Astronomers find the fastest spinning black hole to date

Web9 apr. 2006 · If the black hole does not spin, then η is only 5.7 percent. However, the faster the black hole spins, the greater η is. For the fastest possible spin, η is 42 percent, which means that nearly half the infalling mass gets transformed into energy. Thus, a black hole can change matter into far more energy than a normal star can.

Black Holes in Quasars Spin Fast by Ken Croswell

Web28 dec. 2016 · How Fast Does a Black Hole Spin? When astronomers measure a black hole’s spin, they report the value as a fraction of the maximum allowed spin. For example, the bigger member of the black hole binary in the quasar OJ 287 has a spin, labeled a, of 0.313, or 31.3% of its max. But what does that mean? http://kencroswell.com/BlackHolesInQuasarsSpinFast.html

WebHere we’re comparing the time passed in 24 hours near the black hole to how much time passes on Earth in this same period (so we’re taking Δτ=24 h, which is the time passed near the black hole and Δt is the time passed on Earth that we get from our formula above). WebIn most astrophysical environments I expect black holes to spin no faster than about 0.998 of the maximum. However, I can imagine situations--very rare or never in the real universe, but possible nevertheless--where the spin gets much closer to the maximum ...

Web14 mrt. 2014 · According to General Relativity a rotating black hole cannot be a point, for the reason you observe. A line bent round on itself forms a ring and is one candidate solution, spinning around its axis so it appears motionless. Oddly, an object may have a reasonably stable orbit through the ring without falling into the singularity. Web8 nov. 2024 · Currently, scientists only have two ways of measuring black holes - either by their mass or by their spin rate. A spin rate can be anywhere between 0 and 1: this black hole was spinning at the rate of 0.9. Einstein's theory further implies that if a black hole is spinning that fast, then it is capable of making space itself rotate.
