This question already has an answer here:
Consider a man who is 1 metre in width and is running (at relativistic speeds) towards a pothole in the ground which is also 1 meter in width.
In the reference frame of the man it appears as though the pothole is moving towards him and as a result should shrink in size and therefore he will run over it.
In the reference frame of the pothole it seems as though the man is running towards it and so should shrink and then fall through the pothole.
How would one resolve this apparent contradiction as it is not plausible that the man will fall through the pothole in one reference frame and not fall through in another.
