time dilation in glass?

[cucumber]

probably a stupid question, but that's what I'm there for...

if light travels slower through glass than through air or vacuum, would time be going slower for me if i were sitting in a block of glass??


thanks.

No, it's the speed of light in a vacuum that matter's in relativity (infact you can completely forget about c being the speed of light in a vaccum as that is really just one of the physical values that it relates to) and not the speed of light through some medium.
