Scientists have discovered that under the right conditions, a gummy bear-like ball can roll down a vertical wall all by itself—upending a core assumption in physics.

The team’s orb rolled vertically at a rate of about 0.5 millimeters per second. Regardless, Mitra and colleagues wrote that their observation “challenges our basic understanding of physics,” with ...

Other ways the Sphere depends on physics and mathematics are described on its website. It notes the importance of π for determining the properties of a sphere and shows the maths behind the Sphere’s ...

Researchers from the University of Waterloo have achieved a feat previously thought to be impossible—getting a sphere to roll down a totally vertical surface without applying any external force.

According to Physics, Dyson Spheres Could Totally Exist, Scientist Says. ... A ring or sphere could, apparently, be stable if surrounded by the right sizes and gravities of other stars.

Alexandru Lupsasca and Michael Johnson won the physics prize for their work on photon spheres — weird rings of light around black holes that may reveal a theory of quantum gravity.
