In the vast universe of science fiction, the “science” aspect can sometimes get overshadowed by imaginative storytelling. Numerous sci-fi series often prioritize elaborate world-building and fantastical elements over realistic scientific principles. While this approach can yield entertaining content, sci-fi enthusiasts occasionally seek shows that incorporate genuine scientific accuracy, providing a refreshing blend of fact and fiction.
Fortunately, the realm of television has birthed numerous exceptional sci-fi series that honor the “sci” in science fiction. Spanning space operas, tales of cloning, and gripping post-apocalyptic narratives, these scientifically precise shows demonstrate that the genre can maintain a strong connection to reality. This list ranks ten of the most scientifically accurate sci-fi shows, highlighting their impressive adherence to science and technology.

‘Firefly’ (2002–2003)
Created by Joss Whedon
Considered one of the most iconic sci-fi cult classics in television history, Firefly stands out as one of the best sci-fi shows of the 2000s. Despite its unfortunate cancellation after just one season, followed by a movie conclusion that failed to capture the original’s magic, the dedicated cult following it cultivated over the years remains impressively steadfast.
Fans of sci-fi have a myriad of reasons to adore this space Western, and its moderate grounding in actual science is a significant factor. While certain elements of the show stray into the realm of fantasy, many aspects feel refreshingly realistic. For example, the portrayal of space travel is depicted as challenging and chaotic, with the absence of sound in the vacuum of space being accurately represented. Moreover, the gadgets featured in the series exhibit a design sensibility that aligns with reality.

‘Defying Gravity’ (2009)
Created by James D. Parriott
While it may share its name with a popular musical theater song, Defying Gravity also stands out as one of the most underrated sci-fi shows from the 2000s. This series chronicles the lives of eight astronauts aboard an international spacecraft on an ambitious mission through the Solar System, all while the world observes from billions of kilometers away. Misguidedly marketed as Grey’s Anatomy in space, this series is a unique blend of character-driven storytelling and sci-fi elements, leading to its unfortunate cancellation after just one season.
The emphasis of the show was not on the grandiose sci-fi tropes that some genre fans might anticipate. Instead, it focused heavily on character development and the dynamics between the astronauts. This character-centric approach allows for a more authentic representation of space travel, even if it occasionally dips into speculative territory.

‘The Last of Us’ (2023–)
Created by Neil Druckmann and Craig Mazin
The critically acclaimed The Last of Us, a product of the renowned video game studio Naughty Dog, has garnered immense popularity, making it one of the most celebrated video games in history. When it was revealed that HBO was adapting this masterpiece into a television show, expectations soared. Despite some divisive opinions surrounding its second season, the series has largely succeeded in meeting those expectations, achieving an impressive IMDb rating of 8.6, placing it among the highest-rated shows on the platform.
Adapting a game to the screen can prove challenging, but this series defies the common trend of unsuccessful adaptations. The original game was already cinematic, yet the showrunners enhanced the narrative’s emotional depth, making it resonate even more profoundly than fans could have predicted. They thoughtfully altered certain aspects of the game, particularly concerning the lore around the infected—zombie-like creatures driven by fungal pathogens. While a real-life scenario of such an infection ravaging humanity remains improbable, the show showcases a well-researched connection to the science of fungi, pathogens, and global pandemics, which is commendable and appreciated by many.

‘For All Mankind’ (2019–)
Created by Ronald D. Moore, Ben Nedivi, and Matt Wolpert
For All Mankind transports viewers to an alternative reality where the events surrounding the space race take a different trajectory. If this version of reality mirrors our own, then this Apple TV+ original is undoubtedly one of the genre’s most underrated offerings. The series captivates audiences with its attention-grabbing narrative and exceptional production quality, marking it as one of the streaming platform’s finest achievements.
This remarkable series has garnered acclaim for its commitment to scientific and technological realism. Although it has gradually leaned more into the fictional aspects of science fiction, it still stands out as a show that maintains a strong grasp on realistic science. The physics, depiction of space exploration, and portrayal of NASA are all grounded in real-life science and history, while the series is not shy about taking creative liberties.

‘Star Cops’ (1987)
Created by Chris Boucher
Another underappreciated gem in the sci-fi genre, the BBC classic Star Cops explores the missions of the International Space Police Force set in 2027. This unique force comprises officers from multiple nations, tasked with enforcing the law across the burgeoning colonies of the Solar System.
Created by a writer with prior experience on Doctor Who, Star Cops is hailed as one of the best British sci-fi series ever produced. Unfortunately, its failure to gain a significant audience led to its cancellation after just one season. However, over time, it has been recognized for its refreshingly realistic portrayal of the challenges in space exploration, showcasing aspects that the genre often overlooks.

Orphan Black is renowned not only for its gripping narrative but also for its realistic portrayal of science fiction.

As advances in technology continue to emerge, the show’s depiction of these themes has aged remarkably well, resonating with audiences even today.
