Scientists have used theloudest gravitational wave signal ever recorded to put Albert Einstein’s century-old theory of ...

This talk tells the story of symmetry in theoretical physics, and its interplay with developments in our understanding of gravity over the years. In this talk, McNamara explores the power of symmetry ...

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

Scientists confirm that clocks on Mars run faster than on Earth and will change global space navigation in the future ...

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 ...

General relativity helps explain the lack of planets around tight binary stars by driving orbital resonances that eject or destroy close-in worlds. This process naturally creates a “desert” of ...

Researchers believe they have found the signal of a pulsar, the ancient core of a rapidly spinning star, at the center of the Milky Way, near a supermassive black hole. This discov ...

Scientists hope to probe the nature of general relativity through a possible pulsar found in the center of the Milky Way, ...

The second reason is simple: location, location, location! The millisecond pulsar appears to be near Sagittarius A*, the ...

Ripples in space-time from a pair of merging black holes have been recorded in unprecedented detail, enabling physicists to test predictions of general relativity ...

Time only moves microseconds faster on the moon, so why would it need its own timezone? Learn how the moon's timezone plays a ...

Can Mars let humans age faster? It sounds more poetic than reality, but it may be true technically. Two identical clocks: One on Earth other on Mars, .
