Stars attract hydrogen; planets repel it — suggesting that gravity exhibits polarity. Under the DPG (Dual Polarity Gravity) framework, positive gravity drives hydrogen inflow in fusion-active stars, while negative gravity drives hydrogen escape from iron-core planets. This gravitational polarity is proposed as the driving force behind the cosmic circulation of hydrogen and helium, supported by five independent observational anchors.
