Quote:I am on the side of the scale being the issue...
Quote:The Drake equation is an attempt to put a scientific veneer on what is really a SWAG (silly wild-a$$ed guess).
Quote:We agree we aren't hearing (do not currently possess) information/signals/whatever indicating the presence of extra-terrestrial sentient life?
Quote:1. We aren't listening correctly (i.e. at an inferior technological level or level of inferior political willingness)
2. The geometries of scale and limits of physical reality are making any contact there might be difficult.
3. We're alone.
Quote: I heard that the primary feature on the unseen side of the moon is some huge multi-ring crater that looks like an eyeball. It has been suggested, if this had been the side presenting itself facing in our direction of view, this would have had tremendous ramifications for everything from our religions to mythology to inhibitions or inducements to scientific investigation.
Quote:..at a gut level, would you be willing to say which of the explanations you feel is most correct in explaining the silence?

Quote:Marco,What would it take?What would it take in terms of political will (i.e. the willingness to direct a portion of the nation's/world's wealth)?What would it take in terms of what type of financial investment?And finally, what would it take in terms of redirecting scientist preparation, and research funding approvals?I believe not long ago, most funding for SETI was cancelled. Therefore, practically speaking, I think this is a very relevant question.Otto
I simply do not know enough science or politics to verify if (1) 7 billion is sustainable, (2) the trend rates for the 7 billion is going in what direction and predicted to end at what point, (3) what the melting of the polar cap indicates in terms of natural cycles, human influence, and most important, future climate trends.
Quote:what polar ice cap???
Quote:how long ago did the first "real" thinking and reasoning humans appear; I mean humans that had a basic verbal language (beyond the grunts) to speak to one another?
Quote:That's the timeline I've always heard and read about, 50-60,000 years. Now it just baffles me that it has taken humans that long to say, put a man on the Moon.
