Host Harsh Rain paints the Gupta Golden Age—vibrant markets, Ujjain’s observatories, Nalanda’s wisdom—where Aryabhata, a 23-year-old architect, crafts a 3D cosmic sphere. The Golapāda’s 50 verses define ecliptic and equator circles, place a spherical, spinning Earth within, grid the skies with coordinates, and compute eclipses with sines and shadows. Building on Episodes 20–24’s time, orbits, and math, Harsh ties Aryabhata’s model to NASA’s star charts, GPS, and eclipse apps, making the cosmos a calculable marvel. A starry-photo challenge, Sphere Quiz, and Earth-size teaser spark engagement, while Episode 26’s deeper dive beckons, inviting listeners to navigate Aryabhata’s heavens.Disclosures:General: Historical details (e.g., Pataliputra as Aryabhata’s base) rely on scholarly consensus but aren’t definitive. Gupta-era life is dramatized, grounded in context. The podcast is a creative exploration, unaffiliated with academic institutions or official records.
