No, space is not merely the absence of matter. In physics, space is considered as a fundamental entity in which matter and energy exist and interact. It is a three-dimensional extent in which physical phenomena occur.
Space can be described as a mathematical framework that provides the coordinates and dimensions necessary to locate objects and events. It is a concept that encompasses the dimensions of length, width, and height, allowing for the measurement and description of distances and positions.
While space can be devoid of matter in certain regions, such as the vast expanses between celestial objects in the universe, it is still an active medium where various physical processes and interactions occur. Space itself can have properties and can be influenced by gravity, electromagnetic fields, and other forces.
Moreover, according to modern physics, space is not considered to be empty but is filled with fields, including electromagnetic fields and quantum fields, which can fluctuate and give rise to particle interactions.
Therefore, space is more than just the absence of matter. It is a dynamic framework that encompasses the existence of matter, energy, and their interactions.
