Unfortunately, I have very little idea about gravitons, as these belong to the realm of theories not familiar to me. It would however, be nice to have them experimentally detected – we know quite surely that gravity does exist, yet we’re still missing a full quantum theory of it, unlike in the case of the other three fundamental forces – the electromagnetic, the weak and the strong.

Gravitons are a major theme of my study! I’m reading in your question “do you think there are quanta of gravity that propagate through the universe?” My answer is: yes, of course! We have many quantum theories that contain gravity (string theories are the usual example) but none of them are as well behaved as the Standard Model. The reason why is really technical. We know that whatever the theory that describes our universe it must, at low energy (that is in daily life or at the LHC, not in a black hole), contain something that that looks like gravity. Whether the full theory of our universe contains gravitons or not, they are a good description of our universe at the energy scales we usually see, our big question is how to make such theories behave better!
