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 ...

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 they whirl around in low-Earth orbit, satellite configurations are far more sensitive to changes in Earth's gravity field ...

Researchers have found that bone and muscle mass are regulated by the altered gravity. The experiments were done in space using Kibo, an ISS module developed by JAXA, and on the ground. An ...
