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...
Physicists Debate Hawking’s Idea That the Universe Had No Beginning
...they met in Cambridge for long periods of collaboration. The duo’s theoretical investigations of black holes and the mysterious singularities at their centers had turned them on to the question...
Social Distancing From the Stars
...my most exciting research — explaining odd variations in the brightness of Betelgeuse, studying the home galaxies of newborn black holes halfway across the universe, finding a strange new star...
Contemplating the End of Physics
...in 2016) and the first image of a black hole’s event horizon in 2019. All three were rare instances of scientific mega-events that landed on the front pages of newspapers...
Federico Ardila on Math, Music and the Space of Possibilities
...so I think our campus is about 30% white, 30% Latino, 25% Asian, 10% black, something like this. Also, gender-wise, there’s — you’ll see the whole gender spectrum, and there’s...
Astronomers Say They Have Spotted the Universe’s First Stars
...can produce a similar helium II signature, including scorching disks of material that swirl around black holes. Wang thinks his team can rule out a black hole as the source...
How to Tame the Endless Infinities Hiding in the Heart of Particle Physics
...more than glorified photocopies. Oversize mathematical symbols scrawled in thick black ink frequently interrupt the neatly typed sentences. The text is also written in French, an inconvenience for researchers in...
The Two Faces of Space-Time
...in the real universe, too. “The whole game of understanding quantum gravity is to figure out how all of this bulk physics, the interior of black holes, is mapped into...
What Is Entropy? A Measure of Just How Little We Really Know.
...what entropy means in black holes. “The observational entropy framework provides much more clarity,” said Philipp Strasberg, a physicist at the Autonomous University of Barcelona, who recently included it in...
