UH Astronomer Finds Giant Galaxy Hosting the Most Distant Supermassive Black Hole
Institute for Astronomy - University of Hawaii - September 4, 2009

University of Hawaii astronomer Tomotsugu Goto and colleagues have discovered a giant galaxy surrounding the most distant black hole ever found. The galaxy, which is 12.8 billion light-years from Earth, is as large as the Milky Way galaxy and harbors a supermassive black hole that contains at least a billion times as much matter as does our Sun.

"It is surprising that such a giant galaxy existed when the universe was only one-sixteenth of its present age, and that it hosted a black hole one billion times more massive than the Sun," Goto said. "The galaxy and black hole must have formed very rapidly in the early universe."

A billion solar mass black hole has a black hole Schwarzschild radius of ~20 AU

A descending astronaut should be able to approach within ~1 AU of the
black hole singularity before feeling much discomfort from tidal forces.

G'day Bystander

Thanks for that link

Hello neufer
As for BH a singularity is only in theory and not a fact.

Unless you define a singularity without a finite point.
