# Thread: From Energy to Matter, from Matter to Energy

1. 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.

3. I do realize their is subatomic particles that follow into play here. Those of which that allows us to go from massless photons to mass.

4. I think perhaps this question would be easier to answer, if we delved a little into what energy actually is.

Energy has always been a little confusing to me, capacity to do work in a dynamical sense.. but isn't energy of the same specie as space? if Energy and Space were created at the same time during the big bang? Wouldn't this mean that energy is actually a form of condensed space or I don't know highly packed space with no mass, but at some point it turns massive because it somehow finds order?

I'm sorry, I'm just trying to learn. It all seems awkward to me, classical physics made more sense to me than modern physics.

have a look at pair production, this is what you want.
