Question

What does nuclear fission have to do with the birth of stars?

Answer 1

Answer: When light element atoms are crushed under enough pressure for their nuclei to fuse, a star is formed. All stars are the consequence of a balance of forces: gravity compresses interstellar gas atoms until fusion reactions begin.

Step-by-step explanation:

Answer 2

Fission is the process by which large nuclei (like Uranium) split apart releasing energy. Fusion is the joining of nuclei to make larger nuclei, with the release of energy. A ball of contracting interstellar gas becomes a star like the Sun when fusion reactions start in its center. Then, we say "a star is born."
