For the Dogons, Sirius is a three-star system. They accurately describe Sirius B: they say it is a companion star for Sirius that is invisible from Earth, that it has a 50-year orbital period, that it travels around Sirius along an elliptical path, and it is made of a heavy substance not found on Earth.
How did they even get the idea in the first place that elliptical orbits existed, rather than circular -much less apply this idea to some invisible star way out in space? And also to get it right by saying that Sirius A was at one of the foci, rather than just somewhere in the ellipse? And not at the centre? Wouldn’t the natural primitive idea seem to be, even if you wanted to say the orbit was elliptical, still to have Sirius itself at the centre? But no. They knew too much to make a mistake like that.
The Dogon describe Sirius B as ‘the infinitely tiny’. As we know, Sirius B is a white dwarf and the tiniest form of visible star in the universe. But what is really the most amazing of all the Dogon statements is this: ‘The star which is considered to be the smallest thing in the sky is also the heaviest: “Sirius B is the smallest thing there is.”
See diagrams above for the orbit of Sirius B around Sirius as portrayed by the Dogon in their sand drawings, which matches the ‘modern astronomy’ diagrams to an uncanny degree.
They also knew that Sirius B is composed of a special kind of material which is called sagala, from a root meaning ‘strong’, and that this material does not exist on the earth. They know that this material is heavier than all the iron on earth, all of which is perfectly true. For Sirius B is in reality made of super-dense matter of a kind which exists nowhere on earth.
So we see the Dogon presenting a theory of Sirius B which fits all known scientific facts, and even some which are not known it presents as well.”
The question is how do they know these things without the technology required? When asked, the Dogons say that beings from Sirius came to Earth and taught their ancestors.
