I was thinking about time travel. Imagine you're transported back to September 10, 2001.
I assume you'd want to warn the government about the attacks that are about to happen. But how would you do it? How could you warn them in a way that would have them take notice, rather than ignore you, or write you off as a nut?
And as a secondary question, is there any way you could provide enough information without having officials think that you must have been in on it?
Sometimes I think time travel is more trouble than it's worth.
