马斯克回应星际天体争议：若发现外星生命必公布

Core Insights - Elon Musk discussed the scientific community's debate regarding a newly discovered interstellar object, 3I/ATLAS, emphasizing that he would publicly disclose any evidence of extraterrestrial life [3][4] - The object, observed for the first time in July, has a diameter between 440 meters and 5.6 kilometers and is traveling at a speed exceeding 200,000 kilometers per hour, making it the third interstellar visitor observed by humanity [3] - The composition of 3I/ATLAS shows significant differences from known comets, particularly the detection of nickel without the usual accompanying iron, raising questions about its origin [3] - A Harvard astronomer suggested that 3I/ATLAS might not be a naturally formed comet but rather a probe or mothership from an extraterrestrial civilization, calling for more observational data to further research [3] - Musk noted that if the object were primarily composed of nickel, its mass would be enormous, potentially leading to catastrophic consequences if it collided with Earth [3] Summary by Sections - Interstellar Object Discovery - 3I/ATLAS is the third interstellar object observed, with a diameter of 440 meters to 5.6 kilometers and a speed over 200,000 kilometers per hour [3] - Its trajectory and material composition differ significantly from known comets, prompting scientific speculation [3] - Scientific Speculation - The detection of nickel in the gas cloud surrounding 3I/ATLAS, without the presence of iron, raises questions about its origin [3] - A Harvard astronomer proposed that it could be an artificial object rather than a natural comet, urging for more data to support further investigation [3] - Musk's Statements - Musk stated he would publicly announce any evidence of extraterrestrial life and emphasized he would never commit suicide, addressing conspiracy theories about whistleblowers [4] - He highlighted the potential dangers of 3I/ATLAS if it were primarily nickel, suggesting severe consequences in the event of a collision with Earth [3]
