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].

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 [1][3][7]. Group 1: Rumor Details - The rumor states that on August 12, 2026, the world will experience 7.3 seconds of weightlessness, leading to millions of casualties and infrastructure damage, with an estimated 40 to 60 million deaths [3][5]. - It attributes the cause to the collision of gravitational waves from two black holes, which was supposedly predicted with a 94.7% probability in 2019 [5][12]. - The rumor has been circulating since early this year, having been revived from a 2024 leaked NASA document [5][17]. 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, as gravity is determined by the mass of the Earth, which cannot simply disappear [7][9]. - The assertion that people and objects would slowly rise to 15-20 meters contradicts physical laws; if gravity were to vanish, objects would be ejected at high speeds rather than rising slowly [11][20]. - The impact of gravitational waves on Earth is negligible, requiring extremely precise instruments to detect, and the effects of two colliding gravitational waves are minimal [14][16]. Group 3: Astronomical Events - On August 12, 2026, a total solar eclipse will occur, which is a common astronomical event that has been accurately predicted [17][18]. - The eclipse will not affect Earth's gravitational field; it will only block sunlight temporarily, leading to minor changes in surface temperature and tidal forces [20]. Group 4: Public Awareness and Rumor Prevention - Similar doomsday rumors have appeared in the past, exploiting public fear of the unknown and misunderstanding of astronomical events [22]. - Experts recommend verifying claims through authoritative sources and applying basic scientific knowledge to discern the truth [22].

Core Viewpoint - The recent doomsday warning regarding a gravitational anomaly caused by a black hole merger during the solar eclipse on August 12, 2026, is identified as a complete "science fiction story" with no scientific basis [1]. Group 1: Misinterpretation of Events - The only real event referenced in the rumor is the solar eclipse occurring on August 12, which is a natural phenomenon where the moon temporarily blocks sunlight from reaching parts of the Earth, affecting light but not gravitational forces or orbital mechanics [1]. - The narrative surrounding the solar eclipse has been misleadingly framed as a potential "gravitational collapse," which is scientifically unfounded [1]. Group 2: Clarification of Gravitational Concepts - The term "gravitational anomaly" mentioned in the rumors does not equate to "gravitational collapse." For instance, astronauts in the Chinese space station experience weightlessness not due to a lack of gravitational force but because they are in free fall, creating a sensation of floating [2]. - Einstein's theory posits that gravity is a result of mass causing curvature in spacetime, meaning that as long as mass exists, gravitational effects will persist [2]. Group 3: Exaggeration of Gravitational Waves - The rumors exaggerate the impact of gravitational waves, which are extremely weak signals that require highly sensitive instruments for detection. The idea that gravitational waves could cause global disasters is a significant distortion of physical reality [2]. - Historical patterns show that similar doomsday rumors, such as those involving planetary alignments or artificial black holes, have repeatedly been debunked by scientific facts [2].

Core Viewpoint - The warning about a global disaster caused by gravitational waves during the solar eclipse on August 12, 2026, is a complete fabrication and has been debunked by scientists [1]. Group 1: Misconceptions about the Solar Eclipse - The rumor claims that a black hole merger will generate gravitational waves leading to a global gravity anomaly lasting 7.3 seconds, potentially resulting in 40 million casualties [1]. - The solar eclipse itself is a natural phenomenon where the moon temporarily blocks sunlight, having no impact on Earth's gravitational field or orbital mechanics [1]. Group 2: Clarification on Gravity and Gravitational Waves - The term "gravity anomaly" is misused; astronauts in the Chinese space station experience weightlessness not due to a lack of gravity but because they are in free fall, maintaining a speed of approximately 8 kilometers per second in orbit [2]. - Gravitational waves are extremely weak signals that require highly sensitive instruments for detection, and the idea that they could cause global disasters is a gross exaggeration [2].
