The Timeshaft Wormhole Transport System

1.             Spacecraft departs home star system, bound for target system, ten light-years away. Crew enters cryosleep hibernation and/or temporal confinement for duration of voyage.

2.             Spacecraft travels for fifty years at one-tenth light-speed, thus traveling fifty years uptime and a distance of five light-years.

3.             Spacecraft reaches timeshaft wormhole, midway between home and target systems. Captain is revived briefly to pilot ship through timeshaft.

4.             Both uptime and downtime ends of wormhole are guarded by Chronologic Patrol ships.

5.             Spacecraft drops through timeshaft and is propelled one hundred years downtime, into the past.

6.             Spacecraft emerges from wormhole, fifty years before its departure from its home system and one hundred years before it enters the wormhole. Captain returns to temporal confinement.

7.             Spacecraft once again travels fifty years at one-tenth light-speed, again traveling fifty years uptime and five more light-years.

8.             After traveling for one hundred years shipboard time, spacecraft arrives at target system a few days or weeks after departure in objective time. Crew is revived from one-hundred-year hibernation to find less than a month has passed.
