Physicists in Spain and the US have shown that the orbital angular momentum, or twistedness, of light can be made to vary rapidly in time. The researchers demonstrated what they call “self-torque” by ...

In our solar system, the giant gas planets (Jupiter, Saturn, Uranus, and Neptune) spin more rapidly on their axes than the inner planets do and possess most of the system's angular momentum. The ...
