It just came to my mind and i quickly thot of giving it a name like the famous grandfather or the twin paradox :D ..but cant find any :(
Imagine a wooden wheel spinning somewhere in the space. It has reached the speed of light i.e every particle on its outer rim is traveling at the speed of light. The speed is lesser for the inner particles and goes on decreasing as we reach the center of the wheel. Speed of the particle at the center is zero. Thus time has virtually stopped for the outer particle while the one at center is aging fast. Difficult to imagine since its a single body with all the particles connected. Even if we are able to imagine we cant tell the age of the wheel as whole, can we?
