It would certainly solve them problem of them physically traveling immense distances.

Although one of James Clark Maxwell’s field theories suggests that it is possible to step from any given point to another instantly. But that and 196 other equations were discarded by Oliver Heaviside to come up with 4 vector equation that describes everything we know about electricity and magnetism. What if, some were else, those same equations were not discarded and interstellar space ships are not need to travel from one solar system/galaxy to another?
If that theoretical possibility were proven true somehow, it might alter my position on physical interstellar travel. Right now, there's no real evidence that the laws of physics in one part of the universe differs from what we can observe here. As Scotty used to say all the time on Star Trek, "Ya just can't change the laws of physics!"
