The Nature of Light and Gravitational Field
Humans depend on the reflection of light in order to observe the world; anywhere from the remote cosmic starry sky to their own DNA structure. At present, only objects larger than photons can be observed (including using radars); this is the limit and bottleneck encountered today. It is a challenge to discover objects smaller than photons as well as to understand their forms and characteristics. The problem exists whether light is in a form of particles or waves. It is thought that in quantum physics light is in the form of particles, while in optics and cosmology light is thought to be in the form of electromagnetic waves. Both theories can satisfy specific arguments in physical practice. The “wave verses particle war” began in 1663, but the outcome of the argument that has lasted for centuries is a compromise that believes light has both the nature of wave and the nature of particle. It was pointed out by Bohr that the wave-particle duality depends on how we observe it. However, this compromise can only be reached within the characteristics of light and applied only in practice. Hence, what is the true nature of the “light” with such wave-particle duality? What is the most elementary composition of matter? We cannot always attribute unobservable matters as “dark matters”. Since it is impossible to observe matters smaller than “light” with our existing means of observation, can we not change our way of thinking and consider such smaller matters?
After the ether hypothesis was explored and developed by Hook, Huygens, Thomas Yang, Fresnel, Arago, Maxwell, Michelson, Faraday and Hertz, it is thought that light creates a transverse vibration in the medium (ether) as it generates the electromagnetic phenomenon, thus, the wave theory of light is an important cornerstone and pillar in optics and astronomy. However, based on the old ether theory, if we take ether as an absolutely static frame of reference there should be an ether wind of 30 km/s on the surface of the earth due to the rotation of the earth. However, the experimental results of Michelson and Morley revealed that light has nothing to do with reference. This experiment was a major turning point in the history of physics. Einstein also said, “As one cannot detect movement in the relativity to ether, the concept about the ether is excessive.” Although the ether hypothesis was required by the electromagnetic theories, supported by the double-slit interference experiment, the light aberration phenomenon and the Fizeau experiment, it was still completely abandoned.
