The Most Scientifically Realistic Sci-Fi Alien Species
Science fiction often explores the possibilities of what life could be like in distant parts of the cosmos. While many alien species portrayed in popular media and literature are more character-driven, some strive to be scientifically realistic. This article delves into the fascinating alien species that come close to scientific accuracy and showcases the efforts behind crafting these sci-fi beings.
The Beach Ball Alien from Dark Star
One of the most memorable, albeit less realistic, alien species in science fiction is the beach ball alien from the 1974 film Dark Star. Created by Dan O'Bannon, the beach ball alien is a simple, yet memorable creature. O'Bannon went on to become a significant figure in the science fiction community, contributing to other notable films such as Alien.
Barlowe's Guide to Extraterrestrials
For those interested in biologically plausible alien species, turn to Barlowe's Guide to Extraterrestrials. Alan Dean Foster and Tim Barlow collaborated on this book, which provides detailed illustrations and descriptions of scientifically viable alien forms. This resource offers a starting point for those seeking realistic alien species.
Star Trek and Star Wars: Costuming Considerations
Arguably, one of the main reasons why alien species in the Star Trek and Star Wars franchises are humanoids is economic. Specifically, producing costumes and makeup for alien characters can be resource-intensive. A notable example is the Horta in Star Trek, which was a guerilla in a rubber suit. However, the Horta's costume was created with considerable effort, making its inclusion in the show more plausible.
My Science Fiction Novel: Realistic Aliens
My own science fiction novel, which is nearing completion, features alien species with carefully considered scientific attributes. In this story, the Loh-yoan and the Khee-yoan are two such species.
The Loh-yoan: A Silicon-Based Oviparous Species
The Loh-yoan are described as silicon-based oviparous creatures with a fascinating array of physiological and genetic differences from humans. Their distinctive eyes are a prime example: the retinas of a shuttlecraft operator's eyes are described as glittering like opals, but interestingly, she lacks pupils. This is due to the vitreous humor inside her eyes being photochromic, turning dark in strong light. While the opalescence of their eyes may be a beloved trait among readers, the practical reasons behind this feature are rooted in scientific plausibility.
The Khee-yoan: Evolved in a Salty and Electric Environment
The Khee-yoan, native to a planet covered by a salty ocean and abounding in electricity, have evolved in a unique environment. Their physiology is both intriguing and plausible. Terrestrial crustacean-like in appearance, the Khee-yoan have radial symmetry and manganese-based blood, which not only makes it challenging to asphyxiate them but also positions their spoken language as a digital multiplexing mimic. One of the characters in the story is depicted wearing a yellow belt displaying chromoglyphic script used by the Loh-yoan, a unique form of written communication.
Bringing the Loh-yoan and Khee-yoan to Life
Portraying the Loh-yoan on screen would largely require fitting an actress with a costume, wig, and mask, making it relatively straightforward. In contrast, bringing the Khee-yoan to life would necessitate advanced CGI or sophisticated robotics due to their complex physiological features and the unique visual elements inherent to their species.
Conclusion
The realism of fictional aliens depends heavily on their human creators' knowledge of actual scientific principles. By drawing from credible biological, physiological, and ecological concepts, these species can become not only memorable but also scientifically plausible. Whether it's through illustrations in Barlowe's Guide to Extraterrestrials, the practical considerations in popular media, or carefully crafted stories, the quest for scientifically realistic alien species continues to captivate science fiction enthusiasts and creators alike.
