space-65-exam-06. Explain (Physics only) State that the Sun is one of many stars in the Milky Way galaxy for Milky Way compared with the universe. Use mechanism focus words: cause force gravity fusion radiation expansion attraction orbiting mechanism.

space-65-exam-06: A strong answer says that (Physics only) State that the Sun is one of many stars in the Milky Way galaxy in Our Solar System. For Milky Way compared with the universe, name the relevant object, stage, motion or evidence and connect it to the learning objective. Red shift means light from distant galaxies has increased wavelength; together with cosmic microwave background radiation it supports an expanding universe from the Big Bang. 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 mechanism focus makes this item distinct while anchored to Our Solar System.
