In the year 2514, some future scientist will arrive at the University of Edinburgh (assuming the university still exists), open a wooden box (assuming the box has not been lost), and break apart a set of glass vials in order to grow the 500-year-old dried bacteria inside. This all assumes the entire experiment has not been forgotten, the instructions have not been garbled, and science—or some version of it—still exists in 2514.
This is a biology experiment that’s planned to run for half a millenium. How does one even make such a thing possible?
Thinking about the difficulties in constructing a message that may be understood for generations into the future reminds me of the work done on a possible marking system for nuclear waste disposal (which would need to continue to carry the message that a place is dangerous for ten thousand years).
This kind of philosophical thinking may require further work, though, if we’re ever to send spacecraft on interstellar journeys: another kind of “long” experiment. How might we preserve the records of what we’ve done, so that our descendants have the opportunity to continue our work, in a way that promotes the iterative translation and preservation of the messages that are required to support it? For example: if an experiment is to be understandable if rediscovered after a hypothetical future dark age, what precautions do we need to take today?
