WebApr 17, 2024 · Within the ergosphere, the black hole's rotation drags space-time along with it and everything is forced to move in the same direction at nearly speed of light. This creates a natural laboratory more extreme than any possible on Earth. The faster the black hole spins, the larger its ergosphere becomes, which allows high-energy collisions ... WebMar 3, 2024 · Black holes are created when a massive star completely collapses as a result of its own gravity. The star's mass is compressed into an infinitely small space, causing …

WebFeb 13, 2014 · Imagine the event horizon of a black hole as a sphere in space, and then surrounding this black hole is the ergosphere. The faster the black hole spins, the more this ergosphere flattens out. WebYou can think of the ergosphere as a region where you would have to move faster than the speed of light to stand still. Inside the ergosphere, observers are forced to co-rotate with the black hole. A useful concept for thinking about trajectories in Kerr spacetime are the orthonormal "zero angular momentum observer" (ZAMO) frames.

WebDec 2, 2024 · When representing the ergosphere or the external event horizon of a black hole, it is often not taken into account that the coordinates used (if space-time is Kerr, the most usual are those of Boyer-Lindquist) have no physical meaning, in the sense that they do not allow us to "see" what the real form of such spatial hypersurfaces would be if ...

The size of the ergosphere, the distance between the ergosurface and the event horizon, is not necessarily proportional to the radius of the event horizon, but rather to the black hole's gravity and its angular momentum. A point at the poles does not move, and thus has no angular momentum, while at the equator … See more The ergosphere is a region located outside a rotating black hole's outer event horizon. Its name was proposed by Remo Ruffini and John Archibald Wheeler during the Les Houches lectures in 1971 and is derived from the Greek … See more A suspended plumb, held stationary outside the ergosphere, will experience an infinite/diverging radial pull as it approaches the static limit. At some point it will start to fall, resulting in a gravitomagnetically induced spinward motion. An … See more As a black hole rotates, it twists spacetime in the direction of the rotation at a speed that decreases with distance from the event horizon.
