I'm a noob in this lol, but a thought just cross my mind. If in nuclear fusion, we require high temperature to overcome the EM repulsion of nuclei, is it possible to bypass this and simply make use of the nuclear force, or color interaction which holds the nucleus together. Is it possible to amplify this color interaction so that fusion takes place instead of just holding it together. And also, if I'm not wrong, cold fusion has not yet have a theory behind it, could this be a possible theory? Also, its kinda off topic but I've got a question regarding beta decay. If. 3H (can't do superscript, its tritum as opposed to 3 molecules of hydrogen) ------>4He (again...) + e Why is it that in one side of the equation I've got one electron and the other I've got 3? I know that Beta decay causes neutrons to decay into a proton, electron and neutrino, which explains the presence of one out of the 2 difference in electrons. What about the other 1, where did it come from?
