How does light manage to travel through glass and emerge at nearly the exact same spot on the other side? I know that most glass is afflicted by various deformations in its structure, but some high grade glass, such as that which composes my computer desk does not possess any notable light distorting attributes. It seems as if light moves through too many atoms to not be effected....do the atoms essentially ignore the photons? You could say that they only pass through the vast distance between the electron orbits and the nucleus...but then that would apply to all matter; unless...there is some type of field that normally catches the photons while going through the empty space that is not present in glass. Perhaps the chemistry of the components conveying the glass form a type of comb filtering of their fields, rendering the space in between unaffected.
