1.   Fusion, the joining together of atoms, is the process that powers the sun, the stars and thermonuclear weapons.

2.   The fusion principle involves joining together the nuclei of two hydrogen atoms to form a nucleus of helium, the same reaction that powers the sun and hydrogen bombs.

3.   The Standard Model describes the world from the ground up, from the architecture of atoms to the reactions that power the sun.

4.   The sun is powered by fusion, and so are hydrogen bombs.

5.   They are created by some of the most basic physical processes of the universe, such as the decay of radioactive elements and fusion reactions that power the sun.

6.   Fusion is the process that powers the sun and stars.

7.   Fusion, the process that powers the sun, releases tremendous energy but produces far less radioactive waste than fission, the process behind the atomic bomb.
