While not being at complete rest with the surface, certainly, the air in the room you are sitting with is at rest. You don't think that is rediculous do you? I believe that the aether is composed of a "gas" like substance and it behaves the same as a gas in that it concentrates at the surface of highly gravitational objects and just like the Earth has an envelope of atmospheric gases that it drags through space, it may also drag a similar envelope of aether.

And this has a demonstrable effect called aberration. Where there is dragging of a medium, there is a boundary or transition to the region where it is not dragged. (If you like, imagine the layer of air being dragged with a golf ball, and the transition to air further out that is not dragged.) For waves that are borne by a medium, this introduces a bending at the boundary or transition layer. Then it is pretty easy to detect this bending, especially if the medium is being dragged around a rotating body that is also translating. All you need to do is to find a source that is beyond the transition, and then you watch for the *differential* effect of the bending as the receiver rotates. To see why there is a differential, just consider a point on the surface of the earth. The earth is in motion around the sun at about 60,000 mph. But the earth is also spining on its axis, so that the equator is moving west to east at 1,000 mph. This means that during the day, the surface of the earth is traveling at 59,000 mph with respect to the sun and at 61,000 mph at night. This difference would introduce a *shift* in the bending of a signal from a distant source that would be evident on a daily cycle. So a dragged aether model has in fact been looked at quiet thoroughly, and it is possible to calculate how much differential aberration you'd expect from the transition layer for light coming from a star. Then this was very carefully measured. To date, the absence of a differential aberration is the best counterevidence available regarding a dragged aether hypothesis. This was actually done quite a long time ago, if you will look it up on the web. PD

Here you made a mistake. You should wrote: "The Sun may also drag a similar envelope of aether. The drag is rotational." The rotating Sun drags the ether. So no relative velocity between planets and ether. The experiments show that rotating Earth do not drag ether. This is unexpected but it is a fact. S* ..

Then this was very carefully measured. To date, the absence of a differential aberration is the best counterevidence available regarding a dragged aether hypothesis. I have check it in the original Stokes paper and the letters Stokes-Kelvin. The Stokes theory of abberation is quite different then presented in the textbooks (and you). The Stokes ether is jelly like. It is rotating with the Sun but not rotating with the Earth. Stokes matematically proved that the abberation for such model is in agreement with the observations. So: "To date, the absence of a differential aberration is the best counterevidence available regarding a dragged aether hypothesis." apply to your hypothesis. Stokes Theory of abberation for ether dragged by the Sun rotation is fully proved. >This was actually done quite a long time ago, if you will look it up on the web. Your post is very important to the topic. It is opportunity to clarify the "dragged aether hypothesis." For Stokes-Kelvin the portion (Solar System) of ether is dragged by rotation of the Sun. The Earth drifts in this whirl. Who is the author of the hypothesis that the Earth cause the ether motion? S* |
