    Today’s image is billed as a ring of black holes. As such, it presents a fairy ring of gravitational fantasies.

    The first fairy dances a fantasy of Redshift-is-Proportional-to-Distance, overlooking half a century of contrary evidence. That puts the ring far away. For the ring to appear as bright as it does, a second fairy must dance a pas de deux of Super Luminosity. To get that much energy from the feeble force of gravity, a third fairy must support the others with the Dance of Great Mass.

    Since the ring is constrained by the Assumption of Equivalence of Mass and Matter, a fourth fairy must squeeze in—and be squeezed to a supernatural density. She (or he, we can’t tell at these densities) can’t dance but can only quiver and quake. When the other fairies bump into her, she does emit X-rays. The ring is the result of the crowded stage and the bumping.

    Fairy rings and fantasy dances are entertaining, but when a theory requires this much supernaturalism, it would be wise to question assumptions. Astronomers no longer see what’s there but gaze with incurious enchantment upon artists’ impressions of obsolete hypotheses.
