In 1887, Albert Michelson and Edward Morley performed an experiment in an attempt to detect variations in light traveling through the "ether," the name assigned to unseen particles that fill the vacuum of empty space. This experiment's negative results are held as critical evidence that the ether does not exist, supposedly conclusive proof.
However, there were unintentional assumptions being made: that the ether is stationary and that it travels specifically in the direction parallel with the ground.
In fact, there is an ether. These particles, however, are influenced by gravity. Around the earth, they are pulled by the force of gravity and physically travel in Figure-8 patterns through it. This produces the electromagnetic field of the Earth, as a result of gravity. See evidence at CascadingUniverse.Org
The reason their experiment did not show results of an ether influencing the light is because the experiment was done parallel to the ground. The ether, which makes up the electromagnetic field of the Earth, travels perpendicular to the ground. Due to the beams of light used in the experiment being parallel to the ground, both beams experienced the same influence of the ether.
There is an ether. The universe is infinite, divisible always into smaller and smaller particles. These particles all function the same but at different time dilation and, due to their relative mass compared to other particles, such as atoms or the Earth, they are observed differently. Sufficiently small particles are observed as light, these particles traveling together in a wave like atoms in the ocean.
Space is not empty but rather is filled with these ever smaller particles, like a jar filled with large rocks, and pebbles, and sand, and liquid so that all the volume is filled. These ever smaller particles are known as the ether. This ether, then, is manipulated by gravity so as to produce the universe as we see it.
