HEIDELBERG, Germany — If it’s not as dead as a doornail, the gravitational monster at the Milky Way’s center is clearly lethargic. The galaxy’s supermassive black hole barely radiates, and certainly doesn’t hurl jets of material into space — signs that it has been on a starvation diet.

And a new study suggests that the central black hole barely spins, either.

Black hole spin doctors Avery Broderick of the Canadian Institute for Theoretical Astrophysics in Toronto and his colleagues, includ...
