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 ...

Scientists may have found a new way to unlock the vast secrets of the Big Bang—the cosmic event thought to have kicked off the expansion of the universe billions of years ago. The revelation came in ...

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 ...
