The theory combines the ideas of particles and waves into a concentration of energy that flows throughout space and time. The researchers used the theory to answer two problems solved by Einstein.

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 ...

A radical new theory regarding the origin of the universe suggests that gravitational waves, tiny ripples in spacetime first ...

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

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.

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

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

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

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

Astronomers detected in unprecedented detail a collision between two black holes. Their observations confirm predictions made ...

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

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