A closer look at the Lambda Cold Dark Matter model, its core components, supporting evidence, and why new observations are ...

Einstein–Rosen bridges may reflect a two-directional structure of time that preserves information and hints at a pre–Big Bang universe.

Neutron stars are ultra-dense remnants of massive stars that collapsed after supernova explosions and are made up mostly of subatomic particles with no electric charge (i.e., neutrons). When two ...

The loudest black hole collision ever recorded has just given Einstein’s theory of general relativity its hardest test so far. The event, dubbed GW250114, produced a record-smashing signal-to-noise ...

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

At the center of the Milky Way, close to the pull of a supermassive black hole, astronomers have found a strange new radio signal that behaves like a slow, steady clock. This object is more than an ...

An astrophysicist explains what wormholes are and how these theoretical space-time tunnels have popped up in the solutions to a set of decadesold equations.

If a pair of black holes coalesce into one, much of that vast energy can be released in a few seconds.

Studying the complete spectrum of the General Theory of Relativity and beyond: from the vast dimensions of the universe down to the incredibly tiny dimensions of strings - in Potsdam-Golm.

For the last 25 years, most scientists have believed that about 70% of the universe is formed by something called ‘’dark ...

Casimir cavities are mysterious spaces between microscopic metal plates in a vacuum. Areas of diminished energy between the plates cause them to push toward each other, as if trying to fill the ...

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 ...
