Just got through reading this article about findings that suggest the Hubble constant is about 15% smaller than previously believed. From the article: The new finding implies that the universe is. . . about 15.8 billion years old and about 180 billion light-years wide. My question is this: How does the universe get 180 billion light years wide in only 16 billion years without having matter travel faster than light? I'm sure there's a sensical explanation, I just have no idea what it is. P.S. Sorry if I'm posting in the wrong forum. Wasn't sure if I should post here or in the Other Sciences (i.e. astronomy) forum.
