Anyone who saw the blockbuster sci-fi film “Project Hail Mary” will remember Rocky, a creature unlike anything we’ve seen on Earth.
The five-legged alien is composed of a rock-like material, hence its nickname, and comes from a fictional planet where temperatures and a high-pressure ammonia-dominant atmosphere has driven evolution in a radically different direction (still, he’s a cool guy.)
The idea of such different yet conscious being is a fun thought experiment. And according to University of California philosophy professor Eric Schwitzgebel and University of Antwerp postdoctoral fellow Jeremy Pober, it may not be quite as far-fetched as it sounds.
In what can only be described as a vape cloud of a working paper, the pair examine the possibility of other consciousnesses that take on forms far beyond conventional imagination, arising from wildly different materials than those found on Earth. They argue that given the vastness of space, life could take dramatically different forms elsewhere.
“Suppose your best guess estimate is that, on Earth, consciousness is present in all vertebrates, plus cephalopods and some insects,” they wrote. “And suppose that your best guess estimate is that on average each galaxy contains a million planets where species of approximately that level of behavioral sophistication eventually evolve (even if technological civilizations rarely arise).”
“The observable universe would then host, over its lifetime, a quintillion qualifying planets,” they added. “With that many draws from the lottery, some of these life forms will be strange indeed.”
The team examined a fundamental concept in philosophy called “substrate flexibility,” which describes how the same materials can have multiple different properties. For instance, a cup can be made from a litany of different materials and still successfully contain liquid.
In their paper, Schwitzgebel and Pober argue consciousness could also be “substrate flexible,” meaning that it doesn’t have to be made out of conventional carbon-based flesh and blood.
“The universe may contain minds stranger than we can imagine,” said Schwitzgebel in a statement.
