the animation is from wikipedia's page on tachyons. the grey sphere is the particle moving faster than light approaching a given location on the graph. Then when the particle is in a given location, or when it would be calculable rather, it would be seen as splitting and going back where it came from as well as towards where it is heading.
i get it now, thanks

it's really interesting. i wonder how energy can be factored into that. seems like maybe there would have to be some sort of anti-energy driving the split part backward.
