In reply to the discussion: Bill Nye's Answer to the Fermi Paradox [View all]PoindexterOglethorpe
(25,816 posts)32. I think we're headed for a population crash much, much sooner.
The current population, some 7.6 billion people, is totally unsustainable. Even without climate change (or even if the climate change is not at all connected to man-made factors) there are too many people using too many natural resources. Already the scarcity of water in various places, the life-threatening pollution in cities in China and India, the possibility of famine of some sort of serious crop failures occur, all these make me very uneasy.
If we are very, very lucky, there will be a decline that is not a crash. But it's probably already too late for a crash not to happen somewhere down the road, whether sooner as I think, or later as you do.

Not as simple as just tuning to the specific frequency, but to be able to decode the information.

The first problem is that this is not so much a paradox as a question...

Tight beam communications, like lasers or masers, are more efficient. Broadcast is wasteful.

That doesn't seem to me to be a paradox at all considering the vastness and distances of space.
