“In a spiral galaxy, the ratio of dark-to-light matter is about a factor of ten. That’s probably a good number for the ratio of our ignorance-to-knowledge. We’re out of kindergarten, but only in about third grade.” – Vera Rubin 1928 – 2016

The night is clear, the stars a bright and this is just a sliver of the Milky Way but just in the top right of the frame there is another Galaxy, maybe 100 billion stars maybe more. but this humble photo is at best only 4% of what’s out there and here’s the good bit… It’s here too, this little pebble we call home is spinning through the universe at mindblowing speeds and every moment of every day the dark matter that Vera has predicted surrounds us. And here’s the really good bit, somebody alive today will observe it, measure it and prove its existence. That is a day I look forward to.

32 million miles away from yesterday Peeps!
