Heh heh. Well, whatever Thorne says will be accurate, but like his friend Hawking he will be sensationalizing it. But the idea of getting caught in a vortex to affect exactly the spacetime your former self is in, well, science hasn't figured that out yet, but it's routine for the spiritual realm. So perhaps the effects are "too good" for what science knows now. The time dilation was "all right" but by my standards "all right" means at Planet of the Apes level.
