Probably the dot over the letter 'i' .....

Nobody knows - we can guestimate but because we don't know the shape of the universe it's impossible to say.

depends do you want that loopy or stringy?

either way the Plank length is 10^-33 centimeters which is the smallest thing that makes sense

I think it is expected the graviton will be about this size if it exists

Well, it's smaller than the Planck length (by one letter).

Don't think that is quite how space works. In much the same way as one doesn't ask "is the age of the universe the period since the big bang, or do we count the time before the big bag too?"

Correct, there is no void to expand into as a void implies the universe is expanding into something.... which I pretty sure the accepted wisdom is that it isn't. If that makes any sense at all, which it doesn't!

Surely it would be more accurate to use the distance of the furthest known object as the radius. Im not saying we are the centre of the universe, but it seems more logical than using is as diameter.
