In 2023, scientists detected the gravitational waves from a black hole collision that seemed impossible. New research finally explains how this "forbidden" black hole came to be, and what it can teach us about these extreme objects.

Doppler cloak confuses radars by altering the phase of incoming radar waves in real time.

New 3D printed scaffolds more accurately mimic the structure and behaviour of natural bone.

A new physics paper proposes modifications to Einstein’s theory of relativity that could solve one of the biggest issues about our understanding of the Big Bang.

Stephen Hawking's theory of black hole evaporation clashes with the laws of quantum mechanics. A new paper finds a way around this paradox, provided that the universe has seven dimensions.

Researchers have observed unusual patterns of heat flow inside quantum computers, revealing behaviors that defy classical thermodynamics.

The universe may not be perfectly uniform after all, a new series of papers hints. If confirmed, this could upend a nearly 100-year-old model of cosmology.
