key Piece of the Matter-Antimatter Puzzle

gizmodo.com Gayoung Lee 2025-07-24 23:00:42

All matter in our universe has an evil twin: antimatter. Cosmological models suggest that the Big Bang should have created equal amounts of matter and antimatter that cancel each other out. But for reasons physicists still aren’t completely sure about, that didn’t happen. As a result, our universe today hosts slightly more matter than antimatter—our very existence being clear, physical proof. Now, we might be one step closer to explaining why there’s an imbalance between matter and antimatter,

There could be “dark main sequence” stars at the galactic center

arstechnica.com Unknown 2025-07-25 20:30:58

For a star, its initial mass is everything. It determines how quickly it burns through its hydrogen and how it will evolve once it starts fusing heavier elements. It's so well understood that scientists have devised a "main sequence" that acts a bit like a periodic table for stars, correlating their mass and age with their properties. The main sequence, however, is based on an assumption that's almost always true: All of the energy involved comes from the gravity-driven fusion of lighter elemen

Do You Need a Box Spring for Your Modern-Day Mattress? (2025)

wired.com Julia Forbes 2025-07-28 03:32:00

You're probably familiar with a box spring, the simple wood frame with springs that acts as a support base under older mattresses. It's not a highly technical piece of equipment like a smart bed (or a trampoline, wouldn't that be fun)—this kind of mattress foundation has persisted through the ages solely due to its simple and durable design. But have you noticed you may not be seeing them as often nowadays? In my opinion as a career mattress tester, contemporary mattresses are on their way to m

Dozens of ‘Ghost Galaxies’ Are Orbiting the Milky Way, Astronomers Suspect

gizmodo.com Margherita Bassi 2025-07-28 23:35:25

The Lambda Cold Dark Matter (LCDM) theory suggests that most galaxies are low-mass dwarf galaxies, many of which orbit larger galaxies like the Milky Way. More broadly, the LCDM represents our best understanding of how the universe works. But there’s a problem. According to the theory, the Milky Way should have significantly more satellite galaxies than scientists have observed with telescopes and predicted with computer simulations.
