It is talking about how big the now observable universe was at the beginning of the big bang. It’s not talking about the entire universe. The observable universe is a perfect but finite sphere. So think of a sphere with a 2 meter to 20 kilometer diameter at the beginning inflating to sphere that now has an 880 yottameter (10^24 meters) diameter.

Oh, it wasn’t a question, but an article. And by Ethan Spiegel nonetheless :). Thx for that, I love his content.
Yep, he is my favorite astronomy writer.
