STANDARD TIME DILATION TO AC

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 hour × 60 sec min = 86,400 sec day If a vessel can g-force accelerate for an entire day, it will achieve a very high velocity. 9.8065 m sec × 86,400 sec day = 847,281.6 m sec Conveniently convert into 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.) TE further converts into AUs per day. 847.28 km sec × 86,400 sec day × AU 149,597,871 km = .489 day (Since planetary distances are typically measured in Astronomical Units (AUs), approximate value of .5 AU/day is very convenient.) Finally, TE converts to percent light speed per day as shown 847.28 km sec × c 299,792.458 km/sec = 0.2826%c = Δ (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 (Δ), consider the daily remainder (Rc): 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 km/sec) is fixed regardless of observer's speed.  Thus, Earth observer and vessel observer both observe c as same value even though Earth observer measures 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. VShip = c[1 - Rct]  To obtain velocities as AU/day, a convenient measure for 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 one year of g-force acceleration: VShip = 173.145 AU day × [1 - .997174365] = 111.513 AU day = 64.4%c 4) Cruise for several years 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 orbit and even land on objects in Alpha Centauri system. Thus, TE envisions vessel again powering the propulsion system to reverse the propulsion vector; thus, the high energy exhaust particles would flow in the direction of flight to decelerate the vessel. AXIOMATIC: Decelerating at g-force should take same time/distance as accelerating at g-force. Thus, TE assumes the voyage's final year would consist of g-force deceleration for the same distance (.38 LY) as the initial year of acceleration. 6)  Partial Time Dilation Simply calculate time dilation during cruise portion of voyage. Cruise Time can be expressed as normal time and relativistic. Normal Time At vessel velocity of 64.43%c,  Earth bound observer measures 1.55 years  for each LY of cruise distance. tCru=dCru/VCru tCru=3.56 LY÷.6443c = 5.523 years Relativistic Time 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.  Therefore, Thought Experiment (TE) decided to approximate acceleration's time dilation by averaging velocities.  Thus, following text discusses different methods to average vessel speeds. (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 =  .6385c + 0 2 =  .31925c Use above velocity to grossly approximate dilated time: tr = t √(1 - dc2) = 360 days √(1 - .319252) = 323.3 days This method indicates some time dilation, but TE seeks more precision. 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, V180  + V0 2 = 0.3983c + 0 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.

Each successive 45 day interval has a higher average vessel velocity. Each successive 45 day int;"> 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. Total tr =  Accel:tr + Cru:tr + Decel:tr For example, consider again the g-force journey  to the Alpha Centauri system. ACCELERATION PHASE Normal Acceleration Time Earth bound observer watches  g-force vessel accelerate  for 365.25 days to attain 64.43%c and travels .38 LY. Given: tAcc = 365 days Relativistic Acceleration Time Ship bound observer  measures duration of 330 days.(0.9 years). Rc = (1-Δ) = .99717 tTtl =Σ1day ×√(1-(1- Rct)2) CRUISE PHASE Normal Cruise Time At vessel velocity of 64.43%c, Earth observer measures 5.52 yrs  for 3.56 LY of cruise distance. tCru=dCru/VCru tCru=3.56 LY÷.6443c=5.52y Relativistic Cruise Time Due to relativistic effects, ship bound chronometer  measures: 4.22 yrs during cruise phase. tC-r= tCru×√(1-VCru2/c2) tr= 5.523 yrs×0.76 = 4.22 yr DECELERATION PHASE Normal Deceleration Time Earth bound observer watches g-force vessel decelerate for 1 yr (365.25 dy). tDec = tAcc = 365 days Relativistic Deceleration Time Ship bound observer measures duration of 0.9 years (328.7 dy). tD-r= tA-r TOTAL TIME FOR TRIP Total Normal Time tTtl = tAcc + tCru + tDec tTtl = 1.0yr + 5.52yr + 1.0yr tTtl =  7.52 yr  Total Relativistic Time tT-r = tA-r + tC-r + tD-r tT-r =  0.9yr+4.22yr+0.9yr tT-r =  6.02 yr 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 tCru   =   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 much quicker then the total 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). tAcc-Rel= tDec-Rel tAcc-Rel =  425.97 days = 1.166 yr = tDec-Rel Use the final dilated day factor (0.65373) to determine vessel observed cruise time. tCru-Rel = tCru × √(1-VCru²/c²) tCru-Rel =  4.0 yrs × 0.65373 = 1.166 yr = 2.62 yrs Finally, compare Earth observed times vs. Vessel observed times for 500 days of g-force acceleration. TOTAL TRAVEL TIME FOR 500 DAYS OF G-FORCE Total Normal Time tTtl =  tAcc + tCru + tDec tTtl =1.37yr+4.00yr+1.37yr tTtl =  6.74 yr  Total Relativistic Time tT-r =  tA-r + tC-r + tD-r tT-r = 1.17 yr + 2.62 yr +1.17 yr tT-r = 4.96 yr
