In addition to the reciprocity and simultaneity failures of Special Relativity I thought I would add a bit in food for thought regarding the Velocity Addition Formula.

Given the case: Rest distance = 200 units.

1 - A<-----------(100 units) ---------------------->B = 0.866c

The relavistic affects are based on a gamma = 2.000. Meaning that time (clocks) tick at half the rate they did at rest and distance is cut in half.

2 - A<-----~82 units-------------C------~82 units--------->B ; where AC = -0.577c and BC = +0.577c;

AB according to the VAF = 0.866c.

3 - The problem is that relativists like you to see only one aspect of their theory at a time.

(1 above) A<--------------------------------------->B = 100 units

(2 above)..................A<-------------->B = 164 units

Both of course are 0.866c. Further in case 2 the actual situation is not so simple. You cannot disregard that A still sees C as moving at 0.577c which means that A only sees B moving away from C at 0.289c.

Distance from AC is therefore 0.8167 the rest distance (or time) and the affects at 0.289c is 0.9573.

A<---------~82 units--------------C---------~96 units------------->B = 178 units.

But the distance AB is less than A sees for A to C + C to B.

A<---------------100 units---------------->B

Now if I must travel less distance (0.5) and my clock ticks slower (0.5), then that would mean during the trip my clock would accumulate 0.25 as much time.

Hmmmm.
