Back to the Future

• Marty travels back in time

• Causes an event which could prevent him from being born– Danger: Infinity loop

• Manages to fix the timeline– although with some differences

Back to the Future II

• In alternate 1985 the Doc has not built a time machine

• How then could he have gone into the future where old Biff stole the time machine?

Bill and Ted

• Rufus travels back in time to make sure they don’t fail history causing their band, Wyld Stallyons to never exist– But if they did fail how does Rufus know

about Wyld Stallyons?

• After many trips through time they have significantly altered the timeline

Terminators

• Machines are sent back in time to alter history

• If the Terminator succeeded, he would not have been sent back in time in the first place

Doctor Who

• Uses a type 40 TARDIS for time travel

• Can travel from any point in space-time to any other point

• Could lead to many temporal anomalies

Conclusion

• Be careful when travelling backwards in time

Infinity loops could cause a chain reaction that would unravel the very

fabric of the space-time continuum and destroy the universe.
