8) DECEL. TIME DILATION
9) TOTAL DILATION
SUMMARY

Previous chapters have discussed G-force accelerations of various durations.EXAMPLE-1:  100 days of G-force enables a cruise velocity of about 25%c.EXAMPLE-2:  G-force propulsion for a year achieves a cruise velocity of about 65%c.  (NOTE: Further discussed in "Standard" Time Dilation to AC.) Thought Experiment (TE) assumes that inherent fuel limitations would not enable a vessel to G-force propel for much longer than one year.EXAMPLE-3:  HOWEVER, Interstellar Snowballs (huge spheres of ice sent to refuel star bound ships) might enable an interstellar vessel to G-force accelerate for as long as 712 days to enable a cruise velocity of 86.7%c.  At such a speed, vessel observers would measure time at half the rate as an Earth bound observer (due to relativistic time dilation).

1) G-FORCE FOR ONE SECOND
Let an object free fall for one second near Earth's surface, and it will gain a velocity of about 10 m/sec (actually 9.8065 m/s). Let it continue free fall for a 2nd and 3rd second, and velocity will become about 20 m/s and 30 m/s respectively.  SUMMARY:  Velocity will increase about 10 m/s for every second of free fall.
2) G-FORCE FOR ONE DAY
One day has 86,400 seconds

If a vessel can g-force accelerate for an entire day, it will achieve a very high velocity of 847,281.6 m/sec.

Daily Difference (Δ). After one day of g-force propulsion, vessel achieves a small portion of light speed. Thought Experiment (TE) calls this percentage the daily difference.
Δ= 0.2826%c
3) G-FORCE FOR 712 DAYS
Phase 1. Accelerate for 712 days at g-force. This achieves a high cruise speed to shorten flight duration and also simulates gravity for contents and occupants. Since g-force comes from particle flow leaving aft of vessel, occupants feel a gravity like force likely from decks (axial planes intersecting the longitudinal axis). Thus, "up" is toward forward end of vessel which is pointing toward AC, our destination.
Remainder. In contrast to the daily difference, TE designates the daily remainder (Rc):
Rc=c - Δ = .997174c
as the gigantic portion of light speed not yet achieved after one day of g-force.
Einstein tells us in his Special Theory of Relativity that light speed (c=299,792.458 k/s) is fixed regardless of observer's speed.  Thus, Earth observer and vessel observer both observe c as same value even though Earth observes continuously, increasing velocity of g-force vessel.
TE reconciles this paradox via following exponential which calculates vessel velocities to ever approach c but never attain it.
VShip=c[1 - Rct] 
To obtain velocities as Astronomical Units per day (AU/dy), a convenient measure for g-force interplanetary travel, restate value of c:
c=299,792.458 km
sec		×86,400 sec
day		×AU
149,597,871 km		=173.145 AU
day
EXAMPLE:  After 712 days of g-force acceleration:
VShip=173.145 AU
day		×[1 - .997174365]=150.060 AU
day		=86.7%c
4) CRUISE FOR SEVERAL YEARS
In this example of an interstellar profile, g-force vessel accelerates for 712 days to achieve a cruise velocity of VCru  = 86.7%c.  To conserve fuel, vessel then terminates propulsion and maintains earth like gravity via centrifugal force by spinning vessel about its longitudinal axis at carefully planned angular velocity.
Phase 2. Cruise for 909.5 days (about 2.5 years) at .866c. TE assumes that even with augmentation from snowballs, vessel must still conserve fuel.  Thus, vessel must "cruise" at constant speed for middle portion of flight; without G-force acceleration, flight planners must determine another way to simulate Earth gravity. This is done by spinning craft in such a manner to produce centrifugal g-force against inside of outer hull. Thus, from Phase I to Phase II,, ship must transform from living area on decks (floors perpendicular to exhaust flow of particles from aft end of vessel) to living area on hull. Thus, occupants must quickly adjust from decks being floors and hull being wall to decks becoming walls and hull becoming floor. Thus, "up" is toward the central, longitudinal axis of the cylindrical vessel. (While Phase I's up would be parallel for all occupants, Phase II's up would differ for every occupant.)
5) REVERSE G-FORCE FOR FINAL 712 DAYS
During the cruise phase, the vessel makes excellent time due to its relativistic speed (86.67%c = 259,818.131 km/sec); however, the g-force vessel must slow down (to a few km/sec) to approach and orbit objects in Alpha Centauri system.
Thus, TE envisions vessel again powering the G-force propulsion system to reverse the propulsion vector; thus, the high energy exhaust particles would flow in the direction of flight to cause a decelerating effect.  It's axiomatic that decelerating at g-force should take same time/distance as accelerating at g-force.  Since the first year of g-force acceleration took 1.11 LY, the voyage's final year would consist of g-force deceleration for the same distance.
Phase 3. Decelerate for 712 day at g-force; ship must slowdown from enormous velocity (86.6% of light speed) to operational velocity required to maneuver around AC system. Thus, hull becomes a wall again, and decks once more becomes a floor. Of course, exhaust flow must point toward destination because the exhaust force must now counteract motion of vessel. (Of course, "up" once again points forward, but the forward end of vessel is now pointing toward Sol, our place of departure.)
6) CRUISE TIME DILATION
Since we assume an interstellar vessel travels at constant relativistic speed during the cruise portion of flight, it is a straight forward procedure to simply calculate time dilation during cruise portion of voyage.
Previous chapters provide procedures for determining distance during G-force accelerations.
For 712 days of G-force acceleration, TE determines distance to be 1.11 LY. For 712 days of G-force deceleration, TE assumes equal distance.  Since observed distance to AC is 4.38 LY, we assume cruise distance:
dCru = dTtl - dAcc - dDec 
dCru  = 4.38 LY -1.11 LY - 1.11 LY = 2.16 LY
Cruise Time can be easily expressed as both normal time as well as relativistic.
Normal
Time
At vessel velocity of 86.66%c, 
Earth bound observer measures 1.155 years 
for each LY of cruise distance.
tCru=dCru/VCru
tCru=2.16 LY÷.8666c = 2.495 yrs
Relativistic
Time
Due to relativistic effects, 
ship bound chronometer measures:0.5 yrs 
for each year observed by Earth.
tr= tCru×√(1-VCru2/c2)
tr= 2.495 yrs×0.5=1.25yr
However, cruise is only part of the interstellar flight, and time dilation also happens during acceleration and deceleration phases.

7) TIME DILATION DURING ACCELERATION
Computing time dilation for g-force acceleration more difficult because such velocity is ever increasing.  Thus, TE uses following technique to approximate time dilation for each day of acceleration.
Determine Spot Velocities. To determine spot velocities for end of each travel day (which TE also assumes as the initial spot velocity for next travel day), TE uses following formula as previously described.
VShip = c[1 - Rct] 
Determine Daily Average. To determine average velocity for each acceleration day, TE determines mid velocity.  Next, TE converts this average from AU/day to decimal light speed (c), designated as dc.
Convert vessel velocities from decimal light speed to/from AU/day with conversion constant:  c = 173.145 AU/day.

8) TIME DILATION DURING DECELERATION
Since TE assumes that acceleration duration equals deceleration duration, TE further assumes that corresponding time dilations are also equal.  
Determine Daily Dilation. Following diagram shows daily dilations after 365 days of g-force.  Of course, we assume that interstellar vessel can even accelerate well beyond 365 days as fuel permits.
9) TOTAL TIME DILATION
For total time dilation (tr-Ttl), consider relativistic time shrinkage during all three phases of interstellar voyage: g-force acceleration, cruise, and g-force deceleration.
