I remember in middle school I had a very passionate physics teacher who held extra astronomy classes for kids who wanted to join.
Particularly I remember when he presented the age of the universe.
The age was estimated with something like plus minus 10 billion years. The teacher made a big deal about how incredible this was. When I first heard that number it sounded beyond imprecise. But he explained: Now we actual had a ballpark figure. Before we didn’t know if it was thousands or quintillions of years, so plus minus 10 billions was really good and ground breaking.
With that in mind, this kinda seems like a minor adjustment.
I was in middle school in the mid-80s when I learned the Universe was something like 10-20 billion years old based on our estimates of the Hubble constant from the decade before. I was in high school in the late 80s and early 90s when we used the CBR measures to estimate 14 billion. I was in college when that was refined to 13.7 based on supernova data. That's been tweaked a bit here and there but mostly remained stable.
