I can say with absolute certainty that there will be a massive and devastating earthquake and an even more dangerous asteroid impact... within the next 100,000 years. The problem is that few people will want to read a story like that... well, at least outside the fields of tectonics and orbital mechanics. Personally, I believe they will happen much sooner, but it still may not be within my lifetime... I'd rather they not be within my lifetime, TBH.
