Time dilation and length contraction are two aspects of the same thing - that the speed of light remains the same for all observers. We had this example before - if you travel to Andromeda at near the speed of light, seen from the outside, 2 million light years are travelled in 2 million years. From the inside, only a few light years are travelled in a few years time. Both reductions have to be present for the ratio of distance and time, which is near the speed of light, to be the same for both observers.
The fool hath said in his heart, There is a God. They are corrupt, they have done abominable works, there is none that doeth good.
