New Method Developed To Weigh, Resolve Distant Black Holes

A new, simple method to learn about black holes up to eight billion light years away -- thousands of times farther away than black holes can be measured today -- has been developed. Astronomers and physicists have concluded that the larger the black hole at the center of a spiral galaxy, the tighter the galaxy's arms wrap around itself. If correct, the simple relationship would give researchers an easy way to learn about black holes.
