I’m new an I admit I haven’t read all 109 pages of this thread. So apologies if this was already said/discussed. But I have three points about things that don’t make sense in The Last Jedi.

Surviving for a minute or two in vacuum doesn’t require any Force powers, most humans are capable of it, however, with serious physical injuries. Pulling yourself towards an object in zero gravity and vacuum requires a very, very, very small amount of Force use, probably a lot less than pulling a lightsaber out of the snow.
Spaceships in Star Wars have artificial gravity. If I drop an object within a spacehip, say, a cluster of bombs, it will fall towards the bottom of the spaceship. If it falls out of the spaceship, it will already have an initial velocity that will continue to propel it along its trajectory (albeit without any acceleration).
Spaceships in hyperspace, at least according to Wookiepedia/Canon, are in another dimension. Supposedly, they cannot interact with objects in “realspace”. However, there is a second or so when they are transitioning from realspace to hyperspace. During this transition, we see elongated stars aboard the spaceships, and the elongated image of the spaceship accelerating suddenly from outside the vessel. Maybe, if you can calculate the exact time and realspace distance required for this transition, you can turn your spaceship into a devastating weapon that smashes into its target at the end of this transition period, when at least a part of it is still in realspace, but is already accelerated to relativistic speeds. However, this is difficult to weaponize, because you have to get relatively close to your target and be very exact in your calculations.
