Is an alien spacecraft visiting our photo voltaic system? A wave of movies that includes famed physicist Michio Kaku making that declare have been spreading on social media. However the scientist is warning the general public the clips are literally AI deepfakes spreading misinformation.
“There was a sudden rise of fraudulent unauthorized deep pretend AI movies, impersonating me, deceptive the general public with loopy false claims that aren’t my very own,” Kaku tweeted this week.
The movies look convincing and exploit an actual interview Kaku gave about 3I/ATLAS, which NASA tracks as a comet. It made the rounds after a current analysis paper speculated that 3I/ATLAS is perhaps “alien know-how,” regardless of the overwhelming consensus it’s not.

“The bulk faction says ‘What’s all of the fuss about? I imply It’s only a rock from outer area,’” Kaku instructed Newsmax. “One other faction, nevertheless, says ‘Now, wait a minute. Maybe, this can be a customer. An clever customer from one other photo voltaic system.’”
That’s as a result of 3I/ATLAS is the third object that astronomers have ever detected originating from exterior our photo voltaic system. Within the interview, Kaku provides that the scientific group will search for indicators that 3I/ATLAS’s velocity will increase because it circles the Solar—a sign that the mysterious object isn’t any mere comet, however options synthetic propulsion. “If it picks up further power on its flyby, that may clinch it. Meaning there’s further terrestrial intelligence concerned,” he stated within the interview.
Theoretical physicist Avi Loeb has been probably the most vocal determine pushing the speculation that 3I/ATLAS might be an alien spacecraft, regardless of proof that it’s ejecting water vapor like a comet, though at a staggering fee.
The issue is that the AI-generated movies of Kaku take issues additional by exploiting his picture and voice to speak as if 3I/ATLAS is nearly actually an alien spacecraft or recon car, and that it beamed power to Mars or the Solar. Some clips even counsel the mysterious nature of 3I/ATLAS is already recognized to the US authorities and a cover-up is happening.
Physicist Brian Cox additionally stories seeing AI deepfakes of himself pushing comparable misinformation on YouTube. “We maintain telling them and they’re bloody sluggish,” he tweeted about attempting to get Google to take away the movies.
Kaku has additionally been calling on YouTube and TikTok to do extra to crack down. “I name on AI thought leaders to place actual efforts into stopping this blatant abuse of their innovations,” he added.
Within the meantime, others have been monitoring for modifications to 3I/ATLAS, which reached its perihelion as we speak, the purpose in its orbit closest to the Solar. Loeb has stated, “For a spacecraft, perihelion is the optimum time for both acceleration or deceleration by an impulse from an engine, due to the gravitational help from the Solar.” So, observers have been carefully awaiting any modifications to 3I/ATLAS and its trajectory.

I am at present primarily based in San Francisco, however beforehand spent over 5 years in China, masking the nation’s know-how sector.
Since 2020, I’ve lined the launch and explosive development of SpaceX’s Starlink satellite tv for pc web service, writing 600+ tales on availability and have launches, but in addition the regulatory battles over the growth of satellite tv for pc constellations, fights with rival suppliers like AST SpaceMobile and Amazon, and the hassle to broaden into satellite-based cell service. I’ve combed via FCC filings for the newest information and pushed to distant corners of California to check Starlink’s mobile service.
I additionally cowl cyber threats, from ransomware gangs to the emergence of AI-based malware. Earlier this 12 months, the FTC pressured Avast to pay customers $16.5 million for secretly harvesting and promoting their private info to third-party shoppers, as revealed in my joint investigation with Motherboard.
I additionally cowl the PC graphics card market. Pandemic-era shortages led me to camp out in entrance of a Greatest Purchase to get an RTX 3000.
