Kepler ultimately concluded that angels pushed the planets around the Sun True False A vortex would concentrate solids in the center of the vortex. True False Save Centrifugal force pulls inward like gravity. True False Disks stretch far out into space because of angular momentum transfer from particles falling into the disk from the surrounding cloud. True False Circumstellar disks have gravity that draws particles that are near to the disk into the disk. True False Save Scientists think that the Kuiper Belt is probably composed of comets that were thrown out of our Solar System by large planets. True False Since we are within the Milky Way, it looks like a fuzzy straight line at night. True False The large mass at the center of the Milky Way is a black hole.

True False The Orion Nebula is a stellar nursery.
