I fale at posting in appropriate thread. O well, turn this into a "speed record" theme. Lets see the fastest shit we've built!

Behold, this unassuming globule of glass is capable of accelerating particles to the speed of light.

Actually no--photons pop into existance at the speed of light.

You cannot accelerate something to the speed of light from any other speed or from any other speed to the speed of light.

You are right on the money with that first sentence. But the second only applies in a vacuum. Light speed varies with the material, so when you refract light through a material you slow it down.

How does refraction work on a microscopic scale? I was under the impression that the photons always went at light speed but when they are bounced around it takes time.

Like someone who is driving at a constant 100 km/hr but taking longer than 1 hour to reach a destination 100 km away because of an indirect route.

speed of light is different in different materials. Light going through water moves at different speed then light going through air, etc, etc. difference causes refraction when observed by human eye.

side note: Some physiscists have made crazy-ass contraptions that have slowed light down to less than 1mph. Also, for a while now we have had high speed cameras that are fast enough to stop-motion light. I wish I could find an example picture because they're bad ass.
