As long as it has existed as a genre, there has been a notable relationship between science fiction and science fact. Since our awareness of the Universe and everything in it has changed with time, so have depictions and representations in popular culture. This includes everything from space exploration and extraterrestrial life to extraterrestrial environments. As scientists keep pushing the boundaries of what is known about the cosmos, their discoveries are being related to the public in film, television, print, and other media. <\/p>\n
In the field of science communication, however, there is a certain hesitancy to use science fiction materials as an educational tool. In a recent paper that appeared in the Journal of Science Communication<\/em> (JCOM), a team from the St Andrews Centre for Exoplanet Science and the Space Research Institute (IWF) of the Austrian Academy of Sciences focused on a specific area of scientific study \u2013 extrasolar planets. After analyzing a multimedia body of science fiction works produced since the first confirmed exoplanet discovery, they found that depictions have become more realistic over time. <\/p>\n <\/p>\n The team was led by Emma Johanna Puranen, a St Leonard\u2019s Interdisciplinary Doctoral Scholar at the University of St Andrews with degrees in astronomy and history. She was joined by Emily Finer, a senior lecturer at the University of St Andrews and co-director of the interdisciplinary St Andrews Centre for Exoplanet Science; V Anne Smith, a senior lecturer in the School of Biology and associate dean curriculum for the faculty of Science at the University of St Andrews, and the IWF Director Christiane Helling. Together, they conducted a Bayesian network analysis of exoplanet representations before and after the discovery of actual exoplanets.<\/p>\n The interrelationship between scientific discovery and their portrayal in science fiction is certainly well-known. However, that does not mean that the phenomenon is well-understood, and attempts to study it are still in their infancy. As part of her thesis work, Puranen and her colleagues sought to address this by documenting a key example. As she explained to Universe Today via email, it is difficult to pin down when the tradition of science informing science fiction began since its roots go rather deep:<\/p>\n \u201cI would say it consciously goes back to the time in the early 20th<\/sup>\u00a0century when the genre as we know it today was being defined. But in practice, it goes back further. Science and SF have always influenced each other. Shelley, for example, was inspired to write Frankenstein by what she read of contemporary experiments on galvanism [the therapeutic use of direct electric current].\u201d <\/p>\n<\/blockquote>\n In addition, Puranen and her colleagues were motivated by a pervasive trend regarding science communication. This is the hesitancy on behalf of many communicators to avoid using science fiction as an educational tool, perhaps owing to a lack of clarity. \u201cI think this happens because what is fact and what is fiction within SF is not clearly marked,\u201d Puranen added. \u201cOne of the biggest challenges in science education already is addressing misconceptions about science that students come into the classroom with, so I can understand the hesitancy.\u201d<\/p>\n For their study, she and her team began by looking at exoplanet representations since 1995, when the first exoplanet was discovered. This was the hot Hupiter 51 Pegasi b (Dimidium), a gas giant that orbits very closely to its parent star, located about 50 light-years away. The focus on exoplanets was key because of the incredible growth this field of study has experienced in recent years, ever since the launch of the Kepler<\/em> mission (2009-2018). To date, 5,595 exoplanets have been confirmed in 4,160 systems, while another 10,146 candidates are awaiting confirmation). <\/p>\n Puranen and her teammates consulted 142 science fiction works, including novels, films, television programs, podcasts, and video games. While some were recommended by team members (based on personal experience), others came from a crowd-sourced Google form, from which the team fact-checked entries. These were subjected to Bayesian network analysis, a quantitative tool traditionally used to illustrate probabilities based on certain variables \u2013 in this case, exoplanet discoveries. The parameters they focused on included characteristics like atmosphere, presence of native life, and so on.<\/p>\n Their analysis revealed something very interesting: since 1995, the portrayal of exoplanets has undergone a significant shift. Essentially, with the growing discovery of exoplanets, the way in which they have been represented in science fiction has become less Earth-like. Said Puranen:<\/p>\n \u201cOne thing that became pretty clear is that lots of SF exoplanets are pretty Earth-like. This makes sense, as SF is written by humans, for humans, usually about humans. Still, the Bayesian network showed that since the discovery of real exoplanets, both fictional exoplanets with established non-native human populations living there, and fictional exoplanets with intelligent native life, are becoming less likely. <\/p>\n \u201cBoth these traits are part of this positive cluster of Earth-like traits, so the fact that their negative links are the mediation between that cluster and the variable of before or after real exoplanet discovery is interesting. It could indicate a few things\u2014it could be that writers are reading about discoveries of all these wildly un-Earth-like planets in real life and are writing less habitable worlds in their fiction, or it could be that they\u2019re focusing more on worlds with unintelligent ecosystems. Either way, it\u2019s definitely showing that SF worldbuilding responds to scientific discovery.\u201d<\/p>\n<\/blockquote>\n According to Puranen, this trend demonstrates how science fiction responds to scientific discovery. Past examples also demonstrate this close relationship. For example, how Mars has been portrayed in popular media has closely mirrored what scientists knew about the planet at the time. Prior to the Space Age, astronomical observations during the 19th century revealed several similarities between Mars and Earth, such as polar ice caps and contrasts in surface albedo (which was mistaken for land masses and oceans). <\/p>\n Along with linear fat were mistaken for canals and infrastructure, these observations led to the popular myth of a Martian civilization. Examples of this can be found in everything from The War of the Worlds<\/em> (1898) and the Barsoon Series <\/em>(1917-1948) to The Martian Chronicles<\/em> (1950). But once robotic missions like Soviet Mars <\/em>and NASA Mariner <\/em>probes, and NASA\u2019s Viking <\/em>missions revealed the harsh nature of the Martian landscape, these myths were dispelled. After that, science fiction books focused on how Mars might someday become a second home for humanity, as exemplified by Kim Stanley Robinson\u2019s Mars Trilogy<\/em>. <\/p>\n The renewed interest in the human exploration century has also found representation in SF, such as Andy Weir\u2019s The Martian.<\/em> This interrelationship makes SF a potentially useful tool for illustrating the history of science and our evolving understanding of the Universe. As Puranen summarized, the study she and her team conducted could help this process by clarifying the nature of SF and how it has historically portrayed scientific discoveries in an accurate way:<\/p>\n \u201cEvidencing that SF responds to scientific discovery is a first step towards incorporating it into curricula\u2014a lot more work needs to be done, particularly I think more work in analyzing the scientific content of SF. There are people out there using SF texts in their science classrooms, mostly on a case-by-case basis\u2014I think what our study allows people to do is place works within a broader context of the genre. <\/p>\n \u201cThe Bayesian network can help people compare how various texts address various scientific contexts, how SF reflects the contemporary science of the time in which it was written, and tailor their use of SF in the classroom. Personally, I think it has the potential to be an excellent tool to introduce concepts and inspire readers to want to learn more.\u201d<\/p>\n<\/blockquote>\n Further Reading: Space Daily<\/em>, <\/em>Journal of Science Communication<\/em><\/p>\n\n
