well, if characters were to survive after an explosion and getting sucked to space, space battles would have no tension at all. not when force users are the pilots at least.
well, when you have something powerful like the force involved, i don’t see a solution other than sometimes using the power (because our space stories need a bit of ‘that was kick ass!’ sometimes) and sometimes conveniently not using the power. Seems to me like that has always been the case, except for perhaps ANH, where the force was just new and not as well explored as in the later movies.
and the kanan example shared above lasts for basically 5-10 seconds, and you can clearly see that he was almost, well, freezing to death already. i was under the impression leia was floating in space for a couple of minutes at least.
my impression was more like it was maybe 15 seconds.
