One could imagine that a well-developed ETI might invest heavily in such a system, so that might be the most detectable signal it produces.Earth-crossing – what a lovely euphemism for dinosaur-extinction-level-impacts.

In fact, if we consider the Earth’s example, the most distinctive emissions come from early-warning radar systems scanning the horizons for incoming missiles. Woody Sullivan did a study of this in Science years ago, including measurements of the leakage signal reflected from the moon.If it’s any consolation, though, such radars provide a lot more information about the home planet (for example, its rotation rate) than the less directional radio and TV signals.

There is a ‘Berkeley’ school of music (in Boston). Here in Minnesota, I live a few blocks from Northwestern. When I was in Massachusetts, just south of town was “SMU” (Southeastern Mass U).Doug: Five bucks says I’m right.

What are the chances that life evolved on other planets? 100%.

I’d quibble with that Greg. As much as I agree there is always the possibility that it hasn’t happened yet. 🙂
