1. Get involved in an internet argument about the Nazis.
2. Insist, against all comers, that Hitler is 'like Hitler', and that all the historical parallels and precedents back up your argument that the Nazis bear important similarities to the Nazis. Call anyone who disagrees with you racists.
3. The universe will rapidly converge in a naked singularity centred upon Rachel Maddow, and will explode. Easy!
So kids, now that you know how to make the universe explode in your own home - don't try this at home.
