This reminds me of a method to develop time travel:
A thousand beautiful stone tablets are buried and sunk all around the world in multiple languages. The tablets announce the purpose of the experiment and share a series of dates and precise locations. In those places and times, a set of extremely sensitive sensors are set up to listen. If one is reasonably confident that the tablets will be discovered in a 1000 years, and if there is some unknown physics that enables sending information back in time, then a communication channel could be set up allowing the flow of future tech into the past. And worst case, we are left with a bunch of beautiful stone tablets for future generations to ponder over.
