Gravity used to be the most dependable rule in the cosmic rulebook, the quiet background force that never changed its mind.

New simulations performed on a NASA supercomputer are providing scientists with the most comprehensive look yet into the maelstrom of interacting magnetic structures around city-sized neutron stars in ...

Wide binary stars as direct probes of the nature of gravity at low acceleration weaker than about 1 nanometer per second squared have been hotly debated. The nature of gravity at such low acceleration ...

The triangle ain't equilateral. Also, I read the jar drawing as being constant speed, not constant acceleration. Each consecutive falling object is at a constant horizontal distance. At the small ...

In the zero-gravity airplanes or vomit comet, why does stuff behave like there is no gravity when it is just falling? – Austin B., 11, Scranton, Pennsylvania I have flown many times in zero-gravity ...
