Ok, now suppose you accelerate the stick closer to the speed of light, towards my barn.

Because of relativity, objects accelerating towards you are smaller than they would if they were stationary. If I'm in the barn and the stick is going fast enough, too me it could be smaller than the length of the barn.

If I close the door once the stick is fully inside the barn, What would happen to the stick. Does it expand? Can it really fit in the barn?

This was from a physics exam back in college đŸ˜…
