[Rockhounds] Number of contactable alien civilisations estimated at 36

[Axel Emmermann]

I strongly disagree, Bryan. 
Hogwash is wanting to put boots on the moon before 2024, or putting people on Mars any time soon. We may want to and we may try, but we don't have the technology yet. The first ones to brave the void will die... Inevitably! Something modest and simple like engineering a reusable spacecraft for hopping about in Earth's immediate vicinity resulted in at least 14 dead astronauts.  
If you really want to see hogwash then look at the Drake equation. 
If you really, really, REALLY want to see something of truly Olympic stupidity then take a look at the Kardashev scale.
Nevertheless, famous scientists like Carl Sagan spoke highly about both.

Cheers
Axel

What hogwash. Imagine a race of intelligent apes living on an island in the middle of a vast ocean with no other close islands. They are the only critters on the island which is covered with banana trees. One of them proceeds to calculate that there are 37 other intelligent critter species living on other unseen islands based on no data whatsoever.

There you have it.
