A while ago I had created a thread here about whether or not it was correct to say that elements and other forms of matter (elements being the building blocks) are ordered forms of energy.
Well building on that.. is it also correct to think that because of E = MC^2 you can go from matter to energy in a nuclear reaction releasing energy, however.. it would be also possible to go from energy to matter in an opposite circumstance.
For example,
I see it as an explosion, release of energy, increasing entropy of each system or photon. Contrary however, if those photons were forced to collide at high enough frequency and amplitude, in a dense environment, with the right collision it could produce matter.. a more ordered from of energy (less randomization).
Please forgive me if I'm wrong, I'm just trying to make sense of what I'm learning.
