Before Reading

A dream machine for time travel, Time Machine!
Among Hollywood movies, there is an old science fiction movie series called Back to the Future. In each movie, Marty, a high school student, uses a time machine that Dr. Brown, an inventor, built from a modified sports car to travel through time.
Time travel into the past or the future has always stirred up our interest and curiosity. But is time travel really possible? Besides, can a time machine needed for such a trip actually be built? According to Einstein’s theory of relativity, time passes differently for people depending on gravity or motional states. Therefore, even though there are twins who were born at the same hour on the same day, one can be a young man and the other can be a middle-aged man when they meet later in life after having different experiences. But time travel into the past or the future isn’t possible right now. Still, don’t be disappointed. Technological advances are always beyond our expectations, so who knows time travel might come true some day?
