Science fiction is the perfect window into the possibilities and perils of time travel. What would happen if you went back in time and killed your own grandparent? If you knew how to stop a presidential assassination, would time travel allow you to make your wish come true? Can we use time travel as a tool to escape the destiny of our future or mistakes of the past?

The Science of Time Travel explores time travel through your favorite science-fiction franchises, from the classic time travel paradoxes of Star Trek to the universe-crossing shenanigans of Doctor Who. Discover the real science behind questions such as:

• Can time travel really erase our past regrets like in A Christmas Carol?
• Is it worth killing people in the past to prevent a horrible future like in Terminator?
• What can we learn from living the same day over and over again like in Groundhog Day?
• Could time travel destroy our right to privacy like in Deja Vu?
• And so much more!

It's time to fire up the DeLorean to 88 mph, jump into the TARDIS hiding in plain sight, or warp space with the USS Enterprise to explore what time travel means for us.
