15 Fascinating Facts That Prove How Little We Really Know About the World

According to the Saed News website and Wikipedia, the largest online encyclopedia, there are more than 6,035,554 articles in English alone, and this number is increasing every day. These articles contain a vast amount of information on various topics.

According to a legend, if you click the first link in any English Wikipedia article (excluding italicized links and those inside parentheses) and continue doing so, you will eventually reach the “Philosophy” page. In fact, there is even a Wikipedia page titled “Getting to Philosophy.” According to this page, this phenomenon applies to 97% of English Wikipedia articles. It was discovered in 2008.

Although nothing can replace Wikipedia, here are some interesting facts that may surprise even those who think they know everything. These facts show that we truly know very little about the world.
