[jin54363]

if light travels so fast, how come it never caught a ninja?

If you think his accents annoying, its probably because you`re not used to the English language being spoken properly. It would be truer to say, that as an American, you`re the one with an accent.....

I would guess the "glass conflict" could be static electricity?.. But it's just a guess!

Very good learning experience. Great!

[laz2008]

yea, why does it slow down when going through glass/plastic?

[kalerite]

its just like if u drove a car through jelly, the fact that it is traveling through a denser object therefore increasing the amount of work the object must do

Why does light travel slower in glass / plastic?

@OrunitaVivi Sound speeds up in water, but light slows in water, even so light is still many many times faster than sound, although in a super cooled liquid they claim light slowed to 38 mph according to some article, didn't say what super cooled sound would do.
