Gravity and the wave-particle duality of light are fundamentally different concepts and cannot be directly equated or compared.
Gravity is a fundamental force in nature that describes the attraction between objects with mass or energy. It is described by the theory of general relativity, which explains gravity as the curvature of spacetime caused by the presence of mass and energy. Gravity affects all objects and is not specific to light or electromagnetic waves.
On the other hand, the wave-particle duality of light is a characteristic of electromagnetic radiation, including light. It is a concept within the framework of quantum mechanics, which describes the behavior of particles and waves at the microscopic level. According to this duality, light can exhibit both particle-like behavior (as photons) and wave-like behavior (as electromagnetic waves).
The notion of an "aether" refers to a hypothetical medium that was once proposed as a medium for the propagation of electromagnetic waves, including light. However, experimental evidence, such as the Michelson-Morley experiment, showed that the classical idea of a luminiferous aether was not necessary to explain the behavior of light.
In modern physics, the wave-particle duality of light is understood within the framework of quantum field theory, where particles and fields are treated as fundamental entities. There is no need for an aether-like medium to explain the behavior of light or its wave-particle duality.
In summary, gravity and the wave-particle duality of light are distinct concepts that belong to different domains of physics. Gravity describes the force of attraction between objects with mass or energy, while the wave-particle duality of light pertains to the behavior of light as both a wave and a particle within the framework of quantum mechanics.
