OK so the Big Bang maybe happened when two M-Branes banged into one another: and there’s another brane-bang on the way some time soon maybe. And at CERN currently they’re building a particle-accelerator big enough that it will prove the existence of Sparticles – haha SPARTICLES!! – by banging stuff into other stuff. Well what if this bang IS the other bang?

(OK I have always been absurdly worried abt this: when I was 13 I wrote a story where scientists created a trans-uranic element so massive that it WAS the universe.)
