What Was the WOW Signal?
Comments (1)
We can't say we have looked hard at all for SETI signals. No analysis have ever shown that the signal originated near Earth which makes it the only viable candidate we have for a signal from another civilization. Also, with 98% of the sky not having been surveyed we haven't even tried. There are 5 degrees of freedom here. Big Ear hit the big one by being lucky. The spot where the signal appears to original is largely empty. On the one hand you might conclude this proves it was a false signal, or perhaps a glitch in the processing by Big Ear's computers. I was in this boat until I played out several game theory rounds and discovered that the smartest strategy is to negotiate contact off of your home world. Now, being able to create a 2.2 GW signal in interstellar space takes technology we don't have. However we can imagine it. It's not impossible. If that is the case then perhaps the Wow! signal came from a probe or a reflector. In which case it's up to us to scan wider, more constantly and everywhere. To do this I suggest a crowdsourced project where people build small, purpose built radio telescopes and run them. Get enough people and enough data and let SETI@home crunch the numbers. It would greatly increase the coverage of space, produce useful radio telescope science, and be a neat project. It's easy to build one and several people have created web pages and pdf documents dedicated to it.
