Alright, i have been coding this Python simulation of the powdertoy submatomic chain-raction with this information https://powdertoy.co.uk/Discussions/Thread/View.html?Thread=14196 and i have finally got to a useful result. The 200 lines of code pretty much resume the basic atomic particles (neutrons, electrons, hydrogen, ect) and their fusion processes. With this i can do a simulation to see what kind of energy is produced. I have to say it's pretty impressive.

The only dissimilar thing with powdertoy is temperature and pressure; i have coded it so every fusion increases pressure by 0.1; and that temperature increases by 100 every step so that we can see the next step in fusion. It gets REALLY computationally intensive; it will be instant until the 15th; then get exponentially longer.

If you guys are interested; i can post the code and the plots that i made with python to illustrate those things; i will also tweak it further so we can get fancy CERN-like plots.

EDIT: Pastebinning this; ayaye! Go to this link to see the whole print-out. The plots are hidden in the 8th post of the thread.

Basically the most interesting part is these 3 iterations. This is where the threshold for noble gas fusion is crossed and you see a big number of fusions who multiply exponentially.

 And on the following steps the curve shoots straight up; lagging up the computer. The last, 25th iteration takes maybe 1 minute to complete.

Thats done. Re-sized. Sorry; your forum code is weird; i'm not used to it..

Done. Here is the code for all interested http://pastebin.com/0LAe0gsN
