“Those differences could mean that current estimates of the age 
of the solar system overshoot that age by 1 million years or more. 
Historical estimates place the age at about 4.5 billion years—a 
number that is not precise enough to show a difference of one 
million—but more finely honed recent calculations place the 
age at more like 4.5672 billion years. One million years is still an 
eyeblink at this scale, representing the difference between 4.566 
and 4.567, but this difference is important in understanding the 
infant solar system.”
