Dense regions reach a maximum size and then fall back into a bound object like a cluster of galaxies. Once the cluster is formed, its physical size remains essentially constant. The space-time diagram below . shows a dense region in blue on the left. ... The galaxies in the blue region are accelerating more just because the region is denser and therefore has higher gravitational forces. ... Tutorial : Part 1 | Part 2 | ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...
