How The Earth Got Its Magnetic Field (And Why It Might Not Protect Us Much Longer)

[@kimberlyperrotis8962]

I wish you had mentioned US Naval Captain Harry Hess, a geologist in civilian life, who sailed many missions back and forth across the Atlantic during WWII. He had the brilliant idea of towing a magnetometer behind his ship and recording the data. This was the discovery of the strips of basalt with alternating magnetivity along the mid-Atlantic Ridge. This discovery, along with other significant ones, led to the formulation of plate tectonic theory at the famous Asilomar conference in 1970. There has been an accumulation of evidence to support this theory, one of the most important of all science, in the 50+ years since.

@PW: I agree, although part of me wishes the level of academic rigor was even a bit higher - I keep seeing certain topics, events, and theories that get over simplified or glossed over, perhaps out of concern for overtaxng the limited attention span and intelligence of the snowflakes among us. Personally, I'd rather focus on those who are able to sustain intelligent and informed conversation regarding the material at hand ... but that's just me.

[@derreckwalls7508]

These videos are aesthetically pleasing in every way - the information is perfectly arranged by explaining the question so that you understand what's being asked, the answers contain easily comprehensible science, the narration is expressively soothing to hold your attention, the video and graphics are beautiful and explanatory, and the editing is seamless. Wow! This was a delight, and as close to perfect as you can get.

[@derreckwalls7508]

@LTrain 45 🤔 Artistic and aesthetic are not the same thing. I don't think they were trying to be artistic, but having a sense of aesthetics is necessary in any creative endeavor, especially in teaching where logical presentation has it's own intellectual aesthetic beauty. Plus, research proves that we learn better when our emotions are involved, so a straightforward, dry, unstimulating presentation would not be as effective. It also seems you are a rare exception considering the profusion of compliments the video has received, but you're in good company. Many geniuses deplored idle entertainment and lacked any appreciation for artistic pursuits.

Always found it absolutely fascinating how skip would be hitting so hard that local traffic was nigh impossible, and then boom all of a sudden dead quiet and no skip at all for quite some time and local traffic was eerily easy. Me and my best CB friend also got to work "short skip" from Michigan to Quebec during the big geomagnetic storm of 1989, which was a sight I will never forget. The sky looked 100% like the end of the world had come, with red and green aurora filling the entire sky in a rippling starburst shape and bright enough to read by clear till about 4AM.

Another top notch video. The narrator is a natural, with a voice made for narration, and the researcher really knows her stuff and has a way of presenting them to people with no scientific background in a way that is accessible. Kudos to both! The one small "thing" (not exactly a "beef", more of a "pet peeve") I can object to, but this is not your "fault" alone, everyone somehow does this (maybe it is the "legacy" of the American TV of the last 50 years?); speaking about how the next "super flare" COULD wipe out our electronic infrastructure - and it COULD! - but making it sound like it WILL, 100%. Since it happened once it will happen again BUT many things have to "align" perfectly for a repeat performance (the intensity and duration of the flare, the alignment of the Earth relative to the Sun at a specific point in time, the speed of the ejecta, the list is quite long). I guess in, say, one thousand years it will happen again but can we say for sure that the NEXT one is going to "kill" our civilization? I guess not. Still, this minor "thing" of mine aside, a great video once again!!

Radioactive materials like uranium and thorium tend to be heavy. Could they have settled into the core and now heat it by radioactive decay?

[@Merennulli]

They have indeed done exactly that, but they aren't the main cause of the heat. Just to be clear, though - they aren't in the core, they're in the upper mantle and crust. The heavy elements don't bond well with iron, so they don't sink as deep just due to the molecules they form being lighter than the molecules iron forms.

[@FloozieOne]

Apparently the Earth has been though thousands of these "wandering reversals" over billions of years and while they could have damaged the DNA of some plants and animals it certainly hasn't resulted in any extinction-type of events. Now, however, while animals that use magnetic fields for navigation would be severely affected the main danger is for humans. If the electrical grid should be destroyed, which it almost certainly would be, mass starvation would occur. Estimates are that it would take two decades to rebuild it due to the fact that all the components, (making steel, wires, rubber or plastic components, circuit boards, dynamos, etc.), require electricity to make. Trucks can't run without gasoline and that requires electricity to make. Only a tiny percentage of people live within walking distance of a food source such as a farm and those places would be overrun or brutally defended. All that said, I don't see that getting excited and worried over the possibility of a catastrophic flare is realistic or productive. The current warming of the planet is potentially far more destructive and is very real; we should concentrate on that and simply try to prepare for a flare without getting too worried about it.

The fact you seriously believe warming of the planet is more dangerous than a Carrington type event scares me more than anything. There is zero chance of that being the case. This is far FAR more dangerous.

I really enjoy your channel, thanks. During my education as a geologist in the early 80’s, the hypothesis for the generation of heat in the inner core was the entrainment of heavy, radionuclides in the core. During the early formation of the earth, the heavier elements were mostly concentrated by gravitational differentiation into the inner layers of the planet. As these radionuclides decay, they produce heat energy, thus powering the convection of heat in the liquid outer core.

As for the concentric spheres of earth's interior, I am reminded of Don Scott's model of a Birkeland Current as counter-rotating concentric rings(magnetic flux tubes). These structures are a type of double-layer seen in a plasma where charge separates(Alfvenn). Two currents can produce a pinch effect, Faraday observed this in physical wires and has been replicated in plasma labs and produce a plasmoid, a tiny but highly charged ball of energy which draws heavy elements to its core with lighter elements on the surface. This self-organizing ability of a plasma is integral to the development of life, in my opinion. I posit that it is a plasmoid in earth's core fed via the incoming electrons at the poles that produces the 6000* temperatures. And the concentric spheres are a product of double layering seen also in the chemistry of earth's atmosphere. Speaking of Birkeland, it was he who took those Terrallas, the magnetized ball and put it in a vacuum chamber, via the experiments he produced the rings of saturn, the auroras and posited electric corpuscles in space(solar wind). Taking this a step further, the Safire project has by manipulating these double layers produced 14 times thermal over-unity. We live in interesting times.

