Essay talk:E=mc2 explained
The sun does the same but in reverse?
Well, it is true that in the sun, hydrogen atoms are fused to helium atoms. Fusion instead of fission. Is that what you mean? But it is not "the same but in reverse". Hydrogen atoms are very very stable. Most of the universe is made of hydrogen atoms. Uranium and other heavy atoms are made inside stars! Gill110951 (talk) 10:20, 20 November 2020 (UTC)
