They pull us in, literally and figuratively. Black holes — remnants of collapsed stars — have immense mass that curves spacetime so all paths lead inward. They also capture the popular imagination as ...

Scientists have simulated how M87*, the supermassive black hole at the center of the galaxy M87, powers its immense particle jet. The Frankfurt team’s FPIC code shows that magnetic reconnection, where ...

A bizarre, record-breaking neutrino detected in 2023 may have originated from an exploding primordial black hole—a relic from the early universe. Scientists suggest these black holes could carry a ...

A new simulation could help solve one of astronomy’s longstanding mysteries—how supermassive black holes formed so rapidly—along with a new one: What are the James Webb Space Telescope’s (JWST) ...

Last November, the Laser Interferometer Gravitational-Wave Observatory, or LIGO, picked up something odd. An automated alert flagged a merger where one of the objects involved had a mass lower than ...

The following is an extract from our Lost in Space-Time newsletter. Each month, we hand over the keyboard to a physicist or mathematician to tell you about fascinating ideas from their corner of the ...
