When a cannonball is fired in space, the absence of air resistance means it would travel indefinitely until acted upon by another force, unlike on Earth where gravity and air resistance significantly affect its trajectory. The impact of a cannonball in space would still be lethal due to its mass and velocity, but the sensation of pain would be influenced by the lack of atmosphere, which affects sound and pressure. The discussion emphasizes the importance of understanding physics principles such as inertia and momentum in both environments.
