Mathematicians Attempt to Glimpse Past the Big Bang
...Observatory in Greenwich. Something similar happens at the boundary of mathematical models of black holes. The equations that describe spherical nonrotating black holes, worked out by the physicist Karl Schwarzschild...
Where Do Space, Time and Gravity Come From?
...black hole, all of the information, all the quantum mechanical information inside a black hole, can in certain circumstances be thought of as spread out on the boundary of the...
Neutron-Star Collision Shakes Space-Time and Lights Up the Sky
...discovery that earned the experiment’s architects the Nobel Prize in Physics this month. Three more signals from black hole collisions followed the initial discovery. Yet black holes don’t give off...
‘Crazy’ Supernova Looks Like a New Kind of Star Death
...pair-instability, at which point, finally, they gravitationally collapse into black holes. (If Woosley’s theory is correct, there ought to be an absence of black holes over a certain mass range,...
The Year in Physics
...black holes gets destroyed and can never be retrieved. He lost that bet; physicists now believe information somehow escapes black holes. But how it gets out — a question raised...
How the Bits of Quantum Gravity Can Buzz
...extreme places: around the time of the Big Bang, or in the heart of black holes. “The problem with black holes is that they’re black, and so nothing comes out,”...
In a Multiverse, What Are the Odds?
...encountered the measure problem in the 1990s as a graduate student working with Stephen Hawking, the doyen of black hole physics. Black holes prove there is no such thing as...
Whisper From the First Stars Sets Off Loud Dark Matter Debate
...group looked at black holes as a possible explanation, since black holes are the brightest extragalactic radio sources in the sky. Yet black holes also produce other forms of radiation,...
The Simple Idea Behind Einstein’s Greatest Discoveries
...is still as productive as it once was. The flashier fruits of Albert Einstein’s century-old insights are by now deeply embedded in the popular imagination: Black holes, time warps and...
