Humans Accidentally Made a Space Cocoon For Ourselves Out of Radio Waves (vice.com)

An anonymous reader shares a Motherboard article: Humans have accidentally created a protective bubble around Earth by using very low frequency (VLF) radio transmissions to contact submarines in the ocean. It sounds nuts, but according to recent research published in Space Science Reviews, underwater communication through VLF channels has an outer space dimension. This video explainer, released by NASA on Wednesday, visualizes how radio waves wafting into space interact with the particles surrounding Earth, and influence their motion. Satellites in certain high-altitude orbits, such as NASA's particle-watching Van Allen Probes, have observed these VLF ripples creating an 'impenetrable boundary,' a phrase coined by study co-author Dan Baker, director of the University of Colorado's Laboratory for Atmospheric and Space Physics. This doesn't mean impenetrable to spacecraft or asteroids, per se, but rather to potentially harmful particle showers created by turbulent space weather.

      It wouldn't work on Mars because there are no oceans to put Submarines in to communicate with.

      1) Don't worry about the core, it'll last. It's currently at ~5000K and will be at ~4950K in a billion years... which is about 300M years after the surface will be baked sterile by the Sun.

      2) Even so... it would take a LONG time for the solar wind to strip our atmosphere away. And in fact, it turns out we were wrong about the effect of the Earth's magnetic field; it is actually helping the solar wind heat and strip the atmosphere. At current depletion rates, it's estimated to be good for another 4 billion years or so. That's more than 3 billion years after the planet is baked and around the time it'll be engulfed by the Sun.

      We really don't need to worry about the core, its magnetic field, or the density of the planetary atmosphere.

      Well since the frequency of your wife's birthday is around 1/31536000 Hz, you can always say you rounded that event to zero, which means that while you never tell her "happy birthday" it also means she never ages.

      Peeked at TFA, sounds like it amplifies an existing Van Allen belt. Probably doesn't work surgically. Probably impossible to set up a belt on other planets with known tech, but I don't know belts and maybe a mild one can be synthesized, then amplified. I imagine the scale/distribution of radio emitters required isn't too impossible since we did it accidentally.

    Maybe a first step in terraforming Mars. And does this "shield" keep particles in as well as out? If it works both ways it could help prevent atmospheric depletion and allow bulking up the atmosphere on celestial bodies that have lost their magnetic fields. Lake Armstrong here we come! And maybe even generation ships crossing interstellar distances.

    Would it work without the magnetic field of the earth? It appears to be interacting with Earth's magnetic field. Mars has a much weaker magnetic field, I don't know if the magnetic field is important for it to work, if it is, this wouldn't work on Mars.

    This effect has been known, and studied, for many years. One of the early discoverers, and researchers into the effect, was Robert Helliwell of Stanford. ELF generated by lightning, which is happening around the world all the time, was triggering this cleaning-out of the earth's inner radiation belt long before the first submarine ever existed. I'm afraid this is old news in a typical NASA PR flack package. I suspect there are people waiting in the wings ready to propose setting up large ELF transmitters along the equatorward edge of the auroral zone so as to clean out the radiation belts on a routine basis. I believe this sort of thing was even proposed (may still be on the books) as a way to dump out an artificial radiation belt generated by a high altitude nuclear explosion (like the Starfish experiment back in 1962) should some Bad Guys decide to do that as part of an attack on satellite assets.
