This may not be applicable in this instance (I haven't read your conversation from beginning), but does anyone know anything about trapping light in a material? Is the trapped light still moving, as in bouncing around? Or is it truly stopped?

The light isn't really "stopped" what happens is that the atoms absorb the photons (at which point the photon ceases to exist as such) and then when the atoms are triggered, they emit identical photons to the ones they absorbed.
Ceases to exist as such? What actually happens to the photons? What form do they take whilst stored?

A higher energy state for the atom.

Welcome back.
Do you plan to respond to post #332?
If not, please retract your claim that you can see light the instant it is emitted from an object (i.e. your claim that the speed of light is infinite).
If there is no response or retraction from you within a reasonable time, I'll probably have to ban you again.

Let me ask you who has this in their signature:
"It is the mark of an educated mind to be able to entertain a thought without accepting it." - Aristotle.
Ask me specifically what you want me to answer.
I aint joining any groups man. Because they can all go fuck themselves.
What do you want me to answer?
I just said everything we see is real time. Who is in the supernatural here me or you?
So...prove it. should be easy.
Yep. And that's incorrect.
So according to you everything is dependent on light. Why dont we just erase light and say everything is dependent on speed?
John99:
I want you to answer the following questions, from post #332 - like I said:
1. Suppose I am 300 metres away from you. You watch me clap my hands (from where you are). Do you think you will hear the sound of the clap instantaneously (i.e. at approximately the same time you see the clap)? Or will there be a delay before you hear the clap? (Bear in mind that the speed of sound in air is about 300 metres per second.)
2. Going back to light, then, and given that the speed of light is about 300,000,000 metres per second, do you think that there might also be a delay between the time I clap my hands and the time you see the clap?
3. The measured speed of light is 300,000,000 metres per second. How long does it take light to travel 1 metre, John99?
That will do for a start.

James,
Can you prove that light travels 300,000,000 metres per second?
You know what?
Forget all the BS. You prove it to me right now.
Under every circumstance i want you to qualify what you just said.
Now yu are mixing up light and sound. OK...Does light have an echo? When we hear an echo is it 2, 3, 4, 5,..... instances or just the same sound. The two are not comparable james so forget that.

What do you think a reflection is?

And you're wrong.
You haven't been able to provide a single shred of support for this claim.
You. As usual.
Prove YOUR claim.
You can say whatever you like. Won't change the underlying physics.

From your link:
I've preached this many times. To take it a step further, in order for the speed of light to be constant in a vacuum, and light travel time to define the meter, the "second" must be an absolute!
Distance and time are locked hand in hand, not to be contracted or dilated, respectively.
BY DEFINITION, 1/299,792,458 of a second of light travel time IS 1 meter!
