Would we be effected by the shock wave from Betelgeuse going supernova ?

[AFPhys]

Not at all. The “gas” shock wave will be impeded by many light years of impeding “material” (such as it is) and suffer from an inverse-squared decrease in energy as it comes toward us. The only real danger from a supernova this distant arises from the gamma rays IF AND ONLY IF they are focused in our general direction, which appears very unlikely in this case.
