Science fiction writers, on the other hand, continued to use them, perhaps because they provided a handy way to move their characters around in

We have no idea at the present time how we would do this, but we do know that it is important to try to understand how these tiny quantum worm

Alexander Goebel,Sebastian G. M. H?ndschke only a few years ago were unimaginable. Yet, strangely, we are still not certain that time travel is, in fact, possible. We do know, though, that time tunnels—regions where space and time are twisted into wormholelike tunnels—are possible. Black holes have such tunnels associated with them. But unf
