Aside from the fact that sound doesn't travel in outer space... Spaceships shouldn't be able to decelerate by reducing engine thrust, or maintain the speed by a constant engine thrust, since there's no inercia to oppose any acceleration/deceleration. Am I correct?

Should be no sound, no normal acclelerates, explosions.. etc But You know... Hollywood made that way (Star Wars) and now everybody doing this way to make this more "real" and spectacular even it's not true Like explo when shooting at car's fuel tank, or someone flying 10 meters after hit with riffle
I think it should looks the same when You hit the balloon (more air-pressure inside than outside). So i think It'll be veeeery vast "explosion" without sound and fire, maybe veeeeery smaal fire but burn down/out so quickly that you wiil be not able to see it.
