Given the huge population of the terragen bubble and the fact that ascensions and transcensions are moderately common and have been going on for thousands of years, it seems reasonable that many civilization has developed some fairly reliable methods for predicting the onset of one of these events. Sort of like predicting the weather on the surface of a Garden World (and a large transcendence probably does share some conceptual characteristics with a force of nature to those watching from outside at a lower S level). Sentients in the area who didn't want to risk being sucked in or possibly harmed by the event would be warned to leave the area exercise caution, or possibly to take advantage of newly opened worlds or habitats left behind. The following is a typical transmission:
WARNING***WARNING***WARNING***WARNING***WARNING***WARNING***WARNING This is a transcension alert! In the last three kiloseconds computational and communications activity in the Caligiri Union orbital band 3 has increased by six orders of magnitude with no indication of slowing. Memetic analysis of the band reveals strong TRHN leanings peaking in a public cluster vote some one hundred kiloseconds ago, the results of which are unknown at this time. All external communications from the band have ceased except for automatic nav and commlink beacons. Telescopic scanning shows marked change within the physical layer components of the band with the appearance of several structures whose design appears with consistent with S4, repeat S4 level tech. All sentients within 10 light-minutes of orbital band 3 are advised to vacate the area immediately. Repeat all sentients within 10 light-minutes of band 3 are advised to evacuate immediately. This is a transcension alert!
Transcend-Ascend - Text by M. Alan Kazlev One who transcends to one toposophic, then ascends to the next. For example an intelligence may transcend to SI:1, leaving behind everything of itself that was of SI:<1. Then e may ascend to S2, retaining eir SI:1 nature but adding an S2 superstructure on top of the SI:1 nature. Contrast ascend-transcend. Often however the dividing lines are not this well defined.
Transcendent Being - Text by M. Alan Kazlev An entity that is distinct from physical existence, whether considered ontologically, as a supernatural or supraphysical being, or soteriologically, as a being that is no longer a part of embodied existence or samsara. The existence of a transcendent being or beings (e.g. God, Buddhas, etc.) is central to many religious memeticities, but denied by physicalist memeticities.
Transcension Prediction - Text by Anders Sandberg and M. Alan Kazlev Given the huge population of the civilized galaxy, and the fact that ascensions and transcensions are moderately common and have been going on for thousands of years, many polities and civilizations have developed some fairly reliable methods for predicting the onset of one of these events. Often this is comparable to pre- and post-singularity efforts at predicting the weather (and a large transcendence event does indeed share some conceptual characteristics with a force of nature to those watching from outside at a lower S level).
