Einstein's twin paradox in Special relativity is about the space time fabric.

Explanation:

In the twin paradox it is believed that if a twin out of a pair is sent on a high speed rocket right after it was born and returns to earth some time later he will find that his sibling has aged more than he has.

This is because according to the theory of Special Relativity, time is slower when the speed at which one is going is fast and time can stop when one can achieve the speed of light as time and speed are relative to each other.
