Topologists Tackle the Trouble With Poll Placement
...time to vote. Empty areas completely surrounded by the shapes are called holes. The holes are where residents would be either making their way to the polls or waiting in...
What Is Quantum Teleportation?
...black holes, which have a shared interior — a kind of wormhole connecting the inside of these two black holes. And the paper by Einstein, [Boris] Podolsky and Rosen was...
What Is the Nature of Time?
...the Earth’s gravitational field, or the universe, or in very extreme conditions, like where there’s a very vast concentrations of mass that curve space in black holes. Then more flexible,...
To See Black Holes in Stunning Detail, She Uses ‘Echoes’ Like a Bat
...black holes. More than that, if we want to get at the question of how black holes grow, we need to look at black holes that are actively growing right...
How a New X-Ray Technique Sees Black Holes
Astrophysicist Erin Kara explores black holes by carefully tracking the gas and plasma swirling near their event horizons. Video: Emily Buder and Christopher Webb Young/Quanta Magazine; Photo: Katherine Taylor for...
Why Locusts Swarm, Humans Do Good and Time Marches On
...theoretical physicist Lenny Susskind assured me that every last qubit of quantum information will languidly leak from the black hole in Hawking radiation until the evaporation escalates and the black...
The Year in Physics
...and force scientists to reimagine how familiar cosmic objects came to be — things like stars and planets and black holes. Black holes are also at the center of one...
Extra-Long Blasts Challenge Our Theories of Cosmic Cataclysms
...heavy spinning black hole, the neutron star spirals in and the black hole shreds it over hundreds of orbits, leaving a heavier disk of material that the black hole needs...
A Century Later, New Math Smooths Out General Relativity
...black holes. This could occur even in a space with small amounts of matter, if it’s concentrated strongly enough. In a recent paper, Conghan Dong, a graduate student at Stony...
