A Glimpse Through a Cosmic Keyhole
...galaxies, meaning that they have jets of material streaming out in two directions, probably powered by the supermassive black holes spinning at the galaxies’ centers. (The jets emit radio light...
Janna Levin’s Theory of Doing Everything
...by way of your research on black holes. Could you talk about this concept you’ve been developing — the black-hole battery? It started really naively. A neutron star has a...
Michael Atiyah’s Imaginative State of Mind
...comes from the entire mass of the universe. It doesn’t cancel itself out, it doesn’t have positive or negative value, it all adds up. So however far away the black...
After Black Holes Collide, a Puzzling Flash
...of black holes that ultimately merge into one. A similar scenario has been used to explain how colliding black holes could create a gamma-ray burst. “To produce a gamma-ray burst...
The Quantum Secret to Superconductivity
...matte-black ceramic in a class of materials called cuprates that are the most potent superconductors known. The findings, reported today in the journal Nature, provide a major clue about the...
From Einstein’s Theory to Gravity’s Chirp
...reason we can see it from the two black holes is that they are closer together than two stars could ever be. The black holes are so tiny and yet...
Gravitational Waves Discovered at Long Last
...whispers of these black-hole origin stories. Judging by its shape and size, that first, loudest chirp originated about 1.3 billion light-years away from the location where two black holes, each...
Taming Superconductors With String Theory
...to apply his insights to high-temperature superconductors themselves. Quanta Magazine spoke with Sachdev about how the electrons in high-temperature superconductors are related to black holes, his recent success with graphene,...
String Theory Meets Loop Quantum Gravity
...requiring a black hole to let information escape would destroy the delicate structure of empty space around the black hole’s horizon, thereby creating a highly energetic barrier — a black...
