comment What does it mean to say “Gravity is the weakest of the forces”?
No, is not about the difference of coupling constants, is about quadratic divergence of Higgs mass correction (first order radiative correction). I will find a question about it. This area of comments is not appropriate for a more detailed answer.

Actually the Hierarchy problem is about the radiative corrections in the Higgs propagator. The large discrepancy of coupling constants is not a real problem.

comment How can I infer the topology of a quantum state (or band) from its Chern number?
Thank you for the answer. But, are there any relationship between Chern number and Genus (number of handles) or non-orientability? What's mean these numbers?

Not matter, the question could be undertood without any equation. Thank you for the help.
