Considerations on Dark Matter and Ether

This paper discusses the similarity between dark matter, which fills up some of the total mass of the universe, and ether, which acts as a medium for light. It also presents a series of calculations and experimental methods to find ether. In modern physics, ether should not exist. Dark matter, a substance with mass, is essential to understand the structure of the universe or the rotation of galaxies. If ether is given mass, ether can be a suitable substance that can explain the characteristics of dark matter as it is. In this paper, we reexamine the deflection angle of starlight due to the change in direction of propagation by gravitational fields when ether is given mass, which was previously revealed. And we propose another experimental method to find ether (dark matter). The experiment compares the interference patterns that occur when two lights are incident on the same point on the surface of the Earth in a stationary atmosphere and when the wind blows perpendicular to the direction of propagation of the light. If ether, the medium of light, has mass, its properties are similar to those of dark matter, so we can propose that the dark matter we are looking for is ether.
