It would cost 0.6-2.6 trillion to repair electrical damages. 3.6%-15.5% of the anual GDP. The US military has a budget of 3.74% in 2022.

u/Arcosim 7d ago

Now add to that all the rioting, crime, anarchy and general societal collapse if a months-years long total blackout took place. Hard to repair something if the people and crews with the skills and know how are fighting for food or fending off rioting people desperate for food and water.

u/HeyGayHay 7d ago

Like with the Pandemic? Idiocy is the only driving factor for anarchic collapse of society.

People buying cars full of toilet paper because on facebook people read that the only worldwide toilet paper factor has no power anymore, while in reality they bought a cheap ass power plant to power their office pc and the thousands of other factories are working as always after 3 days. That's what would happen.

It's not like every single electrical device will be broken entirely. Some just need a fix. Some will work as always.

3

u/Arcosim 7d ago edited 7d ago

Comparing the 2020 pandemic to a total social collapse where all services, food production, supply chains (both external and internal), electric power, communications and hospitals stop working is ridiculous.

The problem isn't going to be people buying mass amounts of toilet paper and internet agitation, the problem in this scenario is going to be groups of people shooting at each other for food and water. Then add to that all the military conflicts that will break out worldwide and you have a global scale disaster.

Edit: and then you have the problem of restarting society, which is probably harder than fixing the broken stuff since all the services, companies and groups of people (national and international) are extremely interlinked. How do you, for example, restart a company that provides some key service/item without first finding all their critical employees, fix their lives and protect their families so they can go back to work and then simultaneously fix all their supply chains and third party services needs so they can restart production?

5

u/HeyGayHay 7d ago

That's ridiculous. Just because the walmart door is manually opened in the morning because the electrical wiring broke, doesn't mean people fight for water and shoot each other.

It's literally just a couple days with no power beside there where power engines are used. So all critical infrastructure is restored within a couple hours. Major suppliers receive first priority fixing while the electrical guys are still happy and well fed and they fix the supermarkets before people realize their phones are broke and gossip goes around that the world is ending. Miraculously, the supermarkets still are open and operating as always. But if no phone causes people to fight over bread and water, we were doomed already long ago. And a few months to restore normality even in the most outer places.

u/Arcosim 7d ago

That's ridiculous. Just because the walmart door is manually opened in the morning because the electrical wiring broke, doesn't mean people fight for water and shoot each other.

Yeah, except the problem here isn't Walmart's automatic doors not opening. It's Walmart's entire supply chain collapsing, Walmart's operating databases and internal network gone and their control/management systems inoperable. I don't think you understand the importance of supply chains and internal control/management systems. With these gone, or even relatively damaged, modern companies stop working.

u/HeyGayHay 7d ago

You are VASTLY overestimating the effects of a geomagnetic storm, even an utterly extreme one. I don't know if you read that one book where they visualize the fall of society due to a blackout, but a geomagnetic storm will not induce a total blackout.

Yes, there are options to cause such anarchy, like super-EMPs detonating in earths orbit targeting and disrupting satellites supplying a country. Would completly trash all major forms of communication, so people might go crazy.

Targeted hacker attack on a countries power grid, that causes the grid to malfunction and self-destroy. That would be an annihilation of society.

But a geomagnetic storm will "only" disrupt certain areas. Canada in example would be more fucked than the US overall. Florida might be hit severely, while California doesn't experience anything at all. NYC and Washington DC are at the highest risk. The major factor here is ground conductivity, which varies heavily even between cities. Coastlines are at higher risk too, due to water being a relatively good conductor.

Also, since Canada has a high risk overall, they have since 1989 spent more than 1.2 billion dollar into only protecting the Hydro-Quebec grid infrastructure against a geomagnetic storm. Countries all over the world with ah higher risk have already taken safety steps to prevent major damages.

