I read in various places that a supernova can briefly outshine a galaxy, given the number of stars in our galaxy would it be fair to say that there have been a number of SN in our galaxy since mankind evolved ?
If so what would be the effect on our planet of a SN in the galaxy ? Would the radiation not adversely effect us ?
