EMR waves necessitate Ether???

How can light in its capacity to be wavelike, propagate through space without a medium of some sort? I mean, in a longitudinal wave, such as sound, the source will cause particles in the air to collide with one another, which will create a region of relative density, and this region of relative density happens to cause an interaction between air particles (essentially the medium) as the wave propagates through the air such that the next region is rareified, and then dense, rare, etc. And the means by which the information is transferred that enables this pattern of air through the path of propagation are the air particles, which are the medium by which the wave transfers. Now, I understand light is particulate as well, which means perhaps such waves contain their own particles, which cause self-propagation even in a vacuum, i dunno for sure. I want to know how this works and how information is transferred through electromagnetic radiation that causes a wave pattern?

The concept of an aether isn't new and has been in and out of scientific fashion repeatedly over the centuries. It has taken many vague forms, but you may be surprised that you are correct: there is actually a sort of aether that permeates all of Space.

The modern concept of an aether, though, is far more concrete than previous iterations, though when I name it, you may at first think otherwise.

The modern aether is called Probability.

Photons, electrons, and other sub-atomic particles exist only as peaks in a radiating probability wave. It's a topic that requires a basic understanding of modern physics and quantum mechanics to really begin to grasp.

For a better introduction than I can hope to provide without wasting an hour or two typing, see Brian Greene's book, "The Fabric of the Cosmos", which I really do suggest reading as a first step rather than, say, trying to Wikipedia the topic blindly (you'll only end up confusing yourself more, trust me).

Oh, and >>2 is an idiot.
