- lkbm 6y agoWhoa, that's crazy precise. They got it down to the tens of thousands? If so, seems like they should write "13.700 billion" for the first part. I'm a little suspicious of this number as-is. Looking for a source for those numbers, I found this[0]: > While previous estimates were 13.7 billion years old, give or take 130,000 years, new predictions hone in with more precision- at around 13.77 billion years, plus or minus 40 million years. Which is much less precise and feels a lot more believable.

- bhk 6y agoSo NASA said "plus or minus 130,000 years" when they were actually off by about 70 million years?
- johncolanduoni 6y agoThat’s a misprint, the WMAP measurement was plus or minus 130 million years.
