For questions that allow fanciful, creative or imaginative solutions based on or rationalized by real world science, but not necessary limited by real world science.

This tag should never be the only tag on a question, because this tag frames how a question should be answered, not the topic.

Are nuclear armed missiles effective weapons for spaceborne combat?
I agree with Nosajimiki's answer that a nuclear-armed missile doesn't need to penetrate a ship to destroy it.
