And how large a bomb might it require now? Asking for a friend.
They conclude no size could do it now. I.e. could throw entire planet into Sun and it wouldn't be a self-sustaining fusion burn.
And probably goes without emphasis, but I will emp.: Q is whether fusion wd be *self-sustaining*. Earth + Sun = burns, but not sustaining.
I love the fact you thought you should qualify this 

Just don't want people thinking it would be totally fine to throw the Earth into Sun. Because it wouldn't be! #themoreyouknow
