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.

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 ...

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 ...

The puzzle Einstein and Rosen were addressing was never about space travel, but about how quantum fields behave in curved spacetime. I ...

Scientists use distant gamma ray bursts to prove that light maintains its constant speed, reinforcing Einstein's theory.

The universe has delivered the loudest gravitational wave ever recorded, and it appears to have given Einstein’s theory of general relativity one of i.

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

Scientists say that while ordinary crystals repeat precisely, quasicrystals maintain order even though their patterns fail to repeat perfectly.

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.

Charleston, SC, astronomy professor answers questions from high school students about wormholes, black holes, colonizing Mars, outer space odors and more.

The big bang wasn’t the start of everything, but it has been impossible to see what came before. Now a new kind of cosmology is lifting the veil on the beginning of time ...
