'Dogon' brilliant

It is very disappointing to find, that for at least 70 years a substantial number of Astronomical scholars during that period time in our history, were aware that a North African tribe of people known as the Dogon, carried with them precise astronomical details, not only about the star system of Sirius, but also details of the Earths planetary system, and yet these scholars had made no attempt to publicly acknowledge this fact. These wonderful people had retained this accurate astronomical data For at least 3000 years, and yet none of these details were ever seriously debated by the astronomical societies. These Dogon people were aware of the elliptical orbits of our planets; the moons around Saturn etc, long before Kepler and every other famous scientist were born. For thousands of years the Dogon had named the Neutron star, that orbits the star Sirius, “Digitaria.” One would have thought during some part of our history, as a mark of respect, the astronomical hierarchy would have suggested that the name of this neutron star be changed from Sirius “B” To “Digitaria”. The fact that none of these emeritus scholars made any attempt to do this, speaks volumes about the flaws in their sense of justice. There is no excuse why this long over due name “change” can not now go ahead. I would be very interested to learn how many other people in this forum agree with this suggestion? WARO

The story is indeed fascinating. No doubt various ancient civilisations possessed incredibly "advanced" astronomical knowledge based on countless patient centuries of observation. I'd be interested to know what other people in this forum think of the following pages: www.philipcoppens.com/dogonshame.html www.ramtops.co.uk/dogon.html

If it's 7000 light years away wouldn't it be 7000 years old?

Actually, if it's 7000 light years away and was first observed 100 years ago wouldn't that make it 8000 years old?

Smithsonian Institution said:
The concept is similar to receiving pictures of a baby through the mail. We look at a picture taken at the hospital the first day and declare the baby in the picture as "newborn" regardless of how long it took the post office to deliver the picture. Assuming a fixed time for delivering the mail, a picture received a year later will show me a one-year-old (though, in fact, by the time we get the picture the child may be a week older than that). If we watch the child grow up entirely through pictures received in the mail, it doesn't really matter how long the mail delay is (as long as it is always the same); we can simply track the age by the day on which we receive the mail.
