What is light? Victor M. Urbina is correct in my counting with his "black" and "white" particles.
Michelson demonstrated that the speed of light through air is slower than through the vacuum and that there is no aether. These and similar experiments with increasingly better interferometers killed two birds with one stone. It killed Newton’s corpuscle because particles were supposed to travel faster in opaque media. It also killed the wave because wave theory was predicated on the existence of the aether. Contemporary wave theorists vehemently protest this verdict because it summarily liquidates their beloved hypothesis. Relativists believe that they resolved the situation by renaming the aether and calling it
space-time. What the aether and space-time have in common is that they are both alleged to be physical mediums. Space-time must necessarily be a physical object in order for the mathematicians to conceive of photons and planets rolling on its curved surface.

I looked up the description of that one and it referenced the Live Science website. Here is the article about it, dated 24 February 2008:
Electron Filmed for First Time
Scientists have filmed an electron in motion for the first time, using a new technique that will allow researchers to study the tiny particle's movements directly.
Previously it was impossible to photograph electrons because of their extreme speediness, so scientists had to rely on more indirect methods. These methods could only measure the effect of an electron's movement, whereas the new technique can capture the entire event.
Extremely short flashes of light are necessary to capture an electron in motion. A technology developed within the last few years can generate short pulses of intense laser light, called attosecond pulses, to get the job done.
"It takes about 150 attoseconds for an electron to circle the nucleus of an atom. An attosecond is 10^-18 seconds long, or, expressed in another way: an attosecond is related to a second as a second is related to the age of the universe," said Johan Mauritsson of Lund University in Sweden.
Using another laser, scientists can guide the motion of the electron to capture a collision between an electron and an atom on film.
The length of the film Mauritsson and his colleagues made corresponds to a single oscillation of a wave of light . The speed of the event has been slowed down for human eyes. The results are detailed in the latest issue of the journal Physical Review Letters.
Mauritsson says the technique could also be used to study what happens in an atom when an electron leaves its shell.

When your understanding is flawed from square one, it inevitably leads to all sorts of extreme cases that require round about explanations.
Amen.

Also, to clarify, the entire EM spectrum is what we call “light” in this context, and it consists of:
- radio wave
- microwave
- infrared
- visible region
- ultraviolet
- x-ray
- gamma ray

Have you ever seen the theory about Perceptive Energy? (I'm not sure if that's the actual name of the Theory, but it fits the description )
Anywho; years ago it was proposed that light and sound both behaved in their respective ways because of the human perspection of how these things were "supposed" to act. That the world was literally different per species on the planet, and beings from other dimensions would have a completely different view on life and how they perceived light and sound. One of the experiments was; they aimed sound waves at a wall and then placed a sheet of glass between the wall and the sound source with holes in it. In a nutshell: While filming and viewing the experiment, the soundwaves did as expected and went through all the holes, bounced around, and some of them made it back through to the sound source. When the experiment wasn't being filmed or watched, the sound patterns and their returns behaved in a completely different way.
They made a kid-friendly documentary that touched on this years ago you might find interesting;
'What the Bleep do We know?' and its sequel:
'What the Bleep do We know? Further Down the Rabbit Hole.'
They are really weird docs, and seem like something you'd of watched in Middle School or just before getting in the Rail Cars at Jurassic Park, but at the same time, everything is broken down into layman's terms for the average guy/gal. They've got that woman in them.... I forget her name... the deaf woman that everybody hates. Anywho; an interesting watch.
"If a tree falls in the forest and there's no one there to hear it, does it make a sound? No. Because if there's no one there to see it....there is no tree."edit on 22-5-2011 by Mactire because: (no reason given)

- Permanently connects every atom in the Universe to all other atoms. The signal goes two ways simultaneously. The EM wave is one-way.
- Has an electric thread and a magnetic thread as opposed to a field.
- Has link length instead of wave length.
- Both have amplitude.
This and more is presented:
Ropes arriving from every atom in the Universe end at the electron shell. It is here that the threads comprising the rope fork out.
The proton: The electric thread continues straight to the center of the atom where all electric threads from the Universe converge. The proton has the shape of a sea urchin because it is a convergence of electric threads coming from every atom in the Universe. Thread density increases as we approach the center of the atom. This explains why at some small region near the atom, it becomes impenetrable.
The electron: The magnetic thread loops around and, together with the magnetic threads coming from every atom in the Universe, knits the wavy ball-of-yarn surface that De Broglie talked about.
The H-atom is a knot in the fabric of the matter floating in space. This model incorporates all the relevant features that the mechanics have identified. We have Rutherford’s impenetrable ‘proton’ at the very center (conver-gence of electric threads), DeBroglie’s integral wave, and Born’s cloud (or Lewis’s shell).

The politically correct view, nowadays, is that space-time has no substance, and e/m waves propagate with no medium.

I don't believe that statement accurately describes today's mainstream view. Space-time is widely considered to be a non-medium—a mathematical entity with no physical substance.
