Avi Loeb: NASA Ignored the Enormous Size of Interstellar Object 3I/ATLAS

NASA's Omission of Key Data

• ⚠️ During the NASA press conference on 3I/ATLAS, the object's size was not mentioned even once, despite being the central clue for understanding its properties.
• 💡 Avi Loeb emphasizes that knowing the nucleus size is crucial for calculating mass loss, dust production, water outgassing, and non-gravitational acceleration.

The Enormous Scale of 3I/ATLAS

• 🚀 Based on data from Web and Maven, the nucleus of 3I/ATLAS is estimated to be 5 kilometers across, potentially larger.
• 📊 This makes it 1,000 times more massive than Borisov and over 1 million times heavier than 'Oumuamua, a significant discrepancy compared to previous interstellar objects.
• 📈 Statistically, detecting such a large object as the third interstellar visitor is extremely improbable, as smaller objects should be far more numerous.

Unusual Characteristics and Trajectory

• 🔬 The nickel-to-iron ratio in 3I/ATLAS is anomalous for a comet, showing more nickel than iron, which is typically found in industrial alloys.
• ⚡ Its jets are observed to be tightly collimated, straight, and stable, which is unexpected for an object rotating every 16 hours.
• ✨ 3I/ATLAS arrived on a trajectory almost perfectly aligned with the plane of the planets, allowing extensive observation, a rare coincidence (1 in 500 chance).

Challenging Scientific Models

• 🧠 These anomalies suggest that current models of interstellar debris and planetary formation are incomplete or incorrect.
• 🌌 The object's enormous size implies it either formed in a rare environment or was ejected by an extreme event, such as a stellar flare or catastrophic planetary impact.
• 🔭 If 3I/ATLAS is a natural comet, its size indicates that the star system where it formed operates differently from known systems, potentially involving a massive Kuiper belt analog or runaway ice accumulation.

Embracing Scientific Curiosity

• ✅ Avi Loeb stresses that anomalies are the birthplace of discovery, and ignoring them risks missing significant insights.
• 🔍 He encourages scientists to investigate surprises with humility, curiosity, and openness, rather than forcing unusual observations into familiar categories.
• 🗓️ Upcoming observations around December 19th will be crucial for determining its true size, density, jet mechanics, and other properties.
