Extracting the rotational energy of a black hole would be more complicated, but still theoretically possible. In his 1969 article, Penrose described a mechanism that could directly utilize ...

Evidence that the universe is rotating was recently delivered by the James Webb Space Telescope (JWST), which found that ...

A trio of physicists from Princeton University, CIT's Jet Propulsion Laboratory and Spectral Sensor Solutions, all in the U.S., is proposing the possibility of generating electricity using energy ...

Scheeres' theory predicts that if a binary asteroid forms by rotational fission, the two can only escape from each other if the smaller one is less than 60 percent of the size of the larger asteroid.

The world is hungry for renewable sources of energy, which has led some scientists to ask the question: what about the rotation of the Earth? A new study reports that researchers have successfully ...

You can see those seasonal swings in this chart tracking changes to Earth’s rotation rate since the year 2000. As it shows, Earth has been picking up speed in the last few years, after slowing down ...

The Red Sox filled two rotation spots with bullpen games much of the summer to deal with starting pitchers on the injured list. Tanner Houck and Chris Sale are back and pitching again, but neither ...

The jets get an energy boost from the rotational energy of the black hole, they say in a paper published in Nature. Supermassive black holes pull in gas, dust and other interstellar material ...

To mitigate these inconsistencies, the filing proposes a system that converts rotational energy from the turbine into heat, which is then stored in a "low-heat-capacity" fluid.

DOWN THE DRAIN Water ripples can ricochet off a vortex (shown), gaining energy.Scientists have now observed this effect, known as rotational superradiance, for the first time. The effect is also ...
