Astronomers Find Black Holes Stirring Up the Biggest Galaxies
After a space telescope disintegrated, astrophysicists had little hope of understanding how supermassive black holes agitate giant galaxies. Then they invented a hack.
Why the Laws of Physics Are Inevitable
By considering simple symmetries, physicists working on the “bootstrap” can rediscover the basic form of the known forces that shape the universe.
Black Hole Singularities Are as Inescapable as Expected
For the first time, physicists have calculated exactly what kind of singularity lies at the center of a realistic black hole.
Top Dark Matter Candidate Loses Ground to Tiniest Competitor
Physicists have long searched for hypothesized dark matter particles called WIMPs. Now, focus may be shifting to the axion — an ultra-lightweight particle whose existence would solve two mysteries at once.
Solution: ‘Randomness From Determinism’
Readers’ modifications of a bean machine showed how deterministic laws are capable of producing random-seeming behavior.
Are Saturn’s Rings Really as Young as the Dinosaurs?
A surprisingly youthful estimate of the age of the rings has stirred a backlash.
Hologram Within a Hologram Hints at Fate of Black Holes
Calculations involving a higher dimension are guiding physicists toward a misstep in Stephen Hawking’s legendary black hole analysis.
Neutrinos Lead to Unexpected Discovery in Basic Math
Three physicists stumbled across an unexpected relationship between some of the most ubiquitous objects in math.
Virginia Trimble Has Seen the Stars
How a young celebrity became one of the first female astronomers at Caltech, befriended Richard Feynman, and ended up the world’s foremost chronicler of the science of the night sky.
