Mark Joseph Young on Time Travel

Can you really change the past? And if so, is it dangerous to do so?  Should you be worried about the so-called Grandfather Paradox?  What about the Butterfly Effect?  What do time travellers really need to know? 

Author Mark Joseph Young answers all these questions and more with examples from popular movies.
