* Quantum theory deals with probabilities, not shapes. It describes the likelihood of finding a particle in a certain location, not its exact shape.
* Particles don't have a fixed shape. In quantum mechanics, particles are often described as wave functions, which are mathematical representations of their probability distributions. The concept of a "shape" in the classical sense doesn't necessarily apply.
* Some particles are fundamentally point-like. For example, electrons are considered point-like particles, meaning they have no internal structure and no defined shape.
* The shape of an object depends on its energy state. Even for larger objects, the shape is influenced by quantum effects, but these are usually negligible at the macroscopic level. For example, the shape of a molecule is determined by the arrangement of its atoms, which are influenced by quantum interactions.
Think of it this way: Quantum theory doesn't specify a shape for objects. It focuses on their behavior and properties. A "round" object is just one possible shape, and its existence depends on the specific context and energy state of the object.
