    B Exploiting radiocarbon dating for FTL communication

    Well, there's only one observer, the terrestrial one. In the observed frame, the distant Starshot sample should age slower. Consider a simple binary message: If life is detected, measure the first half of memory. Otherwise measure the second half. In the terrestrial wafer, does the remote...
