Physics is the study of how things work in the world. In the future, scientists think they will learn even more about how things work by studying things that are very small and very big.
They will use special machines called particle accelerators to study tiny things called subatomic particles. These particles are too small to see with our eyes, so scientists use machines to make them go really fast and smash into each other. When they do this, they create even smaller particles that scientists can study to learn more about the world.
Scientists will also study things that are very big, like black holes. These are places in space where the gravity is so strong that even light can't escape. By studying black holes, scientists hope to learn more about how the universe works and how it was formed.
In the future, scientists may also discover new materials that can do things we can't even imagine right now. They may create things like transparent metals, which are tough like metal but see-through like glass. These materials could be used to make all sorts of new things, like super-strong buildings or cars that run on electricity.
Overall, the physics of the future is all about exploring the smallest and biggest parts of our world and discovering new things that can help us make the world a better place to live.
