HBS #6 Is Space Really Empty - There May Be More To It Than You Realize

Space is not empty. Space is a dynamic, structured environment filled with plasma, charged particles, magnetic fields, and the solar wind. In this space physics episode, we explore why “empty space” is a myth, how the solar wind flows through the heliosphere, how Earth’s magnetosphere traps energy in the Van Allen radiation belts, and how space weather, satellite drag, orbit decay, GPS disruption, and radiation exposure are direct consequences of living inside the Sun–Earth plasma system. This is astrophysics, plasma physics, and space science explained clearly—showing how the Sun’s magnetic fields and charged particles shape the space environment around Earth and influence our technology, our satellites, and our daily lives.
