Scalar field theory

Scalar field theory is a way of explaining the physical world by thinking of it as made up of lots of different fields, like a grid. Each point on the grid has a number at it, called a scalar, which can change depending on what's happening in that part of the world at the time. By understanding how these scalars interact with each other, scientists can come up with ways to describe how particles and forces interact with each other, which can help them better understand the physical universe.
