Who dares slap me with this when I haven't yet finished my first cup of coffee for the day? And then has the audacity to say "In actuality, we can see for 46 billion light years in all directions, for a total diameter of 92 billion light years." Doesn't that presuppose that We are at the center of the universe?

If our bodies' temp is 98.6°F, why isn't it the most comfortable temperature?

I think it is a confusing explantion. Why not simply say:
13.8 billion years old means the univers has existed that long.
A light year is a measure of distance using the speed of light - how long it takes to get from point a to point b at the speed of light.
When something is 46 billion light years away, that means it would take us 46 billion years to get there traveling at the speed of light . . . longer than the universe has existed!
What I find interesting about the article are the variables it tells us are used to calculate this: "The distance we can see in the Universe, from one distant end to the other, is 92 billion light years across."
