- K0balt 2y agoIt wouldn’t likely apply to 1980s tech, but a “fast moving” civilisation (or one capable of locally warping spacetime to a meaningful extent) could still receive the key in less than the allotted time. But if we’re going to stay unrediculous, the nova -should- work , but might not if the many-worlds interpretation (which is misleadingly named) interpretation of QM turns out to be right. The time traveler effectively brings the nova into the light-cone of the past world, altering the relationship in the MWI. Stealth might still be the most reliable.
- card_zero 2y agoI don't see how the novas (which happened long, long ago) would be stopped by anything happening in any version of the 1980s.
- DennisP 2y agoI guess the idea would be to send FTL probes into space in all directions, so they can see the light heading our way from novas and report back. However, accomplishing this seems considerably more difficult than finding an underwater buoy.
- K0balt 2y agoWhich would be hilarious when they found out the key unlocked tide pods lol.
