An unusually massive black hole in the very early universe may be a kind of exotic, star-less black hole first theorised by Stephen Hawking. In August, Boyuan Liu at the University of Cambridge and ...
A supermassive black hole that’s 10 million times the mass of the Sun is hurtling through space, leaving a trail of gas that’s spawning newborn stars in its wake. Astronomers have long theorized about ...
Two colossal black holes among the most massive ever seen collided in deep space, creating gravitational waves that rippled across the cosmos and shook the foundations of astrophysical theory.
A visionary plan proposes sending a paperclip-sized spacecraft, powered by Earth-based lasers, to a nearby black hole within a century. Led by astrophysicist Cosimo Bambi, the mission would test the ...
Some things in cosmology may simply be unknowable. Why is there something rather than nothing? What lies outside the universe? What is inside a black hole? That last one has been niggling at ...
The LIGO-Virgo-KAGRA (LVK) Collaboration has detected the merger of the most massive black holes ever observed with gravitational waves using the LIGO observatories. The powerful merger produced a ...
On Sept. 14, 2015, physicists attained the long-sought goal of detecting gravitational waves, the shockwaves spewed out by such cataclysmic events as the violent merger of two black holes. Now, in the ...
Black holes are known for swallowing everything around them, but some of them also ...
