10 Rules for Time Travelers
November 21st, 2013
With the Doctor Who 50th anniversary celebration happening everywhere, it seems, we think it’s a great time to look at Sean Carroll’s Rules for Time Travelers, published by Discover Magazine way back in 2009.
Sean’s eleven rules (we know, our title reads “10” but that’s just catchier.) look at time travel, paradoxes, worm holes, black holes, Star Trek, parallel universes and much more. Here’s the list of rules, but you’ll have to visit Sean’s article for the explanations and details for each:
- There are no paradoxes.
- Traveling into the future is easy.
- Traveling into the past is hard — but maybe not impossible.
- Traveling through time is like traveling through space.
- Things that travel together, age together.
- Black holes are not time machines.
- If something happened, it happened.
- There is no meta-time.
- You can’t travel back to before the time machine was built.
- Unless you go to a parallel universe.
- And even then, your old universe is still there.
Makes us wonder if the TARDIS follows all of these rules?
