摘要：
Spacetimes of general relativity containing closed timelike curves (CTC) are usually dismissed as non-physical. However, it is now known that CTC may appear in spacetimes modelling simple laboratory experiments, and two such experiments are described in this essay. We therefore need a realistic interpretation of CTC. I suggest that a region containing CTC may represent a new type of singularity, called a torsion singularity.
