While this is generally interesting, there is a pet peeve that prevents me from upvoting: there is no way, short of a humanity-reset button (which is exactly what happens in this SCP, evidently) in an Ennui-5 scale that something like this could remain hidden. Several hundreds of years of astronomical development, written register, background cultural impact and beyond, erased by the Foundation? Edit: I mean, even constellations? Damn. Just damn.
It strains my credibility. A lot. I mean, one thing is to contain information about the events that transpire on a specific year in history; the other is to contain all data and memories of events prior to that year. Saying "woah, reality reconfiguration event" is only going to strain my credibility even further… but that only has to do with me being a sucker for both concepts and not wanting to see them abused.
Finally, a secondary problem. Keter? It should be considered Neutralized at this point, right?
Otherwise, I can understand why people would like (and love) this concept. I don't dislike it myself, it's engaging and all. But neutral vote. Sorryyyy :_(
Edit Edit: And yet another problem, this one is fridge logic. You are a hyper-advanced society of Utopian amphibians that have the means to swap your planet with other planets across the cosmos. What do?
Why, choose an inhabited planet to do so!
That's something only an absolute asshole of a civilization would do, imho. Not to mention that if you have this kind of power you could be using to move the population, spending a lot less energy in the process, but the tech issues underlying to the item itself are irrelevant for this article, that focus on the consequences of the swap.
