Ok so Powder toy needs some changes to make it more consistent and understandable. Devs, if you see, this post, I would really apreciate considering these changes (in order of urgency):

!. In fusion, instead of a partcile becoming a new element, have two particles in contact become one particle, as this would make the nuclear physics system much more internaly consistent.

2. When two particles fuse, have the result be of a lowered temperature. This may be less likely than the first, but this would account for the extra energy needed to create photons.

3. Unlimited temperature. This would allow creators, or you, to raise fusion fuel to temperatures where it can keep fusing, despite heat becoming photons and exiting particles, among other things. This would aloso open the door to extreme fusions that could create heavy elements like uranium, plutonium, iron, etc.

4. Instead of fusing noble into CO2, have it fuse into oxygen, which fuses into broken coal, or vica versa (noble fuses into oxygen which fuses into broken coal). This could take advantage of the unlimited heat as well. The reason for this is that when CO2 is taken up by plant, an oxygen is relesed. Given the structure of a hydrogen atom in this simulator and the byproducts of the reactions, it can be deduced that an atom of CO2 has one neutron and four electrons, while an atom of oxygen has one neutron and seven electrons. Where did the three electrons come from?

5. Oxygen and broken coal become CO2. Pretty straight forward.

6. All fire becomes smoke, smoke emits an electron (or neutron) and becomes CO2 (or broken coal?). This would allow wood created by neutrons to return to return to its original state when burned, instead of dissapearing.

7. heavier elements. Gold and titanium and others could be created by intense fusions, existing way beyond the current temperature limit.

If only one of these could be implmented, #1 would be my choice. Thanks for bearing with me.
