>In 2002, three decades after Hawking’s result, the physicists Roberto Emparan and Harvey Reall — now at the University of Barcelona and the University of Cambridge, respectively — found a highly symmetrical black hole solution to the Einstein equations in five dimensions (four of space plus one of time). Emparan and Reall called this object a “black ring” — a three-dimensional surface with the general contours of a doughnut.

A hypersphere, or a sphere in 5 dimensions, would render in our frame of reference as a Kerr (ring) black hole.

Unsure about those infinite configurations and their stability in a spacetime frame of reference. Most probably rapidly decay.
