Description

You’ve probably daydreamed about traveling through time.  Well, it turns out, it is possible… at least in some senses.  For instance, astronauts that spend long periods in space traveling at thousands of miles an hour have actually traveled further in time than we have.  This video discusses Einstein’s theory of relativity and the physics of real time travel.  It ends by musing over what the future of time travel may be like.

Discussion Questions

• What does the train experiment show about how time moves differently for different people?
• What kind of time travel may be possible in the future?  And how?
• What kinds of time travel probably aren’t physically possible?
• What would you do if you could travel 10 years into the future?  100 years?  1 million years??
