Cool subject. Firstly, I don't think time travel has anything to do with speed -- that's baloney science invented by the creators of Superman, I think. The real theory is not that matter becomes energy at lightspeed. It's that any object having mass, such as an electron, becomes infinitely massive as it approaches lightspeed and requires infinite energy input to continue accelerating. Can't do it, in other words. But it's just a theory. Anyway, chasing light rays is just going to bring you an image, right? not something you can interact with.
Loops and branches in the timeline are a convenient way to imagine travel by whatever means. Once you leave the normal timeflow you create a branch that will never permit you to return. Travel again and you're on a branch of a branch, and so forth.
