How Modern and Antique Technologies Reveal a Dynamic Cosmos
...region that features a binary system of mammoth yet compact objects. There, two supermassive black holes and their surrounding accretion disks are locked in a dance that will eventually merge...
Monster Neutrino Could Be a Messenger of Ancient Black Holes
...have been spikes in the density of space-time that were so high that they would have collapsed into black holes. These black holes would have spanned a range of masses,...
The Year in Physics
...unique. It singlehandedly upends notions about the young universe. Black holes were thought to have come along only after the formation of galaxies, once stars gravitationally collapsed into black holes...
Cosmic Paradox Reveals the Awful Consequence of an Observer-Free Universe
Encouraged by successes in understanding black holes, theoretical physicists are applying what they’ve learned to whole universes. What they’re finding has them questioning fundamental assumptions about how physics ought to...
New Proofs Probe Soap-Film Singularities
...— in proofs of important conjectures in geometry and topology, in the study of cells and black holes, and even in the design of biomolecules. “They’re very beautiful objects to...
Carlo Rovelli’s Radical Perspective on Reality
...research is wide-ranging, running the gamut from quantum information to black holes, and often delves into the history and philosophy of science. In the late 1980s, he helped develop a...
A Single, ‘Naked’ Black Hole Rewrites the History of the Universe
...of the galaxy formation process, which did not start with black holes. Black holes were thought to have come along only after a galaxy’s stars gravitationally collapsed into black holes...
Astrophysicists Find No ‘Hair’ on Black Holes
...a quantum combination, or superposition, of many different configurations of space-time, making the black hole’s edges fuzzy. Other ideas include “gravastars” that resemble black holes but are surrounded by shells...
Why Did The Universe Begin?
...made that black holes radiate, that quantum processes are responsible for this, and that this radiation could be captured by purely spatial geometries. And that was the inspiration to try...
