Scientists using NASA's Swift satellite say they have found newborn black holes, just seconds old, in a confused state of existence. The holes are consuming material falling into them while somehow propelling other material away at great speeds.

Many astronomers believe supermassive black holes may lie at the center of these galaxies and power their explosive energy output. Tell me about AGN! Tell me more about AGN! angstrom A unit of length equal to 0.00000001 centimeters. This may also be written as 1 x 10 cm (see scientific notation angular momentum A quantity obtained by multiplying the mass of an orbiting body by its velocity and the radius of its orbit. According to the conservation laws of physics, the angular momentum of any orbiting body must remain constant at all points in the orbit, i.e., it cannot be created or destroyed. If the orbit is elliptical the radius will vary. Since the mass is constant, the velocity changes. Thus planets in elliptical orbits travel faster at perihelion and more slowly at aphelion . A spinning body also possesses spin angular momentum.
