If something hat has no volume and no mass can exist ,what does it mean to say that something physical exists?
In physics, "exist" refers to the presence or occurrence of something in the physical world or universe. It can also refer to the fundamental building blocks of the universe, such as particles and fields.
According to the principle of quantum mechanics, something can exist in a state of superposition, where it exists in multiple states at the same time. However, it is not observable until a measurement is made, collapsing the superposition into a single state.
The laws of physics govern the behavior and interactions of all existing entities in the universe. The concept of existence is essential in understanding and applying these laws to the physical world.
While the concept of existence is fundamental to both physics and philosophy, there are differences in how it is defined and understood. In philosophy, existence can refer to the abstract and metaphysical, while in physics, it is primarily concerned with the physical and observable world.
In physics, the existence of something is typically proven through empirical evidence, such as observations and experiments. However, there are also theoretical considerations, such as mathematical models and logical deductions, that can support the existence of a concept or entity.
