In 2007, a peculiar gravity signal was detected from deep within Earth, suggesting rapid changes near the planet’s core. This ...

Researchers looking through data from NASA and the German Aerospace Center (DLR)'s Gravity Recovery and Climate Experiment (GRACE) have found an odd gravity anomaly over the Atlantic Ocean. Attempting ...

A bundle of magnets and glass had a slight but detectable gravitational pull, pushing scientists closer to the boundary between classical and quantum physics. reading time 3 minutes Despite keeping us ...

Satellites detected a strange gravity signal off the coast of Africa nearly 20 years ago, suggesting something unusual had ...

Something seems to be missing from the universe, and the favored model of physics calls it “dark matter” – but despite a century of searching, it remains a no-show. A new paper proposes an alternative ...

Astronomers discover a low-mass dark object through gravitational lensing and multiple radiotelescopes across Earth.

Although we take a lot of scientific knowledge for granted today, each of the basics – whether it be about light, gravity, mass or the shape of the Earth – had to be theorized and experimentally ...

What is gravity without mass? Both Newton's revolutionary laws describing its universal effect and Einstein's proposal of a dimpled spacetime, we've thought of gravity as exclusively within the domain ...

Some clusters of galaxies may not need dark matter in order for their physics to work. In new research, a physicist describes a “shell singularity,” where gravity applies without mass. Today’s ...

Mass is mass is mass. Physicists have three different definitions of mass, all thought to be equivalent. Measurements of the distance between Earth and the moon confirm that two of those masses are ...

Energy-momentum distribution remains a fundamental yet challenging aspect of theoretical physics. In general relativity, the localisation of gravitational energy is obscured by the equivalence ...
