As the expansion of the universe accelerates, every galaxy that now fills the night sky will pass beyond our visible horizon. Cosmology will no longer be an observational science because all we will be able to observe is our own galaxy. At that time, will we have to take the story of the Big Bang on faith?

Avi Loeb considered that distant future at an event to celebrate the 50th anniversary of the discovery of the Big Bang (via detection of the cosmic microwave background). Part of the Observatory Night lecture series at the Harvard-Smithsonian Center for Astrophysics.

The Harvard–Smithsonian Center for Astrophysics (CfA) is one of the largest and most diverse astrophysical institutions in the world,[citation needed] where scientists carry out a broad program of research in astronomy, astrophysics, earth and space sciences, and science education. The center’s mission is to advance knowledge and understanding of the universe through research and education in astronomy and astrophysics.
