How does this relate to the rate at which an atomic clock ticks is determined by the aether pressure in which it exists? How does this relate to the pressure associated with the aether displaced by a massive object being gravity.

Guns and rulers. Just work out the trajectories (or guess as well as a ancient Roman soldier) enough to answer the two simple questions and you will see. Or you might earn a lifetime military service deferment acceptable to every army or shooting club on the planet. Sue...

Excluding air pressure, the trajectories will be the same.

You need a new avocation and for your own safety may I suggest one that doesn't involve anything heavy, fast or more than 20 cm off the ground. Sue...

Why don't you just explain what the point it is you are trying to make and how this has to do with the state of the aether as determined by its connections with the matter is the aether's state of displacement. What does the trajectory of the bullet have to do with gravity being the pressure associated with the aether displaced by the matter which is the Earth? |
