The theory of cosmic evolution is a relatively new addition to the field of cosmology, and attempts to answer the questions of who we are, where we are, and how we came to exist, among others, by taking the long view — from the big bang, to the present day.
Here’s another definition for you: “Cosmic evolution is the study of the many varied changes in the assembly and composition of energy, matter and life in the thinning and cooling Universe.”
This explanation comes from Eric Chaisson, a vigorous champion of the cosmic evolutionary theory. He’s an astrophysicist at the Harvard-Smithsonian Center for Astrophysics, and a lecturer at Harvard Extension School, who is also the subject of this Faculty Insight interview, conducted by ThoughtCast’s Jenny Attiyeh.
And while it might leave more questions asked than answered, we hope it will give you the chance to stick your toe into deep astrophysic waters, and feel the tug of the cosmic tide…