So far I believe the only reason for the category of a 'solid' core is because of earthquake wave readings that bounce off that layer. There must be questions?

What if a wave simply bounced off a layer going a different direction from the Crust, or actual rotation of Earth?? Or maybe the core has an extra strong and very low pulse, would that interfere with an Earthquake wave?

Most global communication is handled via extremely long underwater intercontinental cables. Those cables are shielded quite nicely by the ridiculous volume of water that we call Oceans.

[@hwplugburz]

I remember reading something about magnetic anomalies at sea long ago.. that the field strenght is weakened, and also reversed in polarity some plases, the moest famous and studied of these was somewhere soutwest of South-Africa i think,, and there was a theory that this possebly could be an indicator of exatly what you describe in the later part of this video... (total polarity reversal). I have a hard time seeing myself live long enough for this to be a serious problem within my liftime tho... But a direct hit from a superflare, protuberanses and a corona mass ejection is ofc an other matter. It would realy hurt humanity today! We, as a sosiety, are much less resilient to technology-faliures today, then we were in 1859. Love your videos 👍

This is what I call a great content, thank you so much!

This is probably what I worry about most, as far as impactful events. If you sit and imagine what would happen if all the lights go out, and all electronics were to get fried.. we'd have to rebuild everything, from refrigerators to phones, to the equipment and machines that make them. Everything we know requires electricity. We treat it like an eternal life force that will always provide, but in actuality it's far from guaranteed and highly susceptible to nature. For most people its sudden loss would be the equivalent of taking a newborn baby away from its mother and telling it it has to survive on its own. This is how dependant we are on electronics. Everything. Everyone in the world without electricity for a long time, the dire consequences and real possibility of this should make the world concerned with having a safety net, but no one sees past their own little bubble.

Your stuff is legit man. I love it. Keep it up.

An excellent channel. I just watched all 11 videos. Will you be doing on on the Great Oxygenation Event?

[@HistoryoftheEarth]

Yes, soon

[@KateeAngel]

@@HistoryoftheEarth don't forget to make a distinction between anoxygenic and oxygenic photosynthesis, please. I am tired of hearing again and again in documentaries and other videos the false equivalence between photosynthesis in general and the oxygenic one... They always speak as if before the event and before the cyanobacteria photosynthesis didn't exist 🤦, while in reality it had been evolving and powering the ancient biosphere for at least billion years before the cyanobacteria combined two photosystems in their cells and "learned" to split water. And there are many different variants of anoxygenic photosynthesis too, some of which like iron photosynthesis and manganese photosynthesis were probably very important in evolution of oxygenic photosynthesis. So, please, get it right 🙏 Sincerely, from a humble cyanobacteriologist

In other words, if you wake up one morning and your phone/coffee machine isn't working, but you can see auroras in the sky... prepare to eat your neighbors. ;-)

Edwin Horan I prefer to marinate my meat before cooking.

[@falkjanen5050]

@@baneofbanes Well, as your neighbors will quickly come to the same conclusion, this probably isn't the time for "slow cooking". Plus saving your oil and spices is probably a good idea because if you survive the initial slaughter, they'll be good for bartering. On the other hand, why not end things with a BBQ? ;-)

Wonderful!

17:38 I'm fascinated by this stock footage clip. The symmetrical shape in the ridgelines on the left side of the screen is too perfect. Was this CGI, what made those symmetrical lines! I've seen this clip used before and it always mystifies me!

[@kristiandent1798]

This is so good. It’s terrifying too.

[@benmcwhirter4566]

True gem of a channel.

[@hansjorgkunde3772]

Actually the magnetic needle points between two magnetic north poles, one over Canada one over Siberia. A secret hidden in plain sight. So the magnetic chaos with poles all over Earth is probably very close.

[@ebutuoy9071]

Absolutely awesome channel, does anyone know what the intro music is?

[@HistoryoftheEarth]

Contingency by Reynard Seidel

[@HouseofRecordsTacoma]

The magnetosphere predates stromatylits, with water in between. Do I see sequence of necessity here?

[@thawhiteazn]

I recognize the music at Part 4: Rachmaninov’s Prelude in c♯ minor. One of my favorite pieces to play, the last page or two is quite a doozy.

[@BoostBlix]

Guys the magnetic field just need someone to cheer him on, cmon join. MAGNETIC FIELD WOOOOOO ! Can I get your autograph!!!?

[@shawnwales696]

GMF, GMF, you can do it, GMF!!!

[@alpineflauge909]

awesome edit and awesome content, thank you

[@dathyr1]

Yes, if the magnetic poles reach a point during the reversal flip, the weaker magnetic fields could be a disaster for us. Also how long we would be in a weaker magnetic protection while the pole flip is going on. Hope I am not around if this should happen.

Dispite it's faults, the KZbin algorithm sometimes recommend gem of a channel.

@@NilsExp thanks :D

[@KingArthurWs]

There was a study on whether humans can detect the earth's magnetic field. Surprisingly, yes. Strong changes in magnetism in a room caused differing levels of changes in brain activity for different people. Veritasium did a video on it.

ı am incredibly happy to find this channel. thanky you much

Halfway through watching this video, and we're less than 5 minutes from a full solar eclipse. Timing!

as usual.. seriously well done
