Universe Expansion

This article talks about a topic that we discussed in class a while back: expansion of the universe. It begins by stating that expansion is a known phenomenon but research in the force, called dark energy, that causes it has only been recently studied. The article discusses other topics we talked about in class. For example, how looking into space is like looking back in time. The article also discusses how dark energy came to be a force. This is a very interesting read that relates back to topics discussed in class.

Dark energy is a very important concept behind string theory, it would certainly be interesting to find out its ultimate role in the heat death of the universe.