So to sum it up, the supply chain will not be disrupted at all. Certain points along the supply chain might get disrupted, but one warehouse not operating and ten stores having no light/cooling will not cause the collapse of society. Atleast in the case of a geomagnetic storm.

u/Wraithbane01 8d ago

Forgive my ignorance. I thought the hazard was from induced current beyond threshold, regardless of whether or not the circuits are energized?

41

u/GoJebs 7d ago

Not from what I understand (an EE here).

The induced magnetic field would cause a surge that our architecture could handle. If it's energized then there would be a massive amount that would burn everything out.

Think of it in these simplified terms, a system designed for 15 amps can ground everything (without being connected to a breaker which is added protection) up to 15 amps safely. The bigger circuits that are rated for 100 amps can ground stuff up to 100 amps. So if a super wind hit us all the circuits in the world (if not energized) would be at their 100% grounding capacity for whatever is about to be induced. So the planet's grounding potential with all the circuits is quite massive and could (probably) take the hit.

Now phones and satellites and other isolated systems are another issue that I have no clue about but our power grid would most likely be fine.

EE here, but working with small and isolated systems instead of power lines. Electronics that aren't connected to the power grid would be so insignificantly affected it'd be unmeasurable. It's like lightning strike surges. They can induce massive energy in power lines, and fuck things up real good, but it's not like your phone is going to explode because lightning struck 50 meters away.

While there's an unfathomable amount of energy is a solar storm, it's still not a very dense energy field. Only massive electrically conductive structures are affected. And the global power grid is a pretty freaking huge structure.

A poor piece of electronics that's connected to said power grid though, is gonna be fucked beyond any chance of repair though lol

This was happened in 1989 in Quebec:

https://en.m.wikipedia.org/wiki/March_1989_geomagnetic_storm

Now imagine this happening globally. The issue isn't the resilience of isolated circuits. It's that the effects cascade up and down through things like supply chains, transportation, etc. If that happens for a prolonged time, an engineering crisis turns into a societal crisis.

https://en.m.wikipedia.org/wiki/Carrington_Event

2

u/GoJebs 7d ago

If you read the Wikipedia article you linked, you would find it is consistent with what I am saying though. It said it was on a rock barrier preventing proper grounding. I said with proper grounding and systems shut off (this doesn't appear to have been shut off) our systems would handle it just fine. You would also see that because of this event North America and other regions upgraded their systems in the same way Canada did to prevent outages specifically from these storms. All this information was under the Quebec Power Outage on that link.

This was in the 80's and most of the that system was built in the early 1900's-1940's when electricity was new. I assume they upgrade through the years but I assure you they didn't do all the upgrades to try and prevent this or keep it up to date with 80's technology. We have had many breakthroughs in power and current mitigation throughout these last 32 years as well as have this as an example of what can happen.

I can only speak to the US and Canada of the modern times but everything designed is over designed in terms of grounding/safety. 1989 might seem recent but in terms of technology advancement and the understanding of power safety and the building codes, that might as well been when humans discovered fire.

Magnetic field lines don't get destroyed like that. IDK what they are trying to convey with that in the video, but it's misleading. Cool visuals otherwise.

Edit: watched the source video, and the narrator explains that the magnetic fields get coupled and move around the Earth funneling gas towards the poles. So, I guess it's supposed to show that the fields get coupled. But instead it looks like the field gets dramatically weakened.

Magnetic field lines can break and combine like this. It’s only misleading in the sense that a limited number of magnetic field lines are shown, and because the charged particles are only shown when it connects to the Earth’s field.

u/quantizedself 7d ago

I know you are right, but the idea of them snapping doesn't really sit right with me because the field lines aren't really physical. I found this which is a nice, deeper explanation:

24

u/astrogringo 7d ago

Yes that stackexchange answer is quite good.

But one thing should be said explicitely: if you are studying plasma physics, you can build a mental model of the plasma as a fluid with rubber bands (the magnetic field lines) embedded into it, which move with the plasma.

