Rehashing Time Travel
You have already written the story that you will submit to this challenge. In fact, my decision about the winner has already been made. All of this has already happened very soon in the future, and all you need to do now is satiate the time continuum by copy-pasting your entries from the future into the present.
The media will be/is being/has been all over the recent theory that the Large Hadron Collider is a time machine. You will have read more about it at the link you already saw at the bottom of this page, and I’m sure that it sparked your interest, or you would not have entered this challenge.
So dig around in your future brain, and pull out a time-travel themed story that you posted here. I know I have already read it then, but trust me, I will want to read it for the first time as well!
