In fact, only three factors can be used to define a black hole: its mass, its angular momentum and its electric charge. In ...

It seems obvious, then, that, cosmically speaking, everything spins—but this basic fact becomes downright bizarre in the head ...

If mature black holes had personalities, they would be extremely introverted. They don’t let anything out – not light, not ...

TPU researchers, together with their colleagues from the Joint Institute for Nuclear Research, have developed a model that ...

Astronomers have stumbled upon an incredible cosmic chain reaction: a young star launched a high-speed jet that ignited an ...

Angular momentum does not necessarily need to involve "real" bodily rotation in this context: Magnetic materials even have angular momentum when, seen from outside, they are at rest.

When a magnetic material is bombarded with short pulses of laser light, it loses its magnetism within femtoseconds (10 –15 seconds). The spin, or angular momentum, of the electrons in the material ...

The angular momentum depends on both the angular velocity and the mass distribution of the object. You can change this angular momentum by exerting a torque (a twisting force)—but with no ...

To compensate and keep angular momentum constant, the washer's angular velocity has to increase. The reverse happens when you loosen the string and allow the washer to move out farther.
