When the polis Carter-Zimmermann reaches the planet Orpheus in orbit around the star Vega, alien life is found in its oceans. An attempt for first contact fails, but micro probes sent down reveal their structure to be that of carpets made out of 20,000 unique polysaccarides. Closer inspection reveals, that the carpets are growing by adding new lines of polysaccarides and that they are resembling Wang tiles. According to a theorem by Hao Wang, any Turing machine can be described this way with new lines corresponding to new iterations of the calculation. A Fourier transformation uncovers, that the carpets are simulating a sixteen-dimensional universe and squid-like aliens living within. Even though contacting them is impossible, the characters reflect that them waiting on aliens to communicate with and seeing these ones as isolated also applies the exact other way around.[3]
Reception
Reviews
Rich Horton, writing in the Locus Magazine, compares Egan's other short story "3-adica" to "Wang's Carpets" and calls the latter "one of his very best".[4]
Greg Johnson, writing for the SF Site, states that "the references to 'Gleisner body' and 'physiological model', in the context of Egan's universe, are very revealing" and that "Egan's technical and scientific language works to a double purpose," since "it contributes to the story's worldbuilding and adds to characterization."[5]
Awards
The short story was nominated for the Aurealis Award for Best Science Fiction Short Story in 1995. Egan's other short stories "Mister Volition" and "Luminous" were also nominated with the latter winning the award that year.[6]
