Three space-science puzzles get the expository treatment here, starting with the Moon's oddly lopsided shape. Scientists lay out competing explanations, from ancient magma oceans cooling unevenly to a slow collision with a second, smaller moon that may have merged into the near side we see today. The film then moves into the Sun's corona, tracing how solar superstorms could cripple power grids and satellites, and how small eruptions nicknamed 'campfires' on the solar surface are helping researchers predict them. The final segment tackles the Hubble tension, a persistent mismatch in measurements of the universe's expansion rate that leaves cosmologists arguing over a discrepancy of roughly a billion years in cosmic age estimates. Interviews with astronomers and physicists anchor each section, paired with CGI reconstructions of lunar formation, solar flares, and galaxy surveys. Rather than settling any of the three debates, the film lays out the rival theories and the evidence each side points to, leaving the reader to weigh which explanation holds up.
