... all matter and energy in their path, even light itself. In recent years, however, there has been recognition that black holes seem to have some role in galaxy formation. For example, there's generally a supermassive black hole at the center most galaxies and recent research has shown that black holes may cause gamma ray bursts as they devour stars.
In fact, the ...
