Building Codes for Bacterial Cities
...had engineered a small plastic slab studded with holes, like the world’s tiniest slice of Swiss cheese, called a microfluidic chip. It was meant to resemble the porous environments, such...
Eva Silverstein’s Spirals and Strings
...down sensible equations about what might happen inside black holes or during the Big Bang. But string theory describes invisibly tiny details of reality — vibrating strings at the hearts...
Subhash Khot, Playing Unique Games in Washington Square Park
...and a special quantum theory describing particles on the bottle’s rigid surface, which seems to project the dynamic interior like a hologram. Maldacena’s discovery has enabled physicists to probe black...
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...
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...
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...
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...
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...
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...
