Abstract

This article suggests a type of ether called 'generated' that is translated by the Earth, but not rotated, which explains why GPS needs compensation for Sagnac effect. This ether defines light velocity and provides reference for that velocity, but this ether cannot change orientation of the wavefront's plane, which explains why this ether has the same starlight aberration as an absolute ether, and therefore cannot be ruled out by starlight aberration. Michelson-Morley's failure is explained, and also why only first order effects of light's velocity, not direction, can provide manifestations concerning the ether-wind problem.
