Universe Likely Has Many Extinct Civilizations: Study

A new paper in Astrobiology suggests there could be a way to simplify the equation, based on the observations of exoplanets that we have made since the first one was discovered in the 1990s. While the result is depressing — life was plentiful, but is likely extinct — it does have applications to help us extend our own civilization, the researchers said. The research was led by Adam Frank, a physics and astronomer professor at the University of Rochester.


“Our results imply that our evolution has not been unique and has probably happened many times before,” Frank said. “The other cases are likely to include many energy-intensive civilizations dealing with their feedback onto their planets as their civilizations grow. That means we can begin exploring the problem using simulations to get a sense of what leads to long lived civilizations and what doesn’t.” (discovery)
