Q&A

Is it possible to encode a message in such a way that can only be read by someone or something capable of seeing into the very near future?

+0
−0

Say you have some way of seeing somewhere between a microsecond to 0.1 seconds into the future, or at least the most likely future. Is it possible,through something like a flip-book effect or some other illusion, to encode a message only another observer capable of seeing the same distance into the future could also read?

Clarifications

  1. Doesn't need to be encrypted, just laid out in/on a method or medium that enables only those with 'future-vision' to observe a message unobservable to someone without future-vision.

  2. The message must not be able to be revealed through mundane means, such as high-speed video or any kind of atypical photography.

  3. The future-sight capable observer can only see into the future or at the present, not both at the same time.

  4. It doesn't matter how briefly the message is available for our future-sight capable observers, just that only they can see it.

  5. Future-sight does not extend into space beyond the 'eye' of the observer.
