The coolest question ever

My brother came to visit us here. He used my laptop and left the last thing he read open. This is the kind of stuff my brother reads and actually understands:

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?
