1. Understanding Time Travel: Is It Possible?
Time travel, a concept deeply rooted in science fiction, has captivated both writers and physicists for generations. Journeys into the past and future are explored in iconic stories, prompting the question: can we travel through time?
While Doctor Who showcases time travel through the Tardis, a craft unbound by real-world physics, the show doesn’t aim for scientific accuracy. But in reality, the question remains: can we build a time machine?
Physicists are still figuring out how time works. Confidently, traveling into the future is achievable, while traveling into the past remains wildly difficult or impossible.

2. The Science of Time: Einstein’s Relativity
Einstein’s theories of relativity revolutionize our understanding of space, time, mass, and gravity. A central tenet is that the flow of time isn’t constant; it varies depending on circumstances.
According to Emma Osborne, an astrophysicist at the University of York, time travel emerges from relativity and has real-world implications.
Traveling at high speeds, approaching the speed of light, slows down time. This is highlighted in the twin paradox, where an astronaut twin traveling at near-light speed ages slower than their Earth-bound twin. As stated by Vlatko Vedral, a quantum physicist at the University of Oxford, the traveling twin returns younger. Scott and Mark Kelly’s space mission offers a real-world, albeit less extreme, example of this phenomenon.
Furthermore, time elapses slower in intense gravitational fields, like those near a black hole. Osborne notes that your head ages faster than your feet because of Earth’s gravity.
The Doctor Who episode “World Enough and Time” and the film Interstellar illustrate the effect of gravity on time.
Relativistic effects are subtle in daily life but are significant for GPS satellites, as noted by Osborne. GPS clocks tick faster than those on Earth and must be constantly readjusted. The European Space Agency confirms that without these adjustments, Google Maps would be off by about 10km daily.
Relativity means it is possible to travel into the future without a time machine, either by traveling at near-light speeds or experiencing intense gravity, which are essentially equivalent. This allows one to experience a shorter subjective time while decades or centuries pass elsewhere.
3. Time Travel to the Past: Theoretical Challenges
Traveling to the past presents significant hurdles. Barak Shoshany, a theoretical physicist at Brock University, admits insufficient knowledge and theories.
Relativity offers theoretical options for backwards time travel, but are more speculative. Katie Mack, a theoretical cosmologist at the Perimeter Institute for Theoretical Physics, mentions the quest to rearrange space-time to enable time travel to the past.
3.1. Closed Time-like Curves
One approach involves closed time-like curves, paths through space and time that loop back on themselves. Kurt Gödel described such a path in a 1949 study.
However, Vedral notes there is no evidence for their existence in the Universe, deeming this purely theoretical. Emily Adlam, a philosopher at Chapman University, suggests that even with advanced technology, creating closed time-like curves seems unlikely.
Even if we could, repeating the same actions endlessly might be undesirable, says Vedral.
Doctor Who‘s “Heaven Sent” episode features a similar concept, where the Doctor relives the same hours for billions of years through teleportation.
3.2. Cosmic Strings
In a 1991 study, physicist Richard Gott described how two cosmic strings moving past each other could create closed time-like curves.
Cosmic strings are hypothetical phenomena from the early Universe, but none have been detected. Mack notes that there’s no reason to believe they exist or that they would move in parallel.
3.3. Wormholes
Wormholes, tunnels through space-time, could theoretically create shortcuts between distant points, as stated by Vedral.
Despite being theoretically possible in general relativity, there’s no evidence of their existence. Osborne notes that they would likely collapse under their own gravity due to intense gravitational fields.
Also, real wormholes would be microscopically tiny. Solving these issues requires vast amounts of “negative energy,” which Osborne describes as potentially existing in tiny pockets within positive energy fields, but expanding them is unlikely.
Vedral concludes that using wormholes for time travel is not a realistic proposal.
According to Albert Einstein’s theories of relativity, time can be compressed with sufficient speed relative to others.
4. Quantum Mechanics and Time Travel
Quantum mechanics, which describes the behavior of subatomic particles, presents another perspective on time travel.
Non-locality, where a change in one particle instantaneously affects another entangled particle, defies our intuitions. Einstein famously called it “spooky action at a distance.” Adlam notes that this has been experimentally verified in Nobel Prize-winning research.
To resolve the faster-than-light communication implied by non-locality, some physicists propose alternative interpretations that affect our understanding of time.
Adlam suggests that instead of instantaneous effects, the effect might travel into the future and then back to the past, creating the illusion of instantaneity.
This introduces “retrocausality,” where future events influence the past, challenging our intuitive linear perception of time.
The idea of retrocausality is not universally accepted, with some physicists finding it as unsettling as non-locality.
5. Retrocausality: Is It Time Travel?
Even if retrocausality is real, Adlam clarifies that it differs from time travel. Observations of non-locality involve tiny numbers of particles, and scaling this up would be immensely difficult.
Also, sending a message to the past isn’t feasible. If Adam’s experiment is controlled by Beth’s future experiment, Beth’s experiment must destroy all records of Adam’s experiment.
Adlam states that while a signal might be sent to the past, it would require destroying all records, making it practically useless.
6. The Verdict on Time Travel: Future vs. Past
Based on current understanding, traveling into the future is possible, while traveling into the past is highly unlikely.
These theories are based on incomplete models. Relativity and quantum mechanics are effective in specific areas but are incompatible, suggesting the need for a deeper unified theory, as noted by Shoshany.
As Shoshany concludes, certainty is impossible until a unified theory emerges.
