According to special relativity, the concept of time dilation occurs when objects are moving relative to each other at significant fractions of the speed of light. In this scenario, Twins A and B are departing from Triplet X at the same speed, and they are reaching space stations C and D, respectively. Since they are moving with the same speed in opposite directions, their relative velocity to each other is zero, and thus, there is no time dilation effect observed between them.
In special relativity, time dilation occurs when there is relative motion between observers. In the classical twin paradox, where one twin stays on Earth while the other twin travels into space at a high speed and returns, the traveling twin will experience time dilation and age less than the twin who stayed on Earth.
However, in your scenario, both Twins A and B are moving away from each other at the same speed. They will observe each other's clocks to be running at the same rate because there is no relative motion between them.
So, according to special relativity, A's clock does not run slower than B's clock, and vice versa, in this particular scenario. Both Twins A and B would perceive their clocks to be running at the same rate as they travel away from Triplet X towards their respective space stations.
