Some scientists, such as Stephen Hawking, believe it's possible that there are billions and billions of universes. Each universe has a different possible consequence for every action. In the universe we live in, for example, George Bush became President of the USA in January 2001 , and Greece won the European Cup in July 2004. But in other universes different things happened.Imagine if that's true! In some universes, your parents didn't meet, so you weren't born. In another universe, a meteor didn't strike the Earth, so the dinosaurs didn't become extinct. In a different universe, your best friend won the lottery last summer and moved to a bigger house.In another parallel universe, you started learning English a year earlier, so you did this book last year! Somewhere else, Madonna wasn't discovered, and so didn't make any records. In another universe,Van Gogh was recognised as a great painter during his lifetime, and so didn't die in poverty.And perhaps in several universes, there were enough lifeboats on the Titanic and so everyone on board survived. It makes you think, doesn't it?
