Gravity used to be the most dependable rule in the cosmic rulebook, the quiet background force that never changed its mind. Now a series of discoveries and bold claims are turning that certainty into ...

A new theoretical framework shows how subtle fluctuations in spacetime could be detected using existing interferometers.

Global climate models capture many of the processes that shape Earth's weather and climate. Based on physics, chemistry, ...

Scientists scanning the heart of the Milky Way have spotted a tantalizing signal: a possible ultra-fast pulsar spinning every 8.19 milliseconds near Sagittarius A*, the supermassive black hole at our ...

A clear look at how physics defines gravity, from Newton’s force-based model to Einstein’s view of curved spacetime, and why the distinction matters in modern science.

Physicists have long believed that detecting the particle of gravity—the graviton—was fundamentally impossible, with the ...

Quasicrystals are orderly structures that never repeat. Scientists just showed they can exist in space and time.

Theoretical research led by Professor Enrique Gaztañaga of the University of Portsmouth challenges the ...

The shape of the cosmos depends on a balance of two competing forces: the pull of gravity and the expansion driven by dark ...

A record-breaking gravitational wave signal let scientists "listen" to a distant black hole merger and put Einstein's gravity to its toughest test yet.

You might think galaxies can’t ever find each other in our runaway cosmos, but it turns out gravity can sometimes overcome ...
