What Does the Fourth Dimension Actually Look Like?
...I look at a pair of pants, so just ordinary pants, how many holes are in there? LEVIN: Okay, so there’s one, two. STROGATZ: But some people wanna say three...
AI Starts to Sift Through String Theory’s Near-Endless Possibilities
...space-times surrounding exotic black holes. Perhaps, he speculated, computers could also solve for the metrics of Calabi-Yau space-times. “Everyone said, ‘Oh, no, you couldn’t possibly do that,’” Wiseman said. “So...
What Astronomers Are Learning From Gaia’s New Milky Way Map
...massive black hole at the center of the Large Magellanic Cloud. Full-size galaxies almost always harbor huge central black holes, which are of mysterious provenance. Their presence in some mini...
A Jewel at the Heart of Quantum Physics
...quantum field theory enters crisis mode in black holes. Black holes pack a huge amount of mass into an extremely small space, making gravity a major player at the quantum...
Math Duo Maps the Infinite Terrain of Minimal Surfaces

Any Single Galaxy Reveals the Composition of an Entire Universe
...The simulations also included rough treatments of complicated events like supernovas and jets that erupt from supermassive black holes. Ding’s neural network studied nearly 1 million simulated galaxies within these...
A New Tool for Finding Dark Matter Digs Up Nothing
...gravitational waves that pass through the planet, created by the distant collisions of black holes, only stretch and compress each mile of Earth’s surface by one-thousandth the diameter of an...
Physicists Use Quantum Mechanics to Pull Energy out of Nothing
...entanglement. Black holes shrink by emitting radiation entangled with their interiors, a process that can also be viewed as the black hole swallowing dollops of negative energy. Hotta noted that...
