TIme Travel Unlikely

So say the experts.

A traversable wormhole could be used for either travel from one point to another, or from one time to another. Unfortunately, according to the paper, quantum effects are necessary for the construction of stable traversable wormholes. This would cause the wormhole to behave unpredictably; you might not know where (or when) you would come out. Wormholes and time machines cannot be both predictable and stable.
