Astronomers Say They Have Spotted the Universe’s First Stars
...can produce a similar helium II signature, including scorching disks of material that swirl around black holes. Wang thinks his team can rule out a black hole as the source...
How to Tame the Endless Infinities Hiding in the Heart of Particle Physics
...more than glorified photocopies. Oversize mathematical symbols scrawled in thick black ink frequently interrupt the neatly typed sentences. The text is also written in French, an inconvenience for researchers in...
Experiment Reaffirms Quantum Weirdness
...black holes, for instance, suggests that the stronger the gravity in a volume of space-time, the fewer bits can be stored in that region. Could gravity be reducing the number...
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...
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...
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...
Moonshine Link Discovered for Pariah Symmetries
...symmetry groups to special classes of “weight 3/2” modular forms, objects that also show up in natural counting functions for black holes and for higher-dimensional generalizations of strings called “branes.”...
Ultra-Powerful Radio Bursts May Be Getting a Cosmic Boost
...What could possibly be making such blasts? Astrophysicists imagined one-off cataclysms — perhaps collapsing stars, or colliding black holes — which would seem to be the only way to generate...
Troubled Times for Alternatives to Einstein’s Theory of Gravity
...principle, which states that very dense strong-gravity objects such as neutron stars or black holes “fall” in the same way when placed in a gravitational field. (On Earth, the more...
