Aether was widely believed to be the medium of light that fills the universe. However,the Michelson Morley experiment failed to detect the aether wind that should have been observed if the Earth was moving through the aether, so the existence of aether was not proven, and aether is now considered an obsolete physics theory. At that time, one of the hypotheses to explain the existence of aether even without the aether wind was the aether drag hypothesis, which proposed that the aether moves with the Earth. However, this hypothesis was rejected because it could not explain the aberration of light. Consequently, modern physics has progressed and developed on the premise that aether does not exist. Here I show that the aberration of light can be explained even if aether moves with the Earth. I clarified that the flowing aether does not receive light directly from above, but receives it from an upward diagonal forward angle according to the same principle as the aberration of light and transmits it linearly. This means that, for an observer on Earth moving at the same speed as the aether, the direction of light matches the direction observed in the aberration of light. This research finding strongly suggests the possibility of the existence of aether. Therefore, when I calculated the angle at which light from a star is bent by the gravity of the sun during a solar eclipse, assuming the existence of aether, it matched the value calculated by the theory of relativity. From now on I propose that various physical phenomena should be reconsidered assuming the existence of aether.This paper is a rewrite in English of a Japanese paper originally publishde in 2012, with new findings added.
