In Star Trek's imagined history, inventor Zefram Cochrane achieves faster-than-light travel in 2063—and helps usher in peace on Earth.
Our first alien visitors, the Vulcans, will reveal themselves. Humanity will eliminate poverty and war, found Starfleet and the Federation of Planets—essentially a spacefaring United Nations—and work with hundreds of alien civilizations to explore the universe and, as Captain Jean-Luc Picard puts it, "better ourselves and the rest of humanity."
"A dream that became a reality and spread throughout the stars," as Captain James T. Kirk calls it, Starfleet mirrors Star Trek itself. Across more than a thousand episodes and 13 television series, the franchise has inspired scientists, engineers, and generations of viewers to imagine technologies and futures that did not yet exist.
The characters also modeled ways of confronting real-world ethical questions. "Star Trek is built around examining our present and our history through a futuristic lens, which is what makes it different from most other sci-fi series," said David Proctor of the Department of History, who taught the University College course History Through Star Trek this summer—and wore a Starfleet insignia on his lapel for an interview.

Sixty years ago, Star Trek asked viewers to imagine something fairly audacious: Russian, Japanese and American officers serving side by side on starships, in a future where humanity had survived war and prejudice well enough to turn outward.
Today, the franchise has branched into action, romance, music, comedy and animation. Starfleet officers are younger, more diverse and more flawed. In the real world, meanwhile, we wield more powerful technologies and face a new set of moral questions and existential threats, and Star Trek's portrait of our times has grown darker.
But scientists, historians, and students at Tufts are still using that fictional future to think about the real one. Molly Twombly, a graduate student in the Kounaves Planetary Analysis & Astrobiology Lab who studies life on other worlds, included Starfleet's Prime Directive this past spring in her Experimental College course The Science in Sci-Fi and Popular Media: Molecules, Movies, and Other Worlds.
"Sci-fi does a great job of showing that through this exploration, things can be exponentially better than they are now. And I think that it's always propelling us forward," Twombly said. "That's just what humans do—we look forward. We're explorers, we're curious, and we want positive growth wherever it takes us."
A safe space
Imagined futures have long offered a container for the tensions and concerns of their times. "Science fiction is a way for us humans to tackle these moral and ethical and scientific dilemmas in a controlled, closed environment where it's okay to make mistakes," Twombly said.
Unable to address conflicts such as World War II, the Vietnam War and the Cold War directly, The Original Series often explored them through allegory.
The franchise also pushed television representation forward, such as when the Original Series gave Nichelle Nichols' Uhura a regular and prominent role. Although Uhura wasn’t given much to do, it was a big step, Proctor said. “In the 1960s, an American television audience was being asked to look at the bridge of the Enterprise and accept that a Black woman belonged there as an officer and a professional,” Proctor said. “That was significant.”
Nichols inspired women of all backgrounds, and not just toward scientific careers, said Bernadette Mary Dineen, another graduate student in the Kounaves Planetary Analysis & Astrobiology Lab. “Suddenly, women could see themselves in principal roles as equal to men—not just sporadically, or in stand-alone movies, but in everyday work,” she said.
Later series put a Black commander and a female captain at the center of their ensembles.
The Next Generation and Voyager likewise questioned who gets to write history: In one, Worf uncovers a suppressed chapter of Klingon history; in the other, Voyager's holographic Doctor confronts a future society that remembers his crewmates as villains.
“The historian's responsibility is to always challenge the established narrative, and not take at face value what anyone says is the reality,” Proctor said. “There are always voices that you don't know have been silenced that sometimes a little research can bring back into the light.”
Breaking new ground
Today's series continue to center characters who would once have sat outside the traditional heroic mold. Discovery begins with Michael Burnham emerging from prison; Starfleet Academy follows Caleb Mir, a teenager whose mother is a fugitive; and the animated comedy Lower Decks focuses on junior officers doing the unglamorous work of keeping a starship running.
Strange New Worlds, a prequel to The Original Series, also reinvents familiar characters for a new generation, giving figures such as Christine Chapel and Nyota Uhura richer professional and personal lives.
Star Trek has also used its alien cultures to challenge assumptions about gender, identity and love. The Trill, symbiotic beings who move among host bodies, allowed The Next Generation and Deep Space Nine to tell stories in which attraction and identity transcend the sex of a particular body. “If there are other beings out there dressing different, identifying differently than what I, as a human, understand—perhaps there is room for so much more than we were taught in our fairly binary society,” said Dineen.
Discovery extended that tradition with the franchise's first nonbinary and transgender characters, Adira and Gray Tal, as well as its first openly gay married couple, scientist Paul Stamets and physician Hugh Culber.
Strange New Worlds turns another long-running Trek concern—genetic engineering—into a question of identity and belonging. One officer hides her Illyrian heritage because Starfleet bars genetically engineered people from service.
This courtroom episode can be a metaphor for a larger question about institutional rules and who is allowed to belong there, Proctor said.
Dineen pointed to our fear of people who change their bodies from what they once were. “Not only does this plotline almost directly reveal the effects of immigration and exclusion, it is also a great allegory for trans fear in modern times,” said Dineen, adding that it reflects more literal debates too—see: “designer babies.”
Other episodes expand on our digital anxiety, taking on artificial intelligence and the fear of technologies humans can no longer fully control. “The Federation is afraid of change bringing forth the dark parts of humanity, and they lose sight of how those same changes can benefit us all,” Dineen said.
"Conversations set in a created world prove to be much less politically charged and stressful. It allows you to dive into some very delicate issues in ways that everyone can feel comfortable about,” Proctor said. “It can get you to important questions before everybody retreats into the positions they already hold about a real-world conflict.”
From oddity to necessity
As a child who felt isolated from her peers, Dineen sensed a kindred spirit in Spock, the Vulcan science officer she watched with her mother before bed. "He was different in a way his peers, coworkers and friends not only tolerated, but embraced," Dineen said. "They integrated his line of reasoning into their own decision-making, and his oddity became a necessity as they grew closer together."
In Spock's story, she saw hope for a found family of her own. "At the beginning of TOS, he was like, 'I don't care about any of you guys.' And at the end, he was sacrificing his life for Kirk," she said.
Spock embodied the tension between logic and emotion, individuality and connection. The Next Generation's android Data approached the same question from another angle, trying to understand the emotions and relationships that seemed to define humanity. "He brought a whole different kind of actually learning what it meant to be human," Proctor said.
Voyager's holographic Doctor continues that tradition, growing beyond his programming as he sings opera, falls in love and develops an identity of his own. "It's the same learning curve, but recast in a whole different way," Proctor said.
Growing up, Proctor internalized Star Trek’s ideas of friendship and loyalty, and of being willing to make choices that are not necessarily in your own best interest but are right for the people around you. “It had an influence on me in terms of ethics, morality, the cost of leadership, and what it means to take responsibility for other people,” he said.
That theme of connection and care for others continues in the newest series. Starfleet Academy's Caleb finds a home among a diverse group of friends, while A Strange New Worlds documentary prompts officers to reflect on what Starfleet has given them. "I'm here because these people are my family now. They give me hope," says Ortegas. Uhura adds, "It's the people. We make Starfleet what it is."
A dark chapter
The newer Star Trek series skew darker, in keeping with popular media's broader shift toward prestige television, with its shadowy palettes, weighty topics and long character arcs of trauma and redemption.
They also portray Starfleet in a more morally ambiguous light, often centering outsiders and underdogs who have been hurt by the institution. Discovery's Michael is initially ostracized for her criminal past, while Starfleet Academy's Caleb resents Starfleet for making his mother a fugitive.
Other stories push the critique further. Proctor sees some of these choices as a break from Gene Roddenberry's original vision.
For Proctor, however, the critique can go too far. He compares the Federation to the United Nations: an imperfect institution whose failures should be confronted without dismissing the ideals it represents. "You should always acknowledge flaws in an institution, but you can go too far in depicting everything that stands for something as implicitly flawed," he said. “They sometimes dig so deeply into the negatives that they stop trying to hope for something better.”
Discovery also depicts trauma and sexual violence more explicitly than earlier Star Trek. Dineen sees that shift as a reflection of a more troubled social and political climate—and the new tone can be benefit. “It allows viewers to process their own dark experiences and those of others, and channel them into characters on screen,” she said.
Proctor’s reaction has been “troubled” and “somewhat mixed.” Besides missing the feeling of positive potential, he’s skeptical of the proposal that humanity may have simply carried all their same problems several hundred years forward. “As a historian, I understand the argument that human beings keep repeating the same patterns,” he said. “But I also want to retain the possibility that we might recognize and eventually grow beyond some of them, that humanity will catch up with its technology.”
As a species, we still have not had Star Trek's "First Contact" moment—the encounter with alien life that, in the franchise's history, helps unite humanity around peace and progress. "There has to be global collaboration in order to achieve a lot of things we see in our science fiction, and we're far from that," Twombly said.

