Hi. The VISIBLE universe is bounded by the distance light could have traveled since it started. If the universe is 13.5 billion years then anything farther than that is not visible. So 27 billion light years is as good a guess as any.

Puu, thats a difficulte question. The problem is that we know litle about the expantion rate of the univerce in the first moments after the big bang, and the calculation Age_of_the_universe*2*Speed_of_light can not be applied, because we are not sure if the speed of light at the beginning of the universe was the same it is now, or even if it is constant. So in the end, realy realy big is a good guess.

There is a theory which states that if ever anybody discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable. There is another theory which states that this has already happened.

The universe is constantly expanding so we dont really know. All we can do is measure the redshift of moving stars and a red shift means it is moving away from us.

It is not infintly big because it is still expanding. All I know is that it is really really big.
