the velocity of light is constant not in whole universe it depends from medium to medium there may be a constant speed of light in one medium but it may be some other in other medium.
Many scientist have tried to explain this phenomena Eienstein has said that when light travels in the form of packets i.e. photons . when this light enters from one medium to another then these photons strike the molecules present in medium and thus their speed slows down just like hurdles kept in ones way.
the velocity of light in a medium is constant everywhere. what confused you must have been an ambiguous statement that didnt say anything about the medium. for eg. the velocity of light in vacuum is constant everywhere in the universe i.e. approximated to 3 * 10^8 m.s^-1
velocity of light in medium is related to refractive index of that medium as
c/v =u (refractive index)
c is speed of light vaccume
so, v is inversly proportional to refractive index
therefore on passing through dencer media speed gets reduced...
