Newfound Wormhole Allows Information to Escape Black Holes
Physicists theorize that a new “traversable” kind of wormhole could resolve a baffling paradox and rescue information that falls into black holes.
Neutron-Star Collision Shakes Space-Time and Lights Up the Sky
Astronomers have for the first time matched a gravitational-wave signal to a kilonova’s burst of light, observations that will “go down in the history of astronomy.”
Ultra-Powerful Radio Bursts May Be Getting a Cosmic Boost
Repeating radio bursts are among the most mysterious phenomena in the universe. A new theory explores how some of their puzzling properties can be explained by galactic lenses made of plasma.
How the Hidden Higgs Could Reveal Our Universe’s Dark Sector
The universe has not cooperated with physicists’ hopes. In desperation, many are looking for new ways to search for surprises at the Large Hadron Collider.
To Solve the Biggest Mystery in Physics, Join Two Kinds of Law
Reductionism breaks the world into elementary building blocks. Emergence finds the simple laws that arise out of complexity. These two complementary ways of viewing the universe come together in modern theories of quantum gravity.
Quantum Theory Rebuilt From Simple Physical Principles
Physicists are trying to rewrite the axioms of quantum theory from scratch in an effort to understand what it all means. The problem? They’ve been almost too successful.
For Astronomers, Neutron Star Merger Could Eclipse Eclipse
Even as the solar eclipse was mesmerizing millions, astronomers were training their space- and land-based telescopes on a far more violent astrophysical event.
