Explosions don’t happen in vacuums, though, so I guess a good edit would just erase all of them.
I understand what you mean, though.
To be fair there are bombs falling in space in The Last Jedi
There is artificial gravity within the bomber that propels objects with a downward force. Once the bombs exit the ship and enter zero gravity, the momentum created by that downward force is enough to propel them toward the Dreadnought below them. Yes, Star Wars is not the movie for you if you like hard science, but of all the physics-bending things you could point out in the franchise, this is one of the things that actually makes sense.
