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 ...

Such gravity variations are often caused by variations in the concentration of mass — more mass means more gravity. For ...

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 ...

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

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 ...

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 ...

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 ...

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 ...

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 ...

Two recent ultra-deepwater pipeline projects have encountered mass-gravity flows as significant geohazards. The pipelines are the Shell Malampaya Pipeline in the Philippines and the Gazprom Blue ...
