A Cosmic-Ray Hunter Takes to the Sky
...that the bigger the better, so the supermassive black holes are usually a little bit ahead. It could be somewhere in the middle: intermediate-mass black holes. Or ultrahigh-energy cosmic rays...
The Quantum Thermodynamics Revolution
...to everything else: the sun, black holes, living beings and the entire universe. The theory is so simple and general that Albert Einstein deemed it likely to “never be overthrown.”...
Discoveries Fuel Fight Over Universe’s First Light
...evidence that supermassive black holes existed hundreds of millions of years before anyone thought possible. The new discoveries should make clear just how much black holes contributed to the reionization...
Latest Black Hole Collision Comes With a Twist
...immediately detected gravitational waves from a black-hole merger, no one knew whether it would see merging black holes, merging neutron stars, black holes merging with neutron stars or none of...
Dark Matter Recipe Calls for One Part Superfluid
...field with two colliding black holes and you’ll create gravitational waves. Likewise, if you poke a superfluid, you’ll produce phonons — sound waves in the superfluid itself. These phonons give...
Rainer Weiss, Remembering the Little Room in the Plywood Palace
...faraway collision of two black holes. Along with the physicists Kip Thorne and Ron Drever, Weiss founded the Laser Interferometer Gravitational-Wave Observatory (LIGO), the experiment that in February 2016 announced...
Where Gravity Is Weak and Naked Singularities Are Verboten
...a universe like ours. Always, singularities lay at the centers of black holes — sinkholes in space-time that are so steep that no light can climb out. He told his...
Juan Maldacena, Pondering Quantum Gravity by the Pond
...2013 with a cryptic message first delivered in an email to fellow physics giant Leonard Susskind: “ER = EPR.” It meant that wormholes, hypothetical connections between far-apart black holes also...
Strange Noise in Gravitational-Wave Data Sparks Debate
...collision of two black holes. The team held a press conference in Washington to announce the landmark findings. They also released their data. Now a team of independent physicists has...
