Black Hole Spins can fit with 97.6% Fibonacci-Lucas-Number-Midpoints - A first look

by Stefan Geier et al.

1. "In late 2006, astronomers reported estimates of the spin rates of black holes in The Astrophysical Journal. A black hole in the Milky Way, GRS 1915+105, may rotate 1,150 times per second,[6] approaching the theoretical upper limit." (Wikipedia, 08.08.26: [6] Hayes, Jacqui (24 November 2006). "Black hole spins at the limit". Cosmos magazine. Archived from the original on 7 May 2012.

2. 1178.5 is the midpiint of the neighbouring Lucas number L15 and Fibonacci number F16: F16=987, L15=1363.

3. GRS 1915+105 spin fits with 97.6% the F16-L15 midpoint: 1150/1178.5 = 0.9758167 ~ 97.6%.

(Other sources: spin 950/s; 950/F16=0.96251 ~  96.2 %)

This corroborates, however weak, Geier's equations and Geier's equilibrium programme.

With additum 1 we conclude: Black holes obey often in at least one aspect Geier's equations and Geier's equilibrium programme.

Wikipedia, today: Yukterez (Simon Tyran, Vienna) - Own work: Diagram of the static limit (ergosphere) and the inner and outer event horizons of a rotating black hole. "a" is the Spin parameter of the rotating black hole; with a low spin-parameter the ergosphere converges to an ellipsoid, while with a high spin-parameter it resembles a pumpkin-shape. The axes are in units of GM/c².
