Are there any current realistic best hopes to directly observe (or observe the absence of) a graviton? All I ever hear when I google around is that it needs a detector the size of Jupiter, so is there no inventive way to make this more practical? Do you see it happening in our lifetimes? Is it even possible (I've also heard neutrino shields in a such a detector would just collapse into a black hole)?

Why is it physically necessary that a detector has to be so large? Couldn't it be reduced down in scale through engineering in the same way computers have been?
