Dark Energy and the Expanding Universe

By George R. Steber    View In Digital Edition  

Time for a little weird science! Concepts such as energy density and negative pressure as they relate to our expanding universe are difficult for most of us to understand since we don’t see them in our daily lives.

In this article, we’ll explore these ideas and analyze an electrical model with similar properties that is constructed with some copper plates and an electrometer. Comparing this model to the cosmological model of our universe should help us understand these concepts and emerging theories of the cosmos. Hopefully, in the process, we’ll learn more about how our fantastic universe works.
