EMPs aren’t science fiction. Real militaries are experimenting on real EMP generators, and as Starfish Prime showed us, space nukes can send powerful EMPs to the surface. So what exactly is an EMP, and how dangerous are they?

Actually, there are two such scientifically educated state leaders, one being ex President Jimmy Carter and the other ex chancellor Angela Merkel. And both had to deal with nuclear breakdowns, one even in his own country (Three Mile Island). Angela Merkel was actually in favour of nuclear energy; but seeing the consequences of the Fukushima incident and the following rejection of nuclear plants by the population, she initiated the shutdown of the (already quite old) german power plants. But this won't help against the hubris of other state leaders. The problem is, you cannot put a whole country beneath a Faraday cage (I assume that this would ameliorate the effect on the objects inside, otoh the grid itself might be hit with energy of such an intensity that it begins to melt... but I am just a layperson, so please correct me if I am in the wrong)

I was taught in Chemical Officer Basic Course that EMP was like "free electricity" in the air that could be picked up by antennas and long lengths of wire. Digging a little deeper I got into the physics of different EMP spikes caused by different mechanisms. After wading through some complex equations, I could see why they dumbed it down for Second Lieutenants.

On kind of a tangent, this is part of the reason why vacuum tubes were used in various militaries for radar and radio communications all the way up into the early 90's even though they are power hungry and sensitive to RF interference. A vacuum tube regularly operates the plates at 100-300 volts, and if you do somehow manage to over-volt the tube with a transient pulse, you will likely just get an arc inside the tube which will burn a small spot on the plates which gives the tube a good chance of still being somewhat operational in the short term. Transistorized circuits operate at relatively much lower voltages, and a large over-voltage event has a much higher probability of destroying some or all of the circuitry, leaving the equipment of the time useless until replaced. Modern technology can be hardened against these events to a much greater degree, but back then it just made more sense to stick with huge stockpiles of tubes. The upside of this is now I can listen to these programs on a vacuum tube headphone amplifier that uses readily available military surplus tubes. Currently I have a computer with a motherboard made in Taiwan feeding a DAC and amplifier made in the US using a Russian 6Н23П tube driving a set of headphones made in China. If only these actual countries could get along this well :(

I remember that March 1989 CME well. Was just going to work for 6am early morning shift. It was still dark at that time of the year in the UK and the sky was flashing all over the place. People brushed it off as lightning, but I pointed out it was clear and there was no storm around. Knew what it was straight away and needless to say some of the guys were pretty freaked out that the sun could do that. Awesome display of power!
@markgallagher5908 2 ай бұрын
I saw a similar event once, there was bright white flashes in the sky but there was no sound of thunder, this continued for a couple of hours, I couldn't understand what i was seeing. At the time I assumed there was a line of thunderstorms in the distance that stayed off the coast and ran parallel to it. The event went on so long that made it unlikely that it was from far off lightning strikes and we don't get many thunderstorms in Ireland. This wasn't in in '89 so it wasn't the same event you saw.

First basic issue with orbital usage is filling it up to the point where you can’t pass through it. Second issue is having the satellites turn to junk and then crashing into useful satellites, which then makes them useless junk. Third issue is having an EMP turning satellites into junk. Basically we need to keep the orbit clear enough so that it doesn’t get filled with junk otherwise we can’t use it. Having an EMP go off below that orbit just because someone wants to knock out the electrical systems on the ground is just going to cause havoc nowadays. First off what happens about the aviation sector?

Excellent content, as always. Your channel is so meaningful to me on a personal level. For years now, I've had some regrets about not paying attention to topics like physics, chemistry, and space back when I could have studied that stuff at my studies. Only later I realized that these topics are a passion of mine. Right now I'm studying to be a chef, which is also meaningful to me, but it's hardly the best place to learn about distant galaxies. These days it is possible to learn about almost anything simply with the Internet. However, I found it very difficult to teach myself about astrophysical topics this way. The content I came across suffers from two main issues (to me, at least): Either the language and concepts assumed to be self-explanatory would not be explained, making me feel like a dumb student at a boring lecture. The polar opposite problem was click-baity content, where everything would be repeated and dumbed down, possibly even being untrue to begin with. Entertaining, perhaps, yet not insightful nor wise. All of this to say, when I came across PBS Space Time randomly a few months back, I finally found what I was looking for. In this show, concepts are introduced clearly, without almost ever assuming you already know something (and in those cases it happens, you're referenced to another video covering that, lol). Then when the topic starts to get more complex, the stunning animations and subtle humor thrown in keep me engaged. I have great respect for the quality, clarity and aesthetic shown while explaining difficult concepts. I've had so many "A-ha, so THAT is how it works!" types of moments thanks to these animations. Matt and the team: I thank you all for consistently great content, which not only helps me study the things I love, but also keeps me entertained. I even find watching this channel helpful for my anxiety and depression. It is mind-blowing that getting to watch this level of content is free!!! And even though I have financial issues, getting some merch (or sweet swag, as Matt called it) is the first thing I'll do as soon as I can afford it. Thank you so much!!! Please keep making this stuff until the very end of ... space-time.

