This would not have been kind to any RF/EMF systems, be they GEO, LEO or terrestrial. We'd have been walking around marvelling at st elmo's fire coming off any point-contact junction between metal or exposed metal structure, with the most fantastic skies at night. On the other hand, would allergy sufferers be marvelling at the removal of all the dust and pollen? This would be like the outdoors becoming a giant anti-s…

Damn, you took me from “hope that doesn’t happen again in my lifetime” to “oh Jesus please let that happen tomorrow” in just a few words.

I spent my whole life only breathing through half a nostril on a good day. About 10 years ago I got surgery and Sublingual Immunotherapy drops, and the results have been life changing. I sleep better, my mind is clearer, I feel like an entirely new person. I am not exaggerating when I say that I still occasionally think about how nice it is to be able to breathe clearly.

I was recently on cortisone for 3 months due to another condition and whoa I didn't remember how cool life was without a perpetual running nose.

Oxygen is a hell of a drug. I use nose strips, and I'm addicted now too.

I tried nose strips but I don't like disposables. I now use silicone nostril openers - two little tubes attached at the base that you stick up your nose. It came as a set of 4 sizes so a bit of waste there, but one size fit me and one size fit my wife.

These work well, but I wonder about hygiene. I keep mine in a glass dish on my desktop and attempt to cleanse them in hydrogen peroxide on occasion.

Ultimately, surgery is the best option in my experienced opinion, but it also has diminishing returns over time (~20 years in my case). This occurred recently for me, and I am looking to consult with an ENT again, when I feel like taking the recovery leap. With that said, I am still functioning extremely better than I ever did when I couldn't breathe 20 years ago.

I would love to know where you got them from!

You can find them under the search phrase: "nasal dilator".

The panic about these is way out of proportion with the real risks. Modern systems have all sorts of over-voltage protection, and we no longer use "telegraph wires" directly connected to vulnerable electronics like speakers and amplifiers. All modern telecommunications are over fibre or radio links.

How much do wire distance, intended voltage matter? All the power electronics are almost certainly protected by caps, but are big office ethernet runs long enough to cause issues? What about coax cables? It seems like with how many more cables we have now, that one of them probably has a design that would cause notable inconvenience.

Over voltage protection is not provided by caps (generally), but MOV’s, Zenier Diodes, spark gaps, etc. [https://en.m.wikipedia.org/wiki/Surge_protector].

Essentially, components that kick in when a voltage exceeds a certain limit to allow that excess voltage to shunt to ground instead of continue to build up in the circuit.

Similar devices in pneumatics or hydraulics are pressure relief valves [https://en.m.wikipedia.org/wiki/Relief_valve], and they provide similar functionality - giving a easier/lower resistance path for the high voltage/pressure, so delicate things downstream don’t fail.

Geomagnetically induced currents generally become a problem over hundreds of kilometers. Long range electricity transmission lines are the main worry I believe and solar storm events have knocked off large grids occasionally.

I have no idea what the correlation is between particle flux (the metric reported here) and actual geomagnetic variation which induces the current (varying magnetic field causes voltage). Basically the charged particles zoom past earth, then loop back from the magnetotail towards the poles. The magnetohydrodynamics cause effects large enough to modulate the magnetic field on earths surface.

”We have this long conducting loop” is the issue. The Earth is one component of the loop.

The article casually mentions a "notorious" 775 AD event which I'd never heard about (insert relevant XKCD here), so here's Wikipedia: The event of 774 had no significant consequences for life on Earth, but had it happened in modern times, it might have produced catastrophic damage to modern technology, particularly to communication and space-borne navigation systems. https://en.wikipedia.org/wiki/774%E2%80%93775_car…

Not a single telegraph wire was operational, in the wake of the 775 AD event.

Good lord, you're right! Not even one functional iphone has been found from the period either!

If this is C14 then this requires biological matter. Carbon dating depends on C14 so I’d assume that this needs to be tied to a chain of tree ring dates going back to tie these events down. There’s no doubt evidence of stronger events further back, it would be interesting to see if theirs a loose record of suggested intensities for those. I take it most of these details will be in the happy which I’ll need to study.
