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

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 ...

In an astonishing feat of gravitational sleuthing, astronomers have found a mysterious, dense blob of invisible matter ...

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 ...

Researchers have discovered there was an anomaly in Earth's gravitational field between 2006 and 2008, potentially caused by ...

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 ...

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 ...

As the story goes, mathematician Sir Isaac Newton was sitting in an orchard after supper when he saw an apple fall from a tree. He wondered why apples always fall straight to the ground, instead of ...

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 ...
