Is time something that flows — or just an illusion? Exploring space-time as either a fixed “block universe” or a dynamic fabric reveals deeper mysteries about existence, change, and the very nature of ...

Fragments of energy may be the fundamental building blocks of the universe. The theory combines the ideas of particles and waves into a concentration of energy that flows throughout space and time.

Since that day, LIGO — composed of two highly sensitive laser interferometers located in Hanford, Washington and Livingston, ...

Hawking’s theory for the first time in history. The observations by gravitational waves reveal that black holes do in fact ...

A new emulator is tackling the near-impossible task of mapping the universe's large-scale structure without sacrificing ...

Mathematical quirks of our universe have led some cosmologists to wonder whether the cosmos was actually born in a black hole ...

Scientists have captured the clearest signal yet of a black hole collision, confirming Stephen Hawking's theory.

Textbooks give strange, imprecise explanations of where things happen in quantum mechanics. Consistency with gravity needs a fresh approach.

From early experiments with lanterns to Einstein’s revelations about space and time, the speed of light has proven to be far ...

Ten years after scientists first detected gravitational waves emerging from two colliding black holes, the LIGO-Virgo-KAGRA ...

Two black holes collided 1.3 billion light years from Earth, creating a 'ringing,' which in turn allowed astrophysicists to ...

The theory says two black holes that merge will have the same or larger surface area than what the pair started out with.
