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 ...

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 ...

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

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.

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

"GW250114 is the loudest gravitational wave event we have detected to date; it was like a whisper becoming a shout." ...
