Thinking of time as flowing etc does not mean time works that way.

Visualizations of a concept is one of the ways humans understand an object. Sure there are incorrect models, but we find the ones that fit our current empirical data until we get new data or have new ideas about ways to visualize them.

There's no way that we currently know how to go back in time, that is part of the debate. Because we only have equipment that lets us detect travel in a forward direction (timewise), that's the only info we have that's applicable.
To bring up a point though, I remember a philosophy class I took a few years back where the concept of time was brought up. When pressed for definitions and synonyms of time, I threw out 'change' because the only way we can actually detect the passage of time is through change. Now to give a nod to Pfhorte and abandon the timeline model and the conceptions it brings with it, could we not say that going back in time would be synonymous with resetting all elements in the world (or whatever space you wish to work in) back to a state so as to negate any change that had happened between then and the present?
Taking out all concepts of blackholes and timewarps, this seems essentially what we're trying to get at, an unaltered state at a point prior to our current state. In that case, does time travel still seem feasible?
Offtopic Q: Why is this thread in paranoia? Seems like it should belong in philosophy.
