Isn't that what birdbrain wrote on the bomb?
If you watch the Netflix show FreQuency it is about a girl detective that can hear her dead father over an old radio. They both give each other information so he can avoid his death but it creats different timelines. Knowing what will happen in the past effects the future , future proves past. Kind of like the Q drops they were of one timeline, but knowing this information changes the timelines slightly moving forward. It is interesting to watch in context of Q drops.
