Not really my usual territory (I'm more into the earth mysteries side of things) but this did catch my attention. I remember the 2019 UK power cut and thinking it was odd timing given what was happening in Parliament that week. Could be confirmation bias though - we notice the ones that fit and forget the dozen that didn't.
What's the actual data here? Like has anyone mapped this out properly or is it more of a pattern people have spotted through observation? Genuinely curious whether there's a list somewhere of the incidents you're thinking of, because without that it's hard to know if we're looking at a real correlation or just our brains doing what brains do.
Also worth asking - who would even benefit from a blackout before an announcement? Chaos doesn't usually serve whoever's making the announcement. Unless the blackout IS the announcement in some way, which is a different theory entirely.
