If nobody shows up at the convention, then there is no hope for time travel, unless nobody saw the notes, because the people from the future, not matter what time they're from, will come to the same day and time. It doesn't matter if they're from 100 years from now, or 1000 years from now. They would all still end up here on the day of the convention. So if nobody comes, then there is no time travel at all. But once again, that is only if nobody found the notes. I hope that what I said seems right.
