Can we make the Sun explode?

The Sun cannot explode. University of Michigan astronomer Subrahmanyan Chandrasekhar proved this sixty years ago, for which he won a Nobel Prize. The minimum mass for a star to explode is 4.2 times the Sun's mass. And all the nukes the human race has ever built or ever will build are so puny compared to the Sun that even if approaching the Sun didn't make them evaporate in the heat, they still would have no noticeable effect.
