Physicist Brian Cox expressed gratitude towards YouTube for removing deepfake accounts impersonating him and spreading misinformation about comet 3I/ATLAS. The interstellar comet, discovered on July 1, 2025, is unique as it does not orbit the Sun and is one of only three identified interstellar comets. Cox emphasized that 3I/ATLAS is a natural celestial body, dismissing claims that it could be an alien spacecraft. He raised concerns about long-term solutions to the issue of deepfakes, especially in relation to science and politics, highlighting the broader implications of AI-generated misinformation.

What is comet 3I/ATLAS and why is it significant?

Comet 3I/ATLAS is an interstellar comet discovered in 2025 that does not orbit the Sun and is over 7 billion years old. It is significant because it provides scientists with a rare opportunity to study a cosmic body that has traveled from outside our Solar System, offering insights into the early solar system and the formation of celestial objects.
