Rotational Brownian motion (astronomy) supermassive black holes at the centers of galaxies. Perturbations from passing stars can alter the orbital plane of such a binary, which in turn alters the direction of the spin axis of the single black hole that forms when the two coalesce. Rotational Brownian motion is often observed in N-body simulations of galaxies containing binary black holes. The massive binary sinks to the center of the galaxy via dynamical friction where it interacts with passing stars. The same gravitational perturbations that induce a random walk in the orientation of the binary, also cause the binary to shrink, via the gravitational
Brownian Motion Ultimate players, Brown lost in the quarterfinals of every major tournament in the Spring, including Nationals. This was also the first time in four years that Brown lost Regionals as both Harper Alexander and Moses Rifkin were injured. After the disappointing 2001, 2002 was even worse for Brownian Motion. Having lost Callahan runner-up Moses Rifkin, Brown was a young class of talented players. The team began to play well in the Spring season, losing in the semis at the Stanford Invitational and winning sectionals. However, after a roster submission fiasco in the Northeast, the region had only one bid to Nationals
