NASA spends a great deal of time researching the earth as well as its surrounding area environment. One specific function of rate of interest are the Van Allen belts, so much to ensure that NASA developed special probes to research study them! They’ve now found a protective bubble they believe has been produced by human transmissions in the VLF range.
VLF transmissions cover the 3-30 kHz range, as well as therefore bandwidth is extremely limited. VLF hardware is mainly utilized to interact with submarines, often to remind them that, yes, whatever is still fine and there’s no requirement to launch the nukes yet. It’s likewise utilized for navigation as well as broadcasting time signals.
It seems that this human transmission has produced a barrier of sorts in the environment that protects it against radiation from space. Interestingly, the outside edge of this “VLF Bubble” seems to correspond extremely carefully with the innermost edge of the Van Allen belts triggered by Earth’s magnetic field. What’s more, the inner limit of the Van Allan belts now appears to be much farther away from the Earth’s surface than it was in the 1960s, which suggests that man-made VLF transmissions might be accountable for pushing the limit outwards.
Overall, this seems like an accidental, however potentially positive impact of human activity – the barrier protects the earth from potentially harmful radiation. NASA’s YouTube video on the topic suggests that comprehending this system much better might allow us to safeguard our satellites as well as area cars from a few of the harmful impacts of the area environment.
NASA does a great deal of high-end research study – like the EM drive that’s got a great deal of people extremely confused best now.
