As matter is pulled toward a rotating black hole, it reaches an area where all must spin in roughly the same direction. NASA astrophysicist Jeremy Schnittman has discovered certain orbits where a form of dark matter called Weakly Interacting Massive Particles (WIMPS) is mostly likely to collide, creating a burst of gamma rays, and thus revealing itself.
Dr. Schnittman finds poetry in the notion that two invisible entities could interact to shed light on one another.
