I found the source of my confusion. The post I replied to stated, "I don't know how much time would have passed on Earth though." You stated I calculated "how much time would pass on Earth." The OP was wondering, "if a person on a ship visited a star 100ly away, how much time would have passed on Earth when they returned?" However, the OP was wondering about time frames in terms of a warp drive, rather than a conventional almost-light-speed drive. Take my upvotes. :-)
