The Hidden Heroines of Chaos
...a sharp pencil. “I’d poke holes for ones, and I’d cover up with Scotch tape the others,” she said. “He just got a kick out of it.” There were desks...
Did the Chicken Come First or Is It Turtles All the Way Down?
...further, speculating that inside black holes, universes may give rise to baby universes, each with slightly different laws and constants from its parent. These baby universes would persist longer if...
Robbert Dijkgraaf on Exploring Quantum Reality
...all these possible shapes, think of it as a large sculpture gallery where we have all these possibly beautifully curved spaces, of cosmologies or black holes or, you know, combinations...
The Hidden Magnetic Universe Begins to Come Into View
...objects called blazars located behind voids. Blazars are bright beams of gamma rays and other energetic light and matter powered by supermassive black holes. As the gamma rays travel through...
The Hidden Structure of the Universe
...substance as pervasive as the pre-Einsteinian aether, and just as poorly understood. Physicists probing the paradoxes of black holes have grown convinced that there’s a fundamental connection between information and...
The Webb Space Telescope Will Rewrite Cosmic History. If It Works.
...stars, to learn about the invisible matter whose gravity coaxed them into being, and about the roles of magnetism and turbulence, and how enormous black holes grew and worked their...
Four Years On, New Experiment Sees No Sign of ‘Cosmic Dawn’
...time, the first stars collapsed into black holes. The hot gas swirling around these black holes generated X-rays that heated hydrogen clouds throughout the universe, increasing the rate of 21-centimeter...
Physicists Pin Down How Quantum Uncertainty Sharpens Measurements
...Yunger Halpern and other theorists showed that Kirkwood-Dirac negativity also underlies quantum behavior in contexts besides metrology, including quantum thermodynamics and fast information scrambling in black holes. The researchers say...
In a Monster Star’s Light, a Hint of Darkness
...images of quasars — blazing beacons of light emitted by matter falling into black holes — and found evidence for dark halos as small as hundreds of millions of solar...