Where no one has gone before
That raises a question for a 60-year-old franchise: How much new ground is left to explore? Voyager was often criticized of recycling episode formulas, while Picard relied heavily on bringing back familiar faces. Discovery and other recent entries have sparked complaints that joy, fun, and heart have been replaced by pure spectacle.
Dineen is disappointed that spectacle and franchise callbacks have sometimes displaced substance and heart. And with Strange New Worlds and Starfleet Academy ending next year, the future is again uncertain. That’s compounded by the splintering of modern television audiences—while Proctor grew up with one channel that always played Star Trek after school, today there are multiple series on different paid streaming platforms, catering to different demographics.
“The Original Series knew what it was and wanted to be: a guide to humanity. Modern Star Trek is still trying to figure that out, just like us,” Dineen said.
Yet Star Trek has repeatedly imagined renewal after collapse. Discovery ends with Starfleet nearly destroyed by a disaster called the Burn, its survivors jaded and scattered—except for one man who continues, day after day, to scan for returning starships. His faith is ultimately rewarded.
Starfleet Academy picks up that thread, reviving the institution and its ideals through coming-of-age stories, campus humor and a new generation of cadets. "It really builds on a hopeful future of what Starfleet can be again," Proctor said.
The franchise is still experimenting with form, too, from Discovery's leap centuries into the future to Strange New Worlds episodes that embrace musical theater, comedy and fan-service playfulness.

That spirit of fun brings the series full circle to The Original Series. "It has the flashy, really good visual effects, and it brings some new things to the show, but it also has those familiar faces and charming interactions between the cast," Dineen said. "It's entertaining, it's a little bit campy, and it allows you to really enjoy the whimsy of Star Trek."
As Star Trek returns to the optimism, possibility and progress that made the series so powerful, Dineen thinks Star Trek's next breakthrough may need to be humanistic rather than technological. "I think we always do an oscillation where we're focused on the heavy science and then we focus on the ethos," she said. "And I think the next wave is going to have to be how we treat each other."
