I don't see what's testable or falsifiable in here. Okay, it's good to get rid of epicycles, and intellectually pleasing, but it still looks like the same objections apply as have been raised around string theory. Even if this is the 'theory of everything', will we not end up with shorter equations that describe the same observations?

If they do find a way to predict space and gravity from quantum mechanics it probably will have testable predictions. They don't seem to have cracked it yet though. (Disclaimer - didn't read the paper.) I've long thought this would be a good way to go for research. I once had a crack at understanding Feynman's arguments that you could get general relativity from spin-2 particle theory in the book Lectures on Gravitation based on his 1965 lectures with the intention of writing a simplified version for Wikipedia. I failed - too hard - maybe someone else can do a laymans version? As far as I know there hasn't been very much progress since Feynman's attempts which were not renormalizable.
