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.

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 ...

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

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.

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

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

A new Big Bang model does away with speculative elements, putting gravitational waves at the forefront of the creation of ...

A fringe new theory suggests that time is the fundamental structure of the physical universe, and space is merely a byproduct. According to Gunther Kletetschka, a geologist — not a physicist, you'll ...

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