Ves thought that was the end of it. Something flung from a ship while traveling in FTL space rarely if ever made it back to reality.
The higher dimensions bore only a loose connection to the material realm. Time, distance direction, mass and energy behaved very differently in these dimensions!
Many races including humanity took advantage of the properties of the higher dimensions to travel faster than light.
Technically, the ships weren't traveling faster than light in the higher dimensions. It was just that distance was getting more compressed the higher the dimensions went, which allowed for a slow-moving ship to reach an incredibly distant destination in a reasonable amount of time.
