真相来了丨“地球将失重7秒”是真的吗？专家辟谣

Core Viewpoint - The viral "doomsday warning" claiming that Earth will experience weightlessness for 7 seconds on August 12, 2026, is a baseless rumor with no scientific foundation [2][5][6]. Group 1: Rumor Details - The rumor states that on August 12, 2026, the world will experience 7.3 seconds of weightlessness, allegedly based on a leaked NASA document called the "Anchor Plan," which supposedly costs over $80 billion to address this gravitational anomaly [2][4]. - It describes a catastrophic scenario where unanchored people and objects would rise 15 to 20 meters, crash into ceilings, and then fall back, resulting in an estimated 40 to 60 million casualties and a global economic collapse lasting over 10 years [2][4]. Group 2: Scientific Analysis - Experts from the Chinese Academy of Sciences assert that the claim of "Earth losing gravity for 7 seconds" is entirely false and lacks scientific basis, as gravity is determined by Earth's mass and cannot simply disappear [5][6][8]. - The assertion that people and objects would slowly rise contradicts physical laws; if gravity were to vanish, they would be ejected at high speeds rather than rising gradually [9]. Group 3: Gravitational Waves - The rumor attributes the supposed event to the collision of gravitational waves from two black holes, but experts clarify that the impact of such waves on Earth is negligible and requires highly sensitive instruments to detect [10][12]. - The energy changes from colliding gravitational waves are so minimal that they can be disregarded in terms of any potential harm to Earth [10][12]. Group 4: Astronomical Events - The date of August 12, 2026, coincides with a predicted solar eclipse, a common astronomical event that has been accurately forecasted by astronomers [13][15]. - Solar and lunar eclipses occur regularly and do not affect Earth's gravitational field; they merely cause temporary changes in surface temperature and tidal forces [16]. Group 5: Public Awareness and Rumor Prevention - Similar doomsday rumors have circulated in the past, often exploiting public fear of the unknown and misunderstanding of astronomical events [17][19]. - Experts recommend verifying claims through authoritative sources, applying basic scientific knowledge, and being cautious of sensationalized language associated with "leaked documents" [19].
