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 ...

A study of 300,000 galaxies confirms that gravity follows Newton's law and deepens the mystery of dark matter.

Cosmic viewer The Atacama Cosmology Telescope in Chile was used by the team to observe gravitational interactions between ...

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 ...

Gravity behaves predictably in your daily life. Drop a ball, and it falls. Planets loop around stars. On paper, the same ...

A new study suggests that certain 'quantum collapse models'—which posit that wavefunction collapse happens spontaneously—could be tied to gravity, introducing a tiny intrinsic uncertainty in time ...

Wide binary stars with separation greater than about 2000 astronomical units are interesting natural laboratories that allow a direct probe of gravity at low acceleration weaker than about 1 nanometer ...

Caltech engineer Mory Gharib was poring over the digitized notebooks of Leonardo da Vinci one day, looking for sketches of flow visualization to share with his graduate students for inspiration.
