The Roots of Coincidence

Have you ever said something and then later heard someone else talking about the same thing? That is called a coincidence, and it happens all the time! A coincidence is when two things happen at the same time, but they are not related to each other. It's almost like a funny joke from the universe! The roots of coincidence have been studied since ancient times, but nobody knows exactly why they happen. Some scientists say it’s just a result of random chance; others believe that coincidences are caused by our minds unconsciously making connections in the world around us. Whatever the cause, coincidences can be fascinating and fun!
