Alien Intelligence and Plant Intelligence

 As NPR reports, planets are being discovered that might support life.  These new and exciting celestial spheres are more-or-less suitable for the emergence of life: the temperature, gravity, and elemental make-up of such planets can create selection pressures that range the gamut from mild to pretty-much-inhospitable.  One such discovery is especially noteworthy: Kepler 22-B (named after the telescope) is in the ‘goldilocks’ zone.  In this zone, the size of the planet and its proximity to its star create the right sort of conditions to support flowing water.

The BBC (picked up by Slate) go on to make the link between the discovery of such planets and astral systems, and SETI, the Search for Extra Terrestrial Intelligence.  With the discovery of more and more of these potentially-hospitable earth-twins, SETI gains a more plausible target to turn its arrays.  With the discovery of more and more of such planets, it is more likely (though I am hesitant to use this term here) that we may discover intelligent life.  Another variable in the Drake Equation starts its climb up in the cardinal numbers.

But wait! What is intelligent life?  The ability to broadcast galactic radio-waves?  Drake, at least, keeps that a separate variable, a tier that only a select group of intelligent critters will ever reach.  But that really seems to operationalize our search for intelligent life.  What if, being impatient, we send a probe (‘Make it so Number One’, etc.) to Kepler 22-B and discover strange, barely congealed bioluminescent areas – would we be right in attributing it with intelligence?  Might our current conceptions of it be too broad? – too exclusive?

What if Mars Attacks?

Whenever a conversation flairs up with my friends about space, planets other than our own and the possibility intelligent life elsewhere in the galaxy, I am always afraid that someone will over hear our conversation and think we are inner city equivalents of a stressed dairy farmer from Iowa who claims to have been abducted and experimented on by aliens. Just to be safe I tend to keep my voice down during such conversations.

However over recent years since the observation of the first planet orbiting a star other than our own (extrasolar planets Continue reading “What if Mars Attacks?”
