The Hollow Moon: Earth's Artificial Satellite

Apollo seismic data indicated unexpected lunar interior properties during impact experiments from 1969-1977. Prolonged vibrations following controlled crashes were attributed to dry, fractured rock layers amplifying seismic waves. The Moon's lower density compared to Earth reflects different composition and formation processes. Orbital mechanics and tidal locking represent natural phenomena observed throughout the solar system. Current scientific consensus maintains the Moon formed through a giant impact hypothesis approximately 4.5 billion years ago, with all anomalies explainable through conventional geological and astronomical processes.

While Apollo seismic data did reveal unusual properties, mainstream science provides conventional explanations for observed anomalies. The "ringing" effect likely results from the Moon's dry, fractured interior amplifying vibrations rather than indicating hollowness. However, significant gaps remain in our understanding of lunar formation and interior structure. The statistical improbability of certain orbital characteristics continues to intrigue researchers. Until more comprehensive lunar exploration occurs, including deep core sampling and advanced seismic mapping, the hollow Moon theory remains an intriguing possibility that challenges our assumptions about natural satellite formation and the history of our solar system.
