Exobiology
Project Seti has looked in the wrong place for ET life. It turns out they have been looking at us.
The cunning part is how they get their results back to Alpha Centauri, or the Andromeda galaxy.
Why the secrecy? Remember that when the first pulsar was discovered, and was thought to be an ET clock signal, the facts were kept secret for six months. The lamest excuses were given when things were published.
