Post Quiz: About Time
Before you can get stuck in a temporal-causality loop, you have to understand time travel. Brush up on your temporal mechanics with this multiple-choice test.
- What statement do Albert Einstein and Ford Prefect have in common?
- 'Life is like a grapefruit.'
- 'Mostly harmless.'
- 'Time is an illusion.'
- 'I have detected disturbances in the wash.'
- What is Einstein's twin theory?
- Twins can never be identical because they are born at different times.
- Twins experience time differently.
- If one twin goes to space and the other stays home, they will age at different rates.
- A twin travelling near the speed of light will age more slowly than the one on Earth.
- What scientific instrument that you probably have in your car has validated both general and special relativity?
- Tachometer
- Speedometer
- GPS
- Anti-lock brakes
- Why did Einstein say time travel, while possible, would be very difficult to survive?
- You would be sure to kill your grandfather.
- You would have infinite mass and a length of zero, which is kind of hard on the system.
- You would be deaf and blind from 'time dilation'.
- You would have zero mass and be spaghettified.
- What is the main barrier to using wormholes for time travel?
- Their event horizons are tricky to navigate.
- They are always temporary.
- Aliens control them all.
- We haven't found any yet.
- What is the main obstacle to building a Tipler Cylinder for time travel, other than the enormous amount of mass needed?
- You'd need a place to put it that was near a neutron star.
- A Tipler Cylinder is infinitely long.
- If a Tipler Cylinder were possible, we'd already have one.
- You'd need elements that haven't been discovered yet.
- In the film Primer, why is time travel so slow?
- For every minute you go back in time, you have to stay in the time machine one minute.
- It is necessary to move in space to move in time, which requires real travel.
- The time traveller has to wait for every part of his body to catch up.
- It isn't slow. It only seems that way to the time traveller.
- In Madeleine L'Engle's A Wrinkle in Time, how is space/time folded?
- Using magical origami.
- Using sonic waves.
- By creating a cosmic torus.
- By creating a tesseract.
- How does the Doctor travel through time in his/her TARDIS?
- By using string theory.
- By travelling through every point in the universe simultaneously.
- By moving through a temporal vortex.
- By exploiting a black hole, as Stephen Hawking suggested.
- What is a 'time slip'?
- A theoretical time machine that can be created mentally, as demonstrated by Jack Finney.
- A DeLorean at 84 mph.
- A situation in which people claim to have experienced the past without a time machine.
- A consequence of time dilation.
