The Burj Khalifa in Dubai, completed in 2009, remains the world's tallest building at 829 meters. Its innovative design, including a Y-shaped structure and a hexagonal core, allowed it to surpass previous height records. Despite several attempts, no building has been able to beat its record in the past 13 years. The video explores the challenges of building extremely tall structures, including wind resistance, weight, and materials limitations. Theoretically, it may be possible to build a structure over 2 miles (3 km) tall using advanced materials like carbon fiber, but practical limitations, including human physiology and socio-economic factors, make it unlikely. The video concludes that Burj Khalifa will likely remain the world's tallest building for the foreseeable future.
