Spaceship parameters

This document contains the results of a calculation based on a discussion in a posting the usenet newsgroup sci.physics.research The title of the posting is: "How to test length contraction by experiment?" For the general discussion read this:!topic/sci.physics.research/JesOwTVZ-t4

T #n r v accel circumf path length
C1 0,11000,21513,537850,537 1,354135,367
C2 1 101,000 6,283 39,478 6,283 62,832
C3 10 14,642 2,916 1,83229,164 29,164
The table shows the results of three spaceships: C1, C2 and C3
  1. Column 1 shows the name of each spaceship.
  2. Column 2 shows the revolution time T in years of each orbit.
  3. Column 3 shows the number of orbits #n for each spaceship.
    The number of orbits is selected such that the total travel time for each spaceship is 10 Years relative to the frame of the earth.
  4. Column 4 shows the radius of each spaceship. The radius is calculated based of Keppler's third law. See:
    In this particular case r^2= T^3 or r=T^(2/3)
  5. Column 5 shows the speed of each space ship i.e. v = 2pi*r/T
  6. Column 6 shows the acceleration of each spaceship i.e. alpha = v^2/r
  7. Column 7 shows the circumference of each orbit i.e. 2*pi*r
  8. Column 8 shows the total path length i.e. circumference * #n
What the table shows is that the spaceship closest to earth has the higest speed, higest acceleration and the longest pathlength.
If all the spaceships have a clock based on lightsignals than the clock of C1 will run the slowest relative to the clock in the frame of the earth.
