Could anyone (especially those who've read the series cuz' I didn't read the series yet) help me understand how the Jump Tech in  C. J. Cherryh's Alliance-Union universe work? I stumbled across a fandom page about it ( https://alliance-union.fandom.com/wiki/Jump ) and being confused on the time dilation part. I thought time dilation only applies for subluminal travel?
