TED-Ed: Can you solve the time traveling car riddle? | Daniel Finkel

In this video, you and the Professor must fix a time travel mishap to prevent the universe from collapsing. After a crash, you need to find two locations on Earth where you can drive a mile south, east, and north to return to your starting point. The North Pole and a circle near the South Pole provide solutions. By using Earth's spherical nature, you place time gates and successfully merge timelines, saving the universe.

What is the main issue faced by the protagonists after the crash?

• They run out of fuel.

• Their time machines are destroyed.

• They lose their memory.

• Their gyroscopes are broken.

Why must the time gates be placed at least 100 miles apart?

• To ensure enough space for the cars.

• To avoid time paradoxes.

• To prevent signal interference.

• To comply with time travel regulations.

What geographical feature is used to solve the time travel problem?

• The equator

• The North Pole

• The South Pole

• The Prime Meridian

How does traveling on a circle with a one-mile circumference help in time travel?

• It allows for infinite loops.

• It increases the speed of the DeLorean.

• It brings you back to the starting point.

• It aligns the gyroscopes perfectly.

What is the significance of the circle near the South Pole in the solution?

• It is the largest circle on Earth.

• It is the starting point for all time travel.

• It is the only place where time travel is possible.

• It allows for a one-mile eastward rotation.
