I don't think that is necessary, what do you have in mind?
- weard_beard 4y agoThey mistook a diagram in the video showing flow of time for velocity. You can go there and back again in space at faster than light, but your local time bubble runs forward in each case. No traveling back in time. An external observer sees you traveling back in time the way we see gravitational lensing but your personal frame of time marches forward.
