‘Future First’: Where Are All The Aliens?

Why haven't we seen signs of complex extraterrestrial life?

Technology is really a marvel. So often, as new technology comes out and allows us to do things that were thought impossible in the past, we hear the phrase “The future is now.” Popular Science and XPRIZE are teaming up to explore and explain technologies like these in a video series called Future First.

Episode four of Future First is titled “Where Are All The Aliens?” In it, we explore why there is a significant lack of evidence that complex extraterrestrial life exists, even though there is a high probability that it does. Helping to lead the discussion are NASA director Jason Crusan and sci-fi writer David Brin.
