TOTAL TIME DILATION


tr =t ×  (1 – dc2)
let dc=VShip/c
Time Shrinks
at relativistic speeds. 
Observers on very high speed vessels will measure time at a slower rate than "at rest" observers back on Earth. EXAMPLE: After 1 year of g-force propulsion, vessel velocity is 65% light speed (.65c). Then, let an Earth bound observer spend 1 day watching this vessel, observer on the vessel would measure a duration of only .76 days.

1) g-force for a sec. 
Near Earth's surface, let a material object free fall for one second, and it will gain a velocity of 9.8065 m/sec (about 22 miles per hour).
Let it continue free fall for a 2nd second, and velocity will become about 20 m/sec.
Velocity will increase an additional 9.8 m/sec for every added second of free fall.
2) g-force for a day 
One day has 86,400 seconds (= 24 hours/day × 60 min/hr × 60 sec/min).
If a vessel can g-force accelerate for an entire day, it will achieve a very high velocity of 847,281.6 m/sec  (= 86,400 sec × 9.8065 m/sec).
This velocity can be conveniently converted into several other equivalent values.

847,281.6 m/sec × km/1,000 m = 847.28 km/sec
(By comparison, typical asteroid travels around the Sun at 25 km/sec.)

847.28 km/sec × 86,400 sec/day × AU/149,597,871 km = .489 AU/day
(Since planetary distances are typically measured in Astronomical Units (AUs),
approximate value of .5 AU/day is very convenient.)

847.28 km/sec × c/(299,792.458 km/sec) = 0.2826%c
(After one day of g=force, vessel achieves a small portion of light speed.
Thought Experiment (TE) often calls this percentage the daily difference, Δ.)

3) g-force for a year
In contrast to the daily difference, the daily remainder:
(Rc = c - Δ = .997174c) 
is 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 which forever approach c but never get there.
c[1 - Rct] = VShip
To obtain velocities as AU/day, a convenient measure for interplanetary travel, restate value of c:
299,792.458 km/sec × 86,400 sec/day × AU/149,597,871 km = 173.145 AU/day
EXAMPLE:  After one year of g-force acceleration:
VShip = 173.145 AU/dy[1 - .997174365] = 111.513 AU/dy = 64.4%c
4) Cruise for several years
In this example of an interstellar profile, g-force vessels accelerates for one year (365.25 days) to achieve a cruise velocity of VCru  = 64.43%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.


5) Reverse g-force for final year 
During the cruise phase, the vessel makes excellent time due to its relativistic speed (64.43%c = 193,156.281 km/sec); however, the g-force vessel must slow down (to a few km/sec) to approach objects in Alpha Centauri system.
Thus, TE envisions vessel again powering on the propulsion system and reversing 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 .38 LY, the voyage's final year would consist of g-force deceleration for the same distance.

6)  Partial Time Dilation
Simply calculate time dilation during cruise portion of voyage.
Cruise Time can be expressed as normal time and relativistic.

At vessel velocity of 64.43%c, 
Earth bound observer measures 1.55 years 
for each LY of cruise distance.

tCru=3.56 LY÷.6443c = 5.523 years
Relativistic

Due to relativistic effects, 
ship bound chronometer measures:0.76 yrs 
for each year observed by Earth.
tr= tCru×(1-VCru2/c2)
tr= 5.523 years×0.76 = 4.22 yr
However, this is only part of the time dilation.

7) Time Dilation During Acceleration
Computing time dilation for acceleration and deceleration is much more difficult because g-force velocity is not static, it is dynamic.  Fortunately, it's reasonable to assume that dilated time for acceleration is likely to equal dilated time for deceleration.  Thus, following text focuses on computing dilated for g-force acceleration during first year of voyage.

(For convenience, round one year to 360 days for exercises a through e.)
a. Overall Average.
Determine g-force vessel's overall average velocity as shown below:
VFin + V0

2
= .31925c
Use above velocity to grossly approximate dilated time:
trt √(1 - dc2) = 360 days √(1 - .319252) = 323.3 days
This method indicates some time dilation, but accuracy is likely compromised.

b. Average 2 Halves. 
Divide acceleration duration into 2 equal parts,
Part 1 is days 0 through 180:  t0  t180.
Part 2:  t180  t360.
Average min and max velocity for each half,

2
= .19915c
V180  + V360

2
=0.3983c + .6435c

2
= .5209c

Compute time dilation for each half:
tr = t √(1 - dc2) = 180 days √(1 -.199152) = 176.4 days

tr = t √(1 - dc2) = 180 days √(1 - .52092) = 153.6 days

Sum the results.
Σtr = 176.4 dy + 153.6 dy = 330.0 days

To approximate time dilation, TE uses the average vessel velocity 
for each 90 day interval.
Each 90 day period shows increased shrinkage as velocity increases.

Sum these results
Σtr = 89.4 dy + 85.5 dy + 79.6 dy + 72.9 dy = 327.4 days 
for a slightly more accurate value of time dilation during first year of g-force acceleration.

Each successive 45 day interval has a higher average vessel velocity.

As each interval's average velocity increases, the corresponding time dilation increases (shorter period as measured by on-board observers).
If we accumulate total dilated time as shown, we can approximate total time dilation for the entire acceleration period, 360 days as observed from Earth.

e. Average 18 Parts
Greatly increase accuracy by dividing duration into eighteen equal parts

f. Average Everyday to 360 and beyond!!!
Greatly improve accuracy determining spot velocity for every day of g-force.  Vessel can even accelerate beyond 360 days as fuel permits.
Following diagrams show daily increments for an entire year, 365 days of g-force.

Convert vessel velocities from decimal light speed to/from AU/day with conversion constant:  c = 173.145 AU/day.




8) Total Time Dilation
For total time dilation, also consider relativistic time shrinkage during the acceleration/deceleration phases of voyage.

Final Note:
NOTE: LY = 63,241 AU; c = 173.145AU/day
Fuel permitting, interstellar vessels can attain higher speeds to further increase the time dilation effect.  For example, consider a g-force acceleration time of 500 days.
At 500 days (1.37 yr) of observation by earth bound observer,
a g-force vessel attains a velocity of 131 AUs/day (≈ 0.7566 c)
and a cumulative acceleration distance of 40,201 AUs (≈ 0.6357 LY).
This new acceleration distance changes cruise distance to AC:
dCru = dTtl - dAcc - dDec
dCru = 4.3 LY - .636 LY - .636 LY =  3.03 LY
Subsequently, new cruise time is observed:
tCru = dCru / VCru
dCru =  3.03 LY / 0.7566 c = 4.004 Yr
Earth Observed Trip Times are as follows:
tTtl =  tAcc + tCru + tDec
tTtl =  1.37 yr + 4.00 yr  +1.37 yr = 6.74 yr
which is even quicker then the earth observed trip time for 1 year g-force acceleration.
Vessel Observers would measure Dilated Times:
To determine dilated times for 500 days of g-force acceleration, extend the table to the left to 500 days. If one did this, one would determine at .7566c, a vessel observed day shrinks 0.65373.  Furthermore, 500 days of Earth observed acceleration time shrinks to 425.97 days of vessel observed acceleration time (assume same for deceleration times). 
tA-r = 425.97 days = 1.166 yrs = tD-r
Use the final dilated day factor (0.65373) to determine vessel observed cruise time.
tC-r = tCru×(1-VCru2/c2) = 4.0 yrs × 0.65373= 2.62 yrs
Finally, compare Earth observed times vs. Vessel observed times for 500 days of g-force acceleration.
