Unlike me. I recognise a couple of words in this article (mostly prepositions and articles) but that's about it. However reading it was not a total waste of time for me, I now know what the coolest question in the world is. Here it is:
Can anyone seriously claim that the finiteness of the perturbative S-matrix elements of a badly divergent perturbation series settles the question of whether the soft graviton state produced in this process is a normalizable state in Fock space?
Um...I don't know, mate. Can anyone seriously claim it? That's a tough one (I guess). Thoughts guys?
