why did so many stars in our galaxy go supernova in the past (some within just a few years of each other, and 2 - 3 each century on average), but we have observed none in the past 400 years?

>>	Anonymous Sun Jun 24 23:44:49 2018 No.9829529 Are you implying that's a statistically significant gap? 400 years is nothing.
