Quanta Writers and Editors Discuss Trends in Science and Math
...especially the role of black holes in the universe. But I would say, actually, what excites me most is that in this period of — kind of — turmoil and...
Galactic Beacons Get Snuffed Out in a Cosmic Eyeblink
...supermassive black holes’ lower-mass doppelgängers — turn inactive. When they’re accreting a lot of mass onto the black hole, their accretion disk is quite thin and luminous. But when that...
Universal Quantum Phenomenon Found in Strange Metals
...(The black hole pops out of the particle system like a hologram.) Remarkably, physicists find that black holes — incredibly dense, spherical objects whose gravity is so strong that not...
How Holography Could Help Solve Quantum Gravity
...black holes and the Big Bang, where extreme gravity operates at tiny scales. We hope you enjoyed this second episode from season two of Quanta’s In Theory video series. Season...
Without a Proof, Mathematicians Wonder How Much Evidence Is Enough
...complicated or forbidding to study directly. By creating a black hole analogue in a laboratory, you might be able to learn something about how real black holes behave without having...
Astronomers Creep Up to the Edge of the Milky Way’s Black Hole
...the black hole’s flickering, that motion would be linear, as blobs traveled outward and cooled, Eisenhauer said. If clumps in the disk around the black hole were responsible, the motion...
A Short History of the Missing Universe
...quasars — the bright cores of galaxies with active black holes at their center — using the new spectrograph at the Keck telescope in Hawaii. Tytler’s data helped researchers understand...
The End of Theoretical Physics as We Know It
...no one can calculate how they come together to make a proton. The equations just can’t be solved by any known methods. Similarly, a merger of black holes or even...
Black Hole Firewalls Could Be Too Tepid to Burn
String theorists elide a paradox about black holes by extinguishing the walls of fire feared to surround them. Despite its ability to bend both minds and space, an Einsteinian black...
