The influence high mass stars have on our Universe is that they create and affect many other bodies in space. For example, when they explode, they create supernovas and eventually those supernovas create black holes. They also are very beautiful and powerful. A high mass star starts out in a nebula and is created by the matter that lies in the nebula. When the hydrogen gas is forced together due to gravity, the star begins to spin and reach extreme temperatures. It gets so hot that it begins nuclear fusion in the core. It is now a main sequence star and glows very brightly for millions of years until it is ready to start the next phase of its life.
In the next stage, the star runs out of hydrogen to convert to helium so it becomes unstable
