How Einstein Lost His Bearings, and With Them, General Relativity
...proven especially acute for mathematicians who study the so-called black hole stability conjecture, which I wrote about in my recent article “To Test Einstein’s Equations, Poke a Black Hole.” Depending...
Mathematicians Tame Rogue Waves, Lighting Up Future of LEDs
...waves then interfere with each other in a bewildering number of ways. And, just as you can combine every color to get black, when you combine such a complicated mix...
‘Nasty’ Geometry Breaks Decades-Old Tiling Conjecture
...know if they could drive that number down. By the mid-1970s, Roger Penrose (who would go on to win the 2020 Nobel Prize in Physics for work on black holes)...
What Can Tiling Patterns Teach Us?
...had someone do one of those lightbox diffraction experiments where you poke holes in the paper. And so he had them go on a Penrose tiling and poke holes in...
Salamander’s Genome Guards Secrets of Limb Regrowth
...They wear their gills on the outside, a set of three feathery horns on each side of the head. Their four-fingered hands with black nails are delicate and vaguely human...
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...
