You propose to bury a human time capsule. However, if we are playing by 5D Chess With Multiverse Time Travel rules, you can never really go back to that point again. You can only create an alternate timeline in which you do arrive. But somewhere out there in the multiverse, your original partner and child languish isolated in their own past. Meanwhile, you invite the two alternates to a future in which they have no past, where perhaps they never existed, or where perhaps they STILL exist as yet another set of alternates. In any case, you’ve essentially destroyed your collective ability to have human relationships outside the group, and you’ve created so many chess boards, you probably never even get to play on any of them because your opponent can just ignore them and they never become the present.
