Hallo! Now I've noticed something about nuclear fission and fusion. They both are small atoms that release megawatts of energy that could destroy most of big cities. Now I wonder how is that possibile? Splitting an atom create MAJOR amounts of heat and energy combined what is the reason for that? The only thing that comes from my head is the force that is holding the protons and neutrons together is smashed with another atom. Im talking about heavy atoms not the simple ones because in every single second atom collided with each other. I'm confused on how a small small particle create a HUGE energy burst that puzzels me honestly. I feel sometimes they don't follow the laws of thermodynamics nor conservation of energy but I don't know what the input energy is in the first place to compare lol.
