An invisible, weak energy field wrapped around our planet Earth has finally been detected and measured.
It’s called the ambipolar field, an electric field first hypothesized more than 60 years ago, and its discovery will change the way we study and understand the behavior and evolution of our beautiful, ever-changing world.
“Any planet with an atmosphere should have an ambipolar field,” says astronomer Glyn Collinson of NASA’s Goddard Space Flight Center.
“Now that we’ve finally measured it, we can begin learning how it’s shaped our planet as well as others over time.”
Earth isn’t just a blob of dirt sitting inert in space. It’s surrounded by all sorts of fields. There’s the gravity field. We don’t know a lot about gravity, especially considering how ubiquitous it is, but without gravity we wouldn’t have a planet. Gravity also helps keep the atmosphere snug against the surface.
There’s also the magnetic field, which is generated by the rotating, conducting material in Earth’s interior, converting kinetic energy into the magnetic field that spins out into space. This protects our planet from the effects of the solar wind and radiation, and also helps to keep the atmosphere from blowing away.
