I'm a big fan of the Metroid prime games. I was reading about the technology in that universe and found I couldn't find anything on how they achieve faster than light travel. Is there anything saying or even hinting on the method in the games or mangas that I just haven't found?
(which apparently exists outside of our normal three dimensions), in order to travel between star systems and even extra-galactically on occasion.
This transit isn't instantaneous, and different ships travel at differing speeds. Federation 'recon' ships are evidently substantially faster than those from less-developed races.
Ships tend to have large engines that emit a bright plume when in motion, but it's not clear whether this is involved in FTL travel, or just intrasystem travel (e.g. after FTL travel has concluded).
Apparently a particular substance, referred to as Afloraltite, is involved in space travel and used extensively by Federation 'caravans' carrying food and other goods around the member planets. This presumably is a fuel source since it needs to be renewed constantly. There's no indication of whether this substance is needed for FTL travel.
We also have a diagram of Samus' ship from the Captain Nintendo comics. These show that her ship has separate drive systems for atmospheric, sublight, and hyperspace flight.
