For example Rene Heller, an astrophysicist at the Max Planck Institute for Solar System Research in Germany, recently of McMaster University, has proposed a strategy in line with Cabrol’s interdisciplinary thinking. The positive responses have generated the most excitement. This advertisement has not loaded yet, but your article continues below. To be sure, this ‘gut feeling’ extends outside evolutionary circles. The believers think it too incredible to imagine humans as unique or exceptional in such a vast universe. Its motivations are too deeply grounded in evolutionary ideology. They conclude from this that we are probably unique in the universe.Īn editorial by the Discovery Institute on Cabrol’s idea, for example, compares SETI researchers to cultish fanatics searching for ghosts, who “refuse to take non-detection as an answer … Despite continued failures, SETI is unlikely to cave anytime soon. One criticism has come from intelligent design theorists, who believe humans were created supernaturally, not by natural physical and evolutionary processes. She said the response has been enthusiastic.
Her solution is to take “a step upstream,” to broaden the perspective on what it might mean for intelligent life to have arisen somewhere else, and to unite the various scientific disciplines that might contribute, from mathematics and evolution to neuroscience and geology. Article content Handout/The SETI Institute “You don’t know exactly what you are looking for, or even if you found something, because you cannot recognize it,” she said. She described SETI’s current main strategy of looking for non-natural patterns in electromagnetic signals from other Earth-like planets as a “shot in the dark.” To that end, she described the tactical change she wants to make to the basic approach of research at SETI, which applies scientific rigour to a question - the possibility of life on other planets - that is more commonly associated with sweaty conspiracy theorists and flaky fantasists.
“To find aliens, we must become the aliens,” she said.
“But we should not stay constrained or confined to that.” This is where we had to start,” said Cabrol, an astrobiologist and planetary geologist with a background in environmental science and the development of Mars rovers. Wells did at the turn of the 20th century, as quaint foreigners, either friendly or threatening, but fundamentally similar. Article content NASAĭespite a century of major scientific progress in everything from biology and evolution to physics and planet formation, we still imagine extraterrestrial life forms as H.G.
The problem, as Cabrol describes it in a provocative new research paper, is that human scientists have only ever looked for other versions of themselves.īy scanning the heavens for the same sort of messages we ourselves sent out in the 1970s - from the Arecibo radio transmission with encoded details of arithmetic and chemistry to the engraved plaques launched on Pioneer with rudimentary sketches of a man and woman, and the Voyager golden record with music by Mozart and Chuck Berry - we have, basically, been searching blind. But it is also revealing of a deep philosophical problem in the search for extraterrestrial intelligence, an all-or-nothing scientific gamble that is now at a crisis point. Just as the wealthy American polymath astronomer Percival Lowell did not actually see canals on Mars in 1906, so too is this latest bit of Martian clickbait a figment of a rich human imagination, reflecting our desire to find patterns in chaos. This was just dirt shaped by wind, as NASA itself eventually conceded. If only contact with aliens, if they exist, were so simple.
