A Proposal: How To Scientifically Test the Precision and Accuracy of the Neolithic Winter Solstice Detector at Newgrange, Ireland

It is my belief that the passageway and specially designed baffled 'roof-box' at Newgrange Ireland could determine the specific day of the Winter Solstice in real time. And if this is true, it means that this Neolithic science was thousands of years ahead of its time and more advanced, in this regard, than Greek or Roman astronomy. Today we now have the tools to test this hypothesis scientifically. In this article, I spell out ways that it could be tested.
