The radius of the sun measures 432,000 miles. That same number appears in the Sumerian King List as the total years of antediluvian rule. It also marks the beginning of the Vedic time cycles, the Kali Yuga. The Dvapara Yuga doubles it to 864,000, which is the sun's full diameter. The Treta Yuga triples it to 1,296,000, and the Satya Yuga quadruples it to 1,728,000. Add them all together and you get the Mahayuga: 4,320,000 years. These numbers show up in the Bible, in Sumerian texts, in Vedic cosmology, and in the dimensions of the sun itself. The question isn't whether these correspondences exist. The question is why ancient cultures across vast distances encoded the same ratios into their sacred timekeeping systems, and whether those ratios reflect something real about cosmic cycles and planetary dynamics.
