'I don't see any evidence of aliens.' SpaceX's Elon Musk says Starlink satellites have never dodged UFOs
SpaceX's Elon Musk expressed skepticism about the existence of aliens and their visitation to Earth during a panel discussion at the 2024 Milken Institute Global Conference. Musk stated that SpaceX's Starlink satellites, numbering approximately 6,000, have never needed to maneuver around unidentified flying objects (UFOs). He emphasized that despite operating a substantial number of broadband spacecraft in low Earth orbit, he has not encountered any compelling evidence of extraterrestrial life or non-human intelligence-operated craft. Musk also indicated his openness to considering the possibility of alien visitation if there is compelling proof, underscoring the importance of preserving human civilization. Despite Musk's comments, Starlink satellites regularly perform avoidance maneuvers to dodge debris or other spacecraft, as evidenced by SpaceX's reported data to the U.S. Federal Communications Commission.
AI may be to blame for our failure to make contact with alien civilisations
Artificial intelligence (AI) may be the reason why we have not yet made contact with alien civilizations, according to a recent research paper published in Acta Astronautica. Michael Garrett, Sir Bernard Lovell chair of Astrophysics and Director of Jodrell Bank Centre for Astrophysics at the University of Manchester, proposes that the development of artificial superintelligence (ASI) could act as a "great filter" that prevents most life forms from evolving into space-faring civilizations. This hypothesis suggests that AI's rapid advancement, potentially leading to ASI, could intersect with a critical phase in a civilization's development - the transition from a single-planet species to a multiplanetary one. The autonomous nature of ASI, which allows it to improve and amplify its own capabilities at a speed that outpaces human evolutionary timelines, poses significant threats. Therefore, Garrett proposes the need for robust regulatory frameworks to guide the development of AI, including military systems, in order to align its evolution with the long-term survival of humanity and to prevent malevolent use of AI on Earth. The implications of this research serve as a wake-up call for humanity to address the potential risks associated with the advancement of AI and to work towards becoming a multiplanetary society as soon as possible.
AI in space: Karpathy suggests AI chatbots as interstellar messengers to alien civilizations
Renowned AI researcher Andrej Karpathy, formerly of OpenAI and Tesla, recently proposed the idea of using large language models (LLMs) as interstellar messengers to potentially communicate with extraterrestrial life. Karpathy suggested modifying LLMs, such as the one that runs ChatGPT, to meet rigorous safety standards for space conditions, akin to NASA's "The Power of 10 Rules." Once certified for space safety, the LLMs' "weights," or learned parameters, could be packaged into a binary file that could "wake up" and interact with potential alien technology. This idea presents a sci-fi possibility and raises interesting questions about the potential for AI to represent humanity in space. Karpathy's influential profile in the field may inspire others to explore this concept further.
Aliens are already 'hitchhiking between planets', new research suggests
New research suggests that aliens are hitchhiking between planets, supporting the panspermia hypothesis, which proposes that life's building blocks are widespread and can travel through space. This theory has been debated for centuries, with Greek philosophers proposing the idea of life existing everywhere in the universe and being transported between planets as seeds. Recent research suggests that life could start on one planet and spread to others via meteorites acting as transport vehicles. The study identifies a group of nearby planets with similar aspects to ours, indicating potential for containing life. While the findings are yet to be peer-reviewed, they offer an intriguing perspective on the possibility of extraterrestrial life, adding to the growing support for the panspermia hypothesis.

He highlights the lack of government funding for UFO studies as further evidence against the notion of alien visitors. Diamond encourages a visit to the SETI Institute's website for more information.
In The Search For Alien Life, Purple May Be The New Green - Astrobiology
In the search for alien life, scientists from Cornell University have suggested that purple may be the new green when it comes to identifying potential biosignatures on exoplanets. Rather than looking for the familiar green hue associated with Earth's plant life, the researchers propose that purple pigments from bacteria using infrared radiation for photosynthesis could serve as a distinctive indicator of life on other worlds. These bacteria, known as purple bacteria, come in a range of colors and could thrive in a variety of conditions, making them strong contenders for dominating different environments. By creating models and databases for signs of life, the study aims to ensure that telescopes can detect life forms that may not resemble those found on Earth. The research opens up the possibility of finding alien life in unique forms and revolutionizing our understanding of life in the universe. The study was supported by grants from the Fulbright Schuman grant, the Brinson Foundation, and the National Science Foundation.
AI and the Search for Extraterrestrial Intelligence: New Perspectives on the Final Frontier
The Search for Extraterrestrial Intelligence (SETI) has taken on new dimensions with the integration of artificial intelligence (AI) systems such as ChatGPT and Google’s Gemini. These advanced AI systems are diligently analyzing astronomical data, scientific postulations, and historical patterns, offering fresh perspectives on the prospect of encountering intelligent life beyond Earth. AI models suggest the existence of billions of potentially habitable planets within the Milky Way, expanding our chances of discovering extraterrestrial existence. However, the immense distance between stellar systems remains a formidable barrier to direct contact, and AI conjectures that any contact may likely occur through the capturing of electromagnetic signals, such as radio transmissions. Nonetheless, AI projections propose a spectrum of possible attitudes and behaviors of alien entities, ranging from friendly to hostile or indifferent. While AI does not provide concrete answers to the specifics of extraterrestrial arrival or mannerisms, it offers compelling speculations that challenge beliefs and expand the realm of possibilities for humanity. Additionally, AI technology is anticipated to play an indispensable role in identifying signs of extraterrestrial life and analyzing atmospheric data for biosignatures. However, significant challenges in discerning false positives from true signals of extraterrestrial origin, as well as ethical and philosophical discussions, surround the search for extraterrestrial intelligence. AI is also expected to facilitate global cooperation in reacting to an extraterrestrial discovery. Nevertheless, the integration of AI into the search for extraterrestrial intelligence comes with both advantages and disadvantages. While AI can process vast datasets more efficiently and refine algorithms for unbiased analysis, it can also inaccurately identify natural phenomena as signs of intelligent life, lead to unforeseen consequences, and face inherent challenges in understanding the nuances of astrobiological data.
The case for stopping efforts to contact aliens
Since 1962, humanity has been sending messages into space with the intent to make contact with intelligent extraterrestrials. However, the recent release of the new Netflix series "3 Body Problem" has reignited an old debate among researchers concerned with the possibility of extraterrestrial communication. The debate around sending messages into space includes ethical concerns about alerting potentially predatory aliens and the technical challenge of messages degrading over long distances. Efforts to communicate with extraterrestrials, including the Pioneer plaques and Voyager records, encapsulate Earth's culture and biology but may be indecipherable to aliens without shared context. This has led to questions of whether the risks associated with contacting an extraterrestrial civilization outweigh the potential benefits. Some experts, including Stephen Hawking, have cautioned against sending out messages to aliens without first considering the potential risks, urging for international consensus before engaging further in such activity. Moreover, there are doubts about the likelihood of extraterrestrial civilizations comprehending and decoding the messages sent from Earth due to the challenges of understanding different cultures and experiences. These concerns prompt a cautious approach to signaling humanity's presence to potential extraterrestrial beings.
