In applied mathematics, classical physics, and quantum mechanics, the domains of space and time are indeed considered fundamental aspects of the physical universe. Although they are represented mathematically, their existence and role in shaping physical phenomena is well established and supported by experimental evidence and experimental observations.
In terms of applied mathematics, space and time are indeed abstract and conceptual constructs or imaginary. They are represented mathematically using coordinates and metrics to describe the location and relationship between objects and events.
Between classical physics and quantum mechanics, space and time are considered fundamental aspects of our physical universe. They provide the framework in which all physical events occur and are essential for describing the behavior of matter and energy.
While space and time do not interact in the same way as particles or energy do, they are interconnected in classical physics and quantum mechanics. The behavior of particles and matter described by classical mechanics, quantum mechanics depend on the geometry of space and time.
Space and time play an important role in shaping the behavior of the universe in both classical physics and quantum mechanics. They are used to formulate equations of motion, determine energy and momentum, and understand the evolution of physical systems over time.
In classical physics and in many aspects of quantum mechanics, space and time are treated as invariant. This means that the laws of physics remain consistent regardless of the observer's position or orientation.
