space-17-exam-07. Explain (Physics only) Describe how a supernova can leave behind a black hole if the remaining mass is large enough for black hole formed after collapse. Use scale focus words: distance size universe galaxy solar stellar planetary cosmological hierarchy scale.

space-17-exam-07: A strong answer says that (Physics only) Describe how a supernova can leave behind a black hole if the remaining mass is large enough in The life cycle of a star. For black hole formed after collapse, name the relevant object, stage, motion or evidence and connect it to the learning objective. Star life cycles depend on mass: nebula and protostar stages lead to main sequence, then lower-mass and higher-mass stars follow different final pathways. Finish by separating the idea from a misconception such as planet versus star, moon versus satellite, orbit versus rotation, or galaxy versus universe.

This exam response follows a precise chain: identify the Space Physics context, explain the mechanism or evidence, and protect the concept boundary. The scale focus makes this item distinct while anchored to The life cycle of a star.
