Reaching relativistic speeds in minutes to hours and covering interstellar distances in days to weeks as proposed in the abstract seem to not be compatible - wouldn't a relativistic speed mean we'd need 4ish years to reach another star?
> Such a craft accelerating at a constant 1000g for half of the trip and decelerating at the same rate for the remaining half would reach Proxima Centuri within 5 days’ ship time due to the fact that it would have been traveling at relativistic speeds for most of the trip (Figure 7B). However, for those of us on Earth, or anyone on Proxima Centuri b, the trip would take over four years.
