Apparently, a wormhole is our best bet for a time machine

Though wormholes have never been proven to exist, these theoretical passageways through space-time are predicted by Einstein’s general theory of relativity.
… astrophysicist Eric W. Davis, of the EarthTech International Institute for Advanced Studies at Austin, argues that it’s possible. All you need, he says, is a wormhole, which is a theoretical passageway through space-time that is predicted by relativity.
“Time machines are unavoidable in our physical dimensional space-time,” David wrote in his paper. “Traversable wormholes imply time machines, and [the prediction of wormholes] spawned a number of follow-on research efforts on time machines.”
However, Davis added, turning a wormhole into a time machine won’t be easy. “It would take a Herculean effort to turn a wormhole into a time machine. It’s going to be tough enough to pull off a wormhole,” he told LiveScience.
That’s because once a wormhole is created, one or both ends of it would need to be accelerated through time to the desired position, according to general relativity theory. More.
Okay, okay, so we can’t go back in time twenty minutes and not be late for work or forward in time to cash our paycheque on Friday and make it back for today’s rent.
So, like, why does anyone care? Is this question of time travel in the same league as: If a tree falls in the forest, and there is no one around to hear it, does it make a noise? Fun but … Just wondering. Thoughts?
