Light Years Ago by Tim O'Brien Light Years Ago by Tim O'Brien shows that the symbols of the sun engraved on the backstone of Cairn T at Loughcrew are precisely positioned to measure solar movement. A beam of light from the rising sun around the time of the March and September equinoxes is mapped on the backstone.
