In response to your spoiler:

I specifically didn’t like that scene because it’s a massive departure from the lore of all the other films. If they could just do that, why haven’t both sides been doing that all the time? Is it supposed to be that this group is the first group to try this, with the tech that has been around for at least a few centuries? If they had all died in the process I’d be more ok with that, although that also seems like a departure from how hyperspace works in the other films.
