View Full Version : Astronomy Without A Telescope Bringing the Planetology Home

We keep finding all these exoplanets. Our detection methods still only pick out the bigger ones, but we're getting better at this all the time. One day in the not-too-distant future it is conceivable that we will find one with a surface gravity in the 1G range – orbiting its star in, what we anthropomorphically [...]

The probe, and also the initial detection sensor recording the morse code signal probably needs checking for some fault which roughly equates with acoustic feedback. Hari Seldon in his second paper on psychohistory, entitled,"Problems With Equating Calculations Simultaneously With Local History on a Galactic Scale", noted that most theoretical mathematical projections for the future would endlessly repeat their source assumptions unless an additional infinite variable was introduced, later known as the 'Prime Radiant's Blessing'. This led to his third paper, "I Think I've Finally Cracked It Big Time", which caused immediate offence with the Galactic Emperor, who felt a little diminished in importance as a result of Seldon's breakthrough. Arrangements were then made to quietly get rid of Seldon and pyshohistory, while all probes in the Galactic Empire were upgraded to fix the problem of acoustic feedback.

It would be very boring if an interstellar probe from Earth will arive at a planet inhabited by some folks playing around with more or less the problems we have. Esspecially the carbon-dioxide-problem cannot be ubiquitary, because it depends on the efficiency of photosynthesis which is only around three percent on Earth. If You have "better" plants, carbon dioxide is better removed from atmosphere and there is no problem with.

If a space probe is able to look for life autonomously is an interesting question, because there are some hints what "planetary life" may be, but really nothing is clear. Remote sensing by spectroscopic means will give some results, but chemistry is complex and life is also and alien life may base on other principles than our ife on Earth. It would have to land, take samples and shake hands or tentacles.

Artificial intelligence is a fascinating topic. But what is intelligence? Useful reactions of a robot can be reduced on simple decisions, but there is a very large catalogue full of them necessary to do something intelligent. Will simulated AI give real AI at a certain level? AI should be not confused with human or ethical behaviour or other types of psychological factors.
