comment What would a rotating black-hole look like to a “geo-stationary” observer orbiting the black hole
GRS 1915 has a mass of ~15 Msun, so with a near-maximal spin, the horizon has a radius of 15*1.5 km = 22.5 km, so the orbital velocity is actually "only" about 1/2 c.

comment Would the time dilation from being in low orbit around a black hole delay/slow the effects of quantum tunneling?
on a much shorter time, the gravitational wave losses would cause the rock to spiral into the black hole.
