According to IGN, physicist Brian Cox has publicly thanked YouTube for taking down accounts that used AI technology to create deepfakes of him claiming comet ATLAS 3i is an alien spaceship. The University of Manchester professor, whose complaint tweet garnered 618,500 views, described the content as “AI shite” and established a rule for his followers: “if I appear to say something that you agree with and you are a UFO nobber, flat earth bell end or think comet ATLAS 3i is a spaceship, it’s fake.” While YouTube removed the more prominent accounts, Cox expressed uncertainty about long-term solutions, noting the particular danger when similar tactics are applied to politics or other scientific areas. The incident highlights growing concerns about synthetic media’s impact on public discourse.

The Deepfake Epidemic Hits Science Communication
What makes Cox’s case particularly troubling is the targeting of scientific authority figures to spread misinformation about actual celestial events. Comet 3I/ATLAS represents a genuine scientific marvel—an interstellar visitor that formed around another star billions of years ago. By co-opting a respected scientist’s likeness to promote pseudoscientific claims, these deepfake creators undermine public trust in both individual experts and the scientific process itself. The timing is especially damaging as legitimate astronomers are actively studying this rare interstellar object, creating confusion about what constitutes real scientific discovery versus manufactured conspiracy theory.
YouTube’s Reactionary Approach to Synthetic Media
Platforms like YouTube face a fundamental structural problem: their content moderation systems remain largely reactive rather than proactive. As Cox noted in his tweets, the response was “bloody slow” and limited to “more prominent accounts,” suggesting smaller channels continue spreading similar content. This piecemeal approach creates a whack-a-mole scenario where new accounts can spring up faster than old ones are removed. The economics favor bad actors—creating AI-generated content is increasingly cheap and scalable, while human-led moderation remains expensive and slow.
Beyond Celebrity Deepfakes: The Broader Threat
While Cox’s situation involves relatively harmless comet conspiracy theories, the same technology poses existential risks to democratic processes. Imagine deepfakes of political leaders declaring war, central bankers causing market panic, or public health officials spreading dangerous medical misinformation. The technical barrier for creating convincing synthetic media has dropped dramatically, while detection methods struggle to keep pace. As Cox correctly identified, the core issue isn’t about one physicist’s digital likeness—it’s about establishing trust mechanisms for an internet where seeing is no longer believing.
The Unsolved Problem of Scale and Verification
Current platform responses—including the takedowns Cox acknowledged—fail to address the systemic nature of synthetic media distribution. Even when major accounts are removed, the content often migrates to smaller channels, private groups, or alternative platforms. What’s needed are cryptographic verification systems that allow content creators to digitally sign their work, providing a tamper-proof method for authentication. Some news organizations have begun experimenting with content provenance standards, but widespread adoption remains years away. Until then, public figures like Cox will remain vulnerable to having their credibility weaponized against them.
The Future of Trust in Digital Media
The solution likely involves multiple approaches: better detection algorithms, clearer platform policies, public education about synthetic media, and potentially legislative action. However, as Cox’s experience demonstrates, we’re in a transitional period where the technology for creating convincing fakes has outpaced both detection capabilities and regulatory frameworks. The physicist’s eloquent description of the comet’s natural origins represents the human side of this battle—experts repeatedly correcting the record while automated systems spread misinformation at scale. Until platforms develop more sophisticated, proactive approaches to synthetic media, even prominent figures will find themselves fighting digital doppelgangers spreading “nonsense” to millions.
