Re: [Phys-L] more accurate parallax and an astronomy lesson

["Don" <dgpolvani@gmail.com>]

Very interesting!  It's nice to have lived long enough to see some of the most fundamental questions about the universe start to get answered so accurately (how it started, how it will end, how it came to be the way it is, etc.).  Much of this was essentially conjecture at the start of my career with little backup data.  Now we have such accurate/precise data!  Thanks BC for sharing.
