Or anything else.
Seems like standard operating procedure for Greer.
And then he claims that the NSA or some other agency is 'jamming' the signals.
And then he says that the signals are 'increasing in frequency'. So aliens from billions of light years away, sent out radio transmission from their homeplanet, which took billions of years to reach earth, and then 'increase in frequency' over a time scale of what, a few years?
Nonsense. Any putative aliens wouldn't even know about earth, let alone that, at this exact moment in time, there was intelligent life on it, AND that it was specficially monitoring space for intelligent signals. It doesn't make sense to suggest that they sent out a signal that rapidly increases in frequency, and that we just happened to be looking for signals in the first place.
I think that this shows the Greer might not even understand what SETI is. Its not looking for a new signal, or a 'communicative' signal (which is what he calls it).
Its scientists realizing that man-made radio transmissions will extend far, far, out into space. And that if there was an intelligent, technological civilization somewhere else, their signals would've extended out into space, just like mans. SO if we look for such signals, we might find that we're awash with it.
NOT that we'll start looking, someone will say 'hey look, the humans are ready' and then start sending us a signal, like a telephone call or something.
amn you are entertaining.
