The podcast episodes explore how scientists use various techniques, including seismology, gravity mapping, and magnetic field analysis, to probe the interiors of planets and uncover their complex structures.

The generation, characteristics, and historical records encoded in planetary magnetic fields are valuable sources of information about interior dynamics and evolution, as demonstrated in Episode 264 | Sabine Stanley on What's Inside Planets.

Magnetic fields and gravitational anomalies also play a central role in the discussion of portals and wormholes, as presented in UFOs and Wormholes - The Evidence with Billy Carson and Caroline Cory.
