Movie Time Travel Debunked by Scientists

View fullsize

There are a ton of movies that deal with time travel, and most of them are really great. When it comes to time travel in these stories, it doesn't really matter if it's possible or not, it's all about the imagination and wonder of it all. 

The Screen Junkies wondered how far away from time travel technology we are, so they enlisted the expertise of University of Southern California physicist Dr. Clifford Johnson and JPL NASA scientist Christina Heinlein. They got them to break down the physics of time travel in films such as Back to the Future, Bill & Ted’s Excellent Adventure, Planet of the Apes, X-Men: Days of the Future Past, Edge of Tomorrow, and even some TV shows like Quantum Leap. 

Even if time travel isn't really possible, it still makes for an entertaining plot point in the movies!
