In GR, there is said to exist a fabric of space-time, and gravity is the warping of the fabric of space-time. Since GR is simply an extension of SR, the fabric of space-time should exist for both, then, both relating to the same universe and all, right? So could the fabric of space-time be considered the mechanism that physically produces length contraction and time dilation in SR? Why or why not?
If not, why do length contraction and time dilation occur, and why isn't the universe Galilean? Also, what is the fabric of space-time?
