No, it doesn't. The article says the 'observable universe' is about 46 billion light years in radius. (that's 96 billion light years 'across' ).
It also says:
So how big is our universe? Well we don't really know,...
It is actually possible that the universe is less than 46 billion light years in radius as that estimate for the observable universe is based on the assumption that it is actually bigger than that.
What I find interesting is you have been making the claim or similar for years in this forum and I correct you every time, but you just keep trotting it out. One would have thought you would have at least looked it up and tried to confirm it before making the claim again.
I hope that now you finally know that the size of the universe is totally unknown (as confirmed by your own reference) and there is no evidence whatsoever that it is finite or approximately what size it is. The best we can do is approximate a lower bound for the size (which is less than 46 billion light years radius, but I would have to look up the latest research to get a more accurate lower bound).
Please don't spread misinformation about it again. If you believe I am mistaken please feel free to find references that contradict me as I am more than willing to learn more about it if such evidence does exist.
