I'm a time traveler. Yes I know it's amazing for you to grasp but once Jebsus invented time travel in the mid 54th century we all became time travelers (he open sourced it).
Now recently I came across a ring made of foreverium I would like to keep safe, said ring is one of a kind & can't be reproduced as it is made from the entire universe supply of foreverium atoms, a material which was only created in small quantities during the big bang. Aside from its rarity you can consider it being a normal ring in every way that matters.
Said material also makes this ring very expensive & I would like to keep it safe, the problem is how can I design a safe place to keep it when every thief on Earth can just time travel to a period where the safe\alarm\etc broke down due to rust\old age\etc?
You can assume the following:
- foreverium will always keep its state & shape.
- There is no more foreverium than what's in the ring.
- I can't move the ring or safe, I need to pick a spot where it will be safe,
- No living guards, the future is fully automated.
- Machines have a shelf life, no matter how long it is it will break at some point so the thief will be able to just time jump after that date to bypass a broken machinery.
- Money and resources are not a problem, if it can be done I can afford it.
- I can't hide it somewhere it will never be found, time travel leaves a very detectable signal which means every step I've taken in life since my first jump (which already happened) is tracked.
- Time travel is easy, it takes nothing more then a special wrist watch everyone has.
