But like I said, that is how I feel and I'm sure not everyone agrees with that. Which is fine.

Rag: I agree that the activities you list aren't good. However, I belive that there are angels and demons, and yes, the devil. Although we can't see these spiritual beings, they are around us and influence us for good and evil. I also believe that some evil people are aided by demons, just as believers can be aided by God's angels. A person must be very careful to not get caught up in the spiritual realm, as it is easy to be deceived....Greybeard

I don't want to sound crass, but I would be very interested in seeing some evidence to support this postulation. I consider myself well-read and have never encountered any reading to support your position.

EDIT: Yeah, that 'changing medium' thing - its called the 'refractive index'....

It was in my physics book Last year, which is generally accepted as the best physics text book out there. Unfortunately, I only have volume one of that book now, so I can't look it up to relate it to you.

It is all about reference frames. From our reference frame, the light appears to slow down when going into a thicker medium. But from the reference frame of the light, it has not decreased in speed at all. That is what matters more. Our perception is inherently flawed anyways.

I welcome you to join us in the 21st century if you would like to. Its up to you, really.

I don't know exactly about the SoL thing but there are many pages out there. Try this one:

Same thing.
The initial wavefront moving thorugh the material goes right through at the speed of light.
The interference from the secondary EM waves generated by the atoms jostled by the main wave adds up to produce a new wave whos peaks and valleys change position slower than you'd expect.

Look at standing waves on a rope as a slowed down example. You start waving the rope (attached to a wall or a friend on the other side)
You see a succession of waves travel down the rope, hit the wall, and then reflect back, and start to interfere with the later waves you made.
When the two waves interfere in the rope, the total result is a wave that looks like it isn't moving at all.
The energy is still moving along at the normal speed, but the interference causes the illusion of slower (or faster (!)) velocities.
Given appropriate conditions, you can actually make the wave peaks appear to "travel" faster than C, but the far side of the apparatus will not light up until enough time has passed for a beam at speed C to travel the length of the apparatus.

Why the heck does Atrocities keep creating threads that spiral out of control?

The Christian God (and all other religions) is a creation of mankind to explain things that we can not explain otherwise.

So you're saying there is no God? That mankind made Him up? All you have to do is look around, look at the evidence, look through his Word (the Bible), and it is plain as day that there is a God.
