ol Facts about the World that You Probably Didn't Know" Did you know that there's a species of jellyfish that is biologically immortal? Or that the shortest war in history lasted only 38 minutes? These are just some of the many cool facts about the world that you probably didn't know. In this article, we will explore some of the most interesting and unbelievable tidbits of information that will surely surprise you. Let's start with a creature that is near and dear to many people's hearts - the whale. Did you know that the blue whale is not only the largest animal on Earth but also the loudest? Its vocalizations can reach up to 188 decibels, which is louder than a jet engine. Another interesting fact about whales is that their closest living relatives are actually hippos. Moving on to the realm of history, did you know that the Great Wall of China is not visible from space? This popular belief is actually a myth. Although the Wall is an impressive feat of engineering, it cannot be seen from low-earth orbit. However, there is something that can be seen from space - the Pyramids of Giza. These ancient structures are the only remaining Seven Wonders of the World and are visible from the International Space Station. Speaking of space, did you know that the nearest star system to our own - Proxima Centauri - has a potentially habitable planet? Discovered in 2016, Proxima b orbits its star within the habitable zone, which means that liquid water could possibly exist on its surface. This discovery has given scientists hope in the search for extraterrestrial life. Moving on to the animal kingdom, did you know that there's a bird called the Kakapo that can't fly? This flightless parrot is not only the heaviest but also the longest-living parrot with a lifespan of up to 90 years. Another interesting fact about animals is that the largest flower in the world is the Rafflesia arnoldii, which is found in Southeast Asia. This flower can grow up to three feet in diameter and smells like rotting flesh to attract pollinators. And finally, did you know that there are more possible iterations of a game of chess than atoms in the observable universe? This mind-boggling fact is due to the large number of possible moves in a chess game (estimated to be around 10^120). This means that every game of chess is essentially unique and has never been played before. These are just some of the many cool facts about the world that will make you scratch your head in disbelief. From the loudest animal on Earth to the potentially habitable planet in our neighboring star system, the world is full of wonders and surprises waiting to be discovered.
