🏆 שיאי עולם מדהימים שכדאי להכיר

Earth is full of records so extreme they're hard to believe even after you double-check them. Take the Burj Khalifa in Dubai — the tallest building on the planet, standing 828 meters high, roughly twice the height of the Eiffel Tower. Getting to the top floor takes several different elevators, and on a clear day you can see for dozens of kilometers in every direction. An equally jaw-dropping record sits deep in the Pacific Ocean: the Mariana Trench. Its deepest point, called Challenger Deep, plunges about 10,935 meters down. If you dropped Mount Everest in there, its peak would still be sitting nearly two kilometers underwater. What about the world's largest hot desert? The Sahara stretches across roughly 9.2 million square kilometers — almost the size of the entire United States. Yet buried under all that sand are traces of lakes and green plants that covered the area thousands of years ago. The Great Wall of China holds a completely different kind of record: length. Counting every branch and side wall, it stretches more than 21,000 kilometers — nearly enough to wrap halfway around the Earth. And finally, the speed record: a Japanese maglev train set a world speed record of 603 km/h back in 2015 — without ever touching the tracks, since it actually floats on a magnetic field. Records like these are a great reminder of just how creative and astonishing both nature and human engineering can be.
