Travel on the fly in the intergalactic space between galaxies, and are much more technically demanding than even interstellar travel, and current technical conditions, is considered science fiction.

The space travel between galaxies is intergalactic travel. Travel to galaxy is impractical and is considered as science fiction. The available means of propulsion required to become advanced far beyond what is currently thought possible to engineer in order to bring a large craft close to the speed of light. While it takes light approximately 2.54 million years to traverse the gulf of space between Earth and the Andromeda Galaxy, it would take an arbitrarily short amount of time for a traveler at relativistic speed due to the effects of time dilation; the time experienced by the traveler depends both on velocity, being anything less than the speed of light, and distance traveled |
