In 2023, physicists were awed to find nearly imperceptible ripples in the fabric of space and time — united as an entity known as spacetime. They were ripples discovered in association with ...

Gravitationally speaking, the universe is a noisy place. A hodgepodge of gravitational waves from unknown sources streams unpredictably around space, including possibly from the early universe.

This illustration shows a stage in the merger of two galaxies that forms a single galaxy with two centrally located supermassive black holes surrounded by disks of hot gas. The black holes orbit each ...

The study of black hole thermodynamics has evolved into a vibrant field that explores the deep connections between gravity, quantum mechanics and statistical physics. Black holes, once regarded as ...

Similar to the ripples produced from dropping a stone in water, the collision of large celestial objects, such as black holes, generates gravitational waves—ripples in the fabric of space-time. A ...
