The system, called "QuakeNet AI", uses quantum computing combined with machine learning to analyze seismic patterns invisible to current technology. Dr. Sarah Chen, lead researcher, claims this could save millions of lives and prevent billions in damages. The technology will be commercially available by 2026 according to insider sources. This comes just weeks after similar breakthroughs in cancer detection AI. What do you think about this amazing discovery? #AI #Earthquake #MIT #Science"""],
-                ["""SpaceX conducted another major test for their Starship program yesterday, with Elon Musk claiming on social media that Flight 10 is "ready to revolutionize space travel forever." The company fired up all 33 Raptor engines on their Super Heavy booster at the Starbase facility in Texas. According to various reports and this detailed article (https://www.space.com/space-exploration/launches-spacecraft/spacex-fires-up-super-heavy-booster-ahead-of-starships-10th-test-flight-video), the test was part of preparations for the upcoming 10th test flight. However, some critics argue that SpaceX is moving too fast without proper safety protocols, especially after Flight 9 experienced issues. The FAA is still investigating the previous mission where both the booster and ship were lost. Industry experts remain divided on whether this aggressive testing schedule is beneficial or dangerous for the future of commercial spaceflight. 🚀 #SpaceX #Starship #Space"""]

The system, called "QuakeNet AI", uses quantum computing combined with machine learning to analyze seismic patterns invisible to current technology. Dr. Sarah Chen, lead researcher, claims this could save millions of lives and prevent billions in damages. The technology will be commercially available by 2026 according to insider sources. This comes just weeks after similar breakthroughs in cancer detection AI. What do you think about this amazing discovery? #AI #Earthquake #MIT #Science"""],
-                ["""SpaceX conducted another major test for their Starship program yesterday, with Elon Musk claiming on social media that Flight 10 is "ready to revolutionize space travel forever." The company fired up all 33 Raptor engines on their Super Heavy booster at the Starbase facility in Texas. According to various reports and this detailed article (https://www.space.com/space-exploration/launches-spacecraft/spacex-fires-up-super-heavy-booster-ahead-of-starships-10th-test-flight-video), the test was part of preparations for the upcoming 10th test flight. However, some critics argue that SpaceX is moving too fast without proper safety protocols, especially after Flight 9 experienced issues. The FAA is still investigating the previous mission where both the booster and ship were lost. Industry experts remain divided on whether this aggressive testing schedule is beneficial or dangerous for the future of commercial spaceflight. 🚀 #SpaceX #Starship #Space"""]
