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

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.

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

If the pulsar is confirmed, it could enable more precise measurements of the space-time around the galaxy’s central supermassive black hole ...

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

“For the last 20 years, people believed that the cosmological constant is positive, and the universe will expand forever,” says Tye, a professor emeritus at Cornell. A positive constant acts like a ...

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

It’s unclear whether science as a discipline—and scientists as people—will ever be able to answer some questions definitively ...

Harry O'Mara, Luis Enrique Rosas Hernandaz, Sachini Withanage, Hemanta Pradhan and James Mangum share what they have been able to accomplish with the support of the Hughes family in the following ...

For many critics of religion, particularly within atheist circles, the Big Bang theory is frequently presented as a decisive scientific evidence against belief in God and the biblical doctrine of ...

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

Hypothetical dark matter stars known as "boson stars" could leave telltale ripples across the cosmos, offering researchers a new way to probe the invisible forces shaping the universe. In 2019, a ...
