Essay talk:E=mc2 explained

Math mode

You should write mathematical equations in math mode. The code is basically LaTeX. For example, $E=mc^{2}$. Nerd (talk) 16:05, 12 August 2018 (UTC)

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)

Atomic nuclei heavier than iron-56 can form in stars in energy-absorbing processes, but not in normal nucleosynthesis. Thus such a common heavy isotope as zirconium-90 must form in such a process as a collision of stellar remnants and then be released in some. Stellar remnants include mostly white dwarfs. In such an instance, energy is transformed into matter.

E=mc^2 is c squared and not twice c. m c-squared gives the coefficients of energy, as mass x distance-squared/time-squared. That is also work, as force multiplied by distance.Pbrower2a (talk) 20:13, 26 September 2021 (UTC)
