Dang...roadkill on the information superhighway!
"High-frequency QPOs are likely from matter racing around the black hole, glowing like lightbulbs on a merry-go-round," said Homan. "Of course, matter is moving much faster around a black hole than on any amusement park attraction. We see frequencies of hundreds of hertz, or hundreds of revolutions of the disk per second. That's quite a ride."
Hundreds of revolutions of the disk per second. When you figure that the disk probably has a diameter of several tens (or perhaps even hundreds) of miles, the imagination starts to struggle.
Is that a comment on this...?

Near the black hole, gravity is rather intense
Now THIS is a gift for understatement :)