I'm glad you covered this. I remember the old series, Dark Angel, with Jessica Alba. The whole premise was the US was rocked by an EMP. And pretty much the whole world went dark, probably because of the EMP retaliation on the other side of the world. I remember thinking that the attack, which wasn't shown was very nondescript. Now that you described it, it seems much more plausible. I didn't know that it would be that effective. I never heard of the starfish prime experiment.

Same here. I had originally thought they took things a bit far with the effects and fallout. I had assumed some new-fangled fictional device was used, but now that dystopia feels all the more plausible, especially given current geopolitics.

For the moment it's a bit fun to think of it as, "that time we nuked space," but really it's just one of the other ways we could severely set civilization back by opening that bottle ever again.

Lol. This wasn't a surprise. We literally did it in operation Argus much earlier using small atomic bombs (not h-bombs) to measure the electron current bouncing back and forth from pole to pole. Starfish prime was an accident in terms of the target altitude, not a surprise.

Wasn't it always militarized? Wasn't the V2 (WW2 rocket) the first human made object in space? Followed by the Cold War space race... first by manned ICBMs going into orbit and later dedicated exploration vessels to put a flag on the Moon?

@@turtle2720 your absolutely right. However actually using weapons from space would be highly inefficient. It's actually more cost effective and easier just using surfaces based weapons. I mean we can already strike anywhere on the planet with ICMBs

Can we get a follow-up episode detailing the different ways to defend against EMPs and their associated costs and downsides?
@Howtheheckarehandleswit 2 ай бұрын
It's probably too simple for a whole episode of Space Time. There are two parts to the damage an orbital EMP can do: it damages electrical machines on the surface (computers, grids, etc), and it creates a radiation belt that damages satellites in a specific region. The way to protect against the damage to surface electrical machines is simple, easy, and cheap: just put proper fuses on things. The only reason not to do it is because it is ever so slightly more expensive (as in, 1 or 2 cents per device) to do so. There is simply no way to defend against the radiation belt other than to prevent the EMP from going off in the first place. Once it has, the belt is inevitable and there's no practical way to speed up it's decay.

well not unless you send a huge faraday cage in a roocket into the belt that can aborb the extra ionziting radaion radation and then discharge it down as elcical curent in a form of microwaves from a mcirowave trasmetr to a reciver back down somewher else into teh gronud into a battrey areay somewhere on the gronud that is but it would help speed it up a bit until it gets to ahrd to clean up the ahrd to get aeras you can't get at.

This reminds me of the 'snap' of magnetic fields around (and 'snapping' through) superconductors as they flux. I wonder if mini-EMPs are occurring all the time around superconducting materials when they cool... 🤔
@threeMetreJim 2 ай бұрын
My favourite emp generator is a low impedance coaxial line, charged to several thousand volts and discharged at one end quickly. The other end goes to an isolating capacitor and then an antenna. Peak power is around 250kW but decays quickly (over a few cycles of rf). It is actually an old military method that was abandoned and de-classified, but it works against modern electronics at a few metres distance (around 5m for unshielded stuff). I dismantled the test version, never to be build one again, after losing 2 laptops to it. Basically, a vhf spark gap transmitter running from 2xAA batteries.

Thank you for another great episode! How do the knocked free electrons that spiral along the earth's magnetic field keep up with the gamma rays that caused them, seeing the electrons travel a much greater distance in spiralling compared to the gamma rays that travel in a straight line?
@inochifumetsu 2 ай бұрын
They don't. The electrons aren't massless so they could effectively never keep up with the gamma rays (at least, if they do for even a short period of time, it's not very long -- see cerenkov radiation). It's not really about path length. The thing that keeps up with the gamma rays is the EMP *generated* by the spiralling electrons. The fact that they're spiralling is important because it results in a changing electric / magnetic field (they're constantly accelerating because they're travelling in a circle) -- that's the definition of light, which is what an EMP *is* -- so the EMP (which is light) is what's keeping up with the gamma rays (which are light) -- they're just different frequencies of light. The EMP can make it through the atmosphere and is a frequency (probably in the GHz range? Though I'm not sure honestly) which will impact electronics, the gamma rays can't make it through the atmosphere and.. well they *can* affect electronics but not the same way (nothing at all like an EMP).
