The space that we're looking through is nine-dimensional. If you build a mathematical model, the amount of searching that we've done in 50 years is equivalent to scooping one 8-ounce glass out of the Earth's ocean, looking and seeing if you caught a fish.

We don't know how to identify intelligence over interstellar distances, so what we do instead is use technology for a proxy.
In the future, will our technologies help stabilise or planet and population, leading to a very long lifetime for us? Or will we destroy our world and its inhabitants, after only a brief appearance on the cosmic stage?
The story of humans is the story of ideas that shine light into dark corners.