This is a relatively simple model that allows you to get a rough intuitive understanding of how the plasma behaves. As surprising as that may sound, it can be justified by the equations of magnetohydrodynamics.

u/spork3 7d ago

It’s misleading a bit because the dayside field is replenished, so it doesn’t get diminished the way this video depicts, but otherwise the concepts are very informative. What’s happening is called magnetic reconnection. When field lines of opposite orientation are compressed together they can “reconnect”, which is the reconfiguration of the field lines that we’re seeing. When the field in the solar wind happens to be southward then we’ll have dayside reconnection, which transfers magnetic flux (field lines essentially) to the night side, where reconnection occurs again. Ions and electrons are injected into the auroral region and produce the beautiful light displays that we love. These processes typically last 10’s of minutes during quiet times and they are known as substorms. A proper geomagnetic storm occurs when you have a major solar event, like a corneal mass ejection, which can produce much more intense aurora.

11

u/base736 8d ago

Where in the video are they getting destroyed? The phenomenon depicted "behind" Earth is magnetic reconnection, which is responsible for the accelerating forces that give rise to the Aurora.

As a side note, my understanding is that the initial "upstream" interaction of the solar wind with the magnetic field, which is frequently given as the cause of the Aurora in Physics texts, is in fact far too low-energy. Instead, it gives rise to a related radio phenomenon (not finding the name of that right now).

17

u/quantizedself 8d ago

It looks like the magnetic field lines snap and disappear leaving the side facing the Earth more vulnerable, which is not really what happens asaik. It's true they reconnect on the far side, but the visualization is misleading imo

Maybe someone here can answer a question I have always had about this but never found an answer. If its all being directed towards the poles, are you less protected from the sun at the poles?

53

u/tobor_the_robot 8d ago

Not really - because the sun is at an oblique angle to the poles, much of the direct radiation energy (traveling in a straight line) is absorbed by layers of atmosphere. You are least protected from the sun at the equator, where the angle is more or less 90 degrees, meaning radiation is traveling through the least amount of atmosphere.

3

u/IshKebab 7d ago

You're conflating solar wind with sunlight. Totally different things. Solar wind is highly energetic charged particles. Sunlight is light, and is completely unaffected by Earth's magnetic field.

There definitely is more solar wind at the poles because that's what causes the northern lights but I don't really know how much of it reaches the surface and what effect it has on people.

"protected from the sun" is a vague statement, and it seems like it has been interpreted as regarding UV by some of the folks answrering.

Coming back to the topic of energetic charged particles, yes indeed, if you are near the magnetic poles you will get irradiated by more energetic charged particles.

If you go higher up in the atmosphere (for example at the cruising altitude of a modern jet) you will get irradiated by more energetic charged particles.

This effect is so slow that it hits our power grid like a DC current. I guess you could charge a battery with that energy but the cost would be astronomical and most of that equipment would go 20 years with hardly any utilization.

It's supposed to represent magnetic field lines (they don't get destroyed though; the video is horribly misleading). With magnetic field lines, the closer together they tend to be, the stronger the perceived force of another interacting magnetic object. Naturally, magnetic field lines tend to be very dense nearest to the magnet.

You can think of the earth as a giant magnet. What would happen if you held a compass needle at various points around the magnet? At a distance from the magnet, the needle would not appear to deviate. Right next to the magnet, the compass would deviate a lot. At a small distance, it would deviate a little. Same with the earth. The strength of the field increases the closer you get to the earth.

I love this video.

However, if you ask what those lines actually represent....... then my head starts hurtin

u/SheeEttin 8d ago

They just represent the orientation of the field. You know how on weather maps, pressure systems have circles around them? It's like that, kind of. The magnetic field of the Earth exerts a force on the solar wind. When it gets close enough, the particles either get repelled, causing them to miss earth and fly off into space, or if they get repelled toward the other pole, they get sucked down and become the aurora.

