# Variation of fine structure constant and spacetime?

Hi all,

I'm going to ask a naive question - hope that's ok. There's been a lot of recent discussion of the results from Webb et al. which indicate that the fine structure constant varies spatially. I realize the results are very controversial - I'm wondering, hypothetically, if these results were shown to be correct:

Would this have implications for our view of spacetime? I.e. would the 'structure' of spacetime vary with location? E.g., would we still work with a smooth 3+1 manifold? Would the geometry of the manifold change?

Sorry, I realize that the above is probably not very coherent - it's a question from a novice ;-)

Thanks.

J.
