Comments on: Eta Car: tick tock, tick tock http://blogs.discovermagazine.com/badastronomy/2007/06/20/eta-car-tick-tock-tick-tock/ I am an astronomer, writer, and skeptic. I likes reality the way it is, and I aims to keep it that way. My real name is Phil Plait, and I run the Bad Astronomy blog.

And also, the nuke would have to be about the size of our earth to destroy a sypermassive star. it will be inpossible to send a nuke to a star so far away. the reason for this is because the original plan for defence of the earth from asteroids is to nuke the incimng asteroid but the main reason why this wouldn’t work even if it was a little as 100,000miles incoming the nuke wouldn’t have enough fuel to get to the star.
