Ancient time-& space; periodisation; Sanatan vigyan via indo archaeology

Background: सनातन विज्ञान Sanatan vigyaan (perennial sciences) alias वेदिक विज्ञान edic vigyan (Indian plural sciences) has an enviable tome of tradition & literature about ब्रह्माण्ड (Brahmanda cosmos); space-&-time. ProblemObjective: However, no archeological member nor any workable device has thus far been reported; scientific validation included. Result: We herein report one such item known as the षहस्रलिङ्गम् Sahasralingam (millennia indicator) and also describe and discuss ‘how to use’ and ‘how to infer’ ~ hand-on.Main Points: Time being the enquiry sun’s light-shade is used as reference. The Sahasralingam monolithic devices is wrapped with an etched abacuses. We use it for study. Posits as versatile to ascertain earth-sun space architecture; evidenced earth orbit’s sun in खगोल khagola (infracted circle) at a curvature of 70 (degrees). Light in space is in relation to shadow on earth; shadow shifts as motion in space; it’s angle as motion’s plain; it speaks the time in space. Such end products computed and hypothesis is formulated as सिद्धान्त युगब्द siddhanta yugabda (optimized space-time period theories). Such periodisation not provable beyond bronze age कलि युग kali yuga (quarrelsome period). Such periodisation, optimisation, numerical & geometrical methods, etc., was unlimited brain storming game using mathematics to compass space and calculate {inter space} time related academic gymnastics. History of Science. Applications are pure mathematics (no religion, no statepolitics only dispassionate, brilliant computational academics). 1st time, ground breaking on pan global basis.
