Time Traveling Hey guys, so I'm stuck trying to come up with a realistic method of time travel that would be not only suiting for the story but believable to the reader (even though time travel is a rather implausible phenomenon.) Here's a general gist of the plot of the story: A boy whose a senior in high school is an intern for a very inactive hospital (meaning they don't get many patients.) Therefore the hospital usually gets patients with petty injuries (such as falling down steps, etc.) and the doctors are very lackadaisical about their patients. An example of this would be a girl who occasionally checks in for unknown mysteries that come about (such as pesticides somehow showing up in her system.) The doctors attempt to crack the case very carelessly and eventually give up. The boy learns later that he actually attends the same school as the girl and begins an awkward relationship with her that grows in to something much more meaningful. He puts together pieces of clues that leads to the assumption the girl is actually trying to kill herself, or cry out for attention (but failing to do so.) One weekend, he is certain that the girl must be suicidal and heads over to her house late at night to confront her about it. Little did he know that the girl was actually planning on hanging herself that night had he not come. She eventually spews out all her emotions and tells the boy about how she had lost her older brother in a McDonalds robbery about a year ago (the very same robbery and killing that the boy had witnessed when he went to get his daily coffee) and has been emotionally wrecked living with an Uncle who parties frequently and no one to take care of her, and also having to deal with the unfortunate consequences that resulted from her brother's death (her first "therapist" turned out to actually a rapist who filmed kiddy porn, etc.) The same night they go out for ice cream and an incident happens when the girl is ran over by a drunk driver and dies on the way to the horribly untrained hospital. From that point on the boy somehow acquires knowledge accidentally (or learns) of controlling time thus allowing him to travel back in time. I don't know if I should add hints throughout the story (like his physics teacher lecturing about time travel and him becoming fascinated by it) or if he should somehow acquire some sort of unnatural super power. But somehow, whether it be accidental or on purpose, he needs to travel back in time the very same day of the robbery and take the shot for the older brother, to prevent creating an unlimited amount of tangents in quantum realities and filling the universe with more mass than it can handle (since time travel is a dangerous thing.) So he kills himself not only to save two lives, but to save the universe as well. sorry for such a long post, i just thought i'd give as much information as possible so you guys don't get confused or anything.
