Don: Fuel! They have fuel.
John: Hey, they got fuel!
Don: Yeah! Yeah. So if we'd just waited a couple hours, we wouldn't be here. Great.
Answer: Yes to all questions. The best theoretical estimate is that the universe is about 7 trillion light years across. That is about 250 times larger than the currently observable universe. So, yes, using trillions of light years as a unit of measure is appropriate. And, yes, the age of the universe is a measure of time, and the space between galaxies is a measure of distance.
