After a three-year hiatus, scientists in the U.S. have just turned on detectors capable of measuring gravitational waves – tiny ripples in space itself that travel through the universe. Unlike light ...

The concept of spacetime, first described in Einstein's theory of general relativity, has since been widely studied by many ...

Researchers have designed a new type of gravitational wave detector that operates in the milli-Hertz range, a region untouched by current observatories. Built with optical resonators and atomic clocks ...

Physicists from Adolfo Ibáñez University and Columbia University have identified stable, 'frozen-in' gravitational structures that remain preserved as spacetime evolves. Using analogies from fluid ...

A snapshot of the 3D gravitational waveform from a general relativistic simulation of binary black holes. Gravitational waves from such binary mergers are routinely observed by LIGO. With space ...

A better understanding of the inner workings of neutron stars will lead to a greater knowledge of the dynamics that underpin the workings of the universe and also could help drive future technology. A ...

The newly detected gravitational wave background could be the result of supermassive black hole binaries that orbit each other for a few million years before merging. By now you’ll have seen the news ...

Gravitational-wave observatories have released their latest catalogue of cosmic collisions, bringing their total number of detections to 90. The new crop of 35 events includes one featuring the ...

Astronomers have confirmed a rare dual quasar system, J2037–4537, from just 1 billion years after the Big Bang, shedding light on early galaxy and black hole growth. High-resolution ALMA observations ...

Decades ago physicists realized that gravitational waves are no mere passing phenomenon. Instead those ripples in space should leave behind permanent marks: a fixed distortion in their wake. So far ...
