[00:00:00]Imagine everything around you is made of tiny, invisible building blocks called atoms. At the very center of every single atom is a super dense core called the nucleus. You can think of the nucleus like a tightly packed ball of protons and neutrons that are glued together by the strongest force in the entire universe. Nuclear physics is simply the study of this tiny core, figuring out how it manages to stay glued together and more importantly what happens when we mess with it. The real excitement begins when we realize how much power is trapped inside that tiny core. If scientists take a heavy nucleus like uranium and carefully split it enough, a massive amount of that glue energy is set free. This process is called nuclear fission. It is the exact same science that we use to heat water in nuclear power plants to generate [music] electricity. And it is also the sheer force behind nuclear weapons. It is like snapping a wildly stretched rubber band, but the energy released is unimaginably huge. On the flip side, instead of splitting atoms apart, we can also smash tiny ones together to make a bigger one. This is called nuclear fusion. It requires extreme [music] heat and pressure, but it releases even more energy than splitting them. Fusion is the ultimate engine of the universe. It is the exact process happening right now inside the sun and all the stars, keeping them burning bright for billions of years. So, when you look at nuclear physics, you are literally learning about the hidden, invisible power source that lights up our entire universe.
