Logically why would light move faster in vacuum than in a solid? *

light cannot travel in vacuum; it needs a medium to travel in just like mechanical waves
this is incorrect, light moves faster in a solid
in a solid light gets absorbed by atoms before coming out the other side
there's nothing for light to bounce off of in vacuum