Well right but what is a magnetic field....

u/heathmon1856 7d ago

Magnetic field. The electrical force hits the earth which runs perpendicular to the electrical field. The magnetic field diverts a lot of nasty stuff from the earth.

wtf thats the wierdest graphic ive seen to show the magnetic field.

it doesnt erase the sun side and add to the far side of earth.

We're hanging in the void from a ball of nuclear fire a million times bigger than everything we've ever known, so large and so hot that it can sear our skin from nearly a hundred million miles away, and the radioactive flames of that fire are bearing down upon us and our world at all times.

Here's a better depiction of the Earth's magnetic bow shock wave from NASA, that someone else posted:

u/dpahoe 8d ago

Um.. am I the only one concerned about how the magnetic field is uneven after the wind passes? How does that affect Earth? Will it go back to normal? My OCD is kicking in..

u/truevelvet 8d ago

That's just a rather inaccurate representation. The core hasn't gone anywhere so there's no reason for the magnetic field to disappear or change

u/Mmh1105 8d ago

No, but it does distort. It would appear squashed on the side facing the sun, and elongated on the side facing away.

A bit like a boat going through water. If it were stationary, it would create a circular ripple. When moving, however, there is a bow wave and a wake.

This is just due to Newton's 3rd law (as the earth repels and diverts (ie changes the velocity; accelerates) the charged solar wind, so does the solar wind exert a force on the earth) and has been happening since the formation of the earth's outer core. Nothing to worry about.

This page has a good gif of it.

I’m aware of the carrington event, but that alone won’t cause much damage to humans. It’s only in the last 100 years that such an event could really do much to us from our reliance on tech. If something like that happened a 1000 years ago the only affect would be people being “where did those lights in the sky come from”

u/MyrddinHS 8d ago edited 7d ago

the field does move, like pushed closer to earth. it doesnt pop like a bubble, disappear and then get added to the far side.

u/McBonyknee 8d ago edited 8d ago

It's like the Gravitron ride at the carnival. If someone was to push you towards the center, sure you could move forward a bit, but as long it's spinning, you would be pushed back out.

You're the magnetic field and the Gravitron is the iron core dynamo of the earth.

It's elastic and bounces back.

u/theloosestofcannons 8d ago

it also makes our ionosphere reflective to radio waves, causing them to bounce off of it and head back toward earth at some angle of incidence.

u/brownbrady 8d ago

When the energy is released during these collisions, does that mean oxygen and nitrogen atoms get destroyed?

5

u/SheeEttin 8d ago

No, they're just gaining and losing electrons. It's the same principle that LEDs use. When you smack the oxygen('s component particles of protons and electrons) with energy in the form of electrons and protons, it gets excited. When it re-emits this energy, it comes out in the form of photons, which we see as the aurora.

u/calamarichris 7d ago

Dumb question, but aren't oxygen and nitrogen being consumed in the energy released in these collisions?

3

u/Dualio 7d ago

No the atoms are being bombarded with electrons but that only changes their energy state. When they regain their normal state they release the extra electron plus a photon.

Additional fun fact: Mars has a very irregular magnetic field, which means auroras (aurorae?) show up in discrete patches all over the planet! (source)

A poem I wrote because of this, I Think:

La luna Impaciente está presente, bajo este ardiente atardecer. Las translucidas nubes de inmóvil movimiento dibujan los colores del aura solar, sobre un fondo cielo azul. Para no caerse, el sol se aferra con uñas de alpinista a roca, que al precipicio, de esa cumbre, lentamente cae.

¿Qué se busca en ese vaivén?

¿Ser o no ser?

¿De qué sirve conocer a la silenciosa verdad?

Is it conceivable that a large enough flare could destroy the magnetic field around the earth?

I'm aware that the earth's core causes the the field, but would it be possible for a large enough flare to fuck with that somehow? or would it just recover afterwards
