Oppenheimer’s “Terrible Possibility” - Atmospheric Ignition

Fifteen seconds before 5:30 a.m. on Monday, July 16, 1945, J. Robert Oppenhemier and his team of Manhattan Project scientists ushered in the nuclear age. And thankfully, after the Trinity test, the Earth was still there. This [HALF-LIFE HISTORY] is the true story of the day we almost set the world on fire.

@@captainhoratius8192Yeah, there's a big difference between pointing the gun and pulling the trigger. We all know it's gonna kill someone if you shoot them, but almost everyone has a panic attack their first time actually doing it.

[@bavettesAstartes]

It never sunk in how serious that first line is until now. "A few people laughed, a few people cried, most people were silent." I can imagine people laughing at "the new toy" they got. I can imagine people crying over this new horror they created. But most important of all, I can never imagine myself doing anything other than just standing there and staring at it, like a deer in headlights. I can not imagine myself laughing or crying. Just looking. Paralyzed by would-be fear or the awe of all the possibilities.

@@davidaugustofc2574 It's less about intelligence and more about processing power. It doesn't matter that Oppenheimer was likely one of the most intelligent humans to ever exist even up until today; no amount of human intelligence alone could perform 2-point safety calculations on a nuclear weapon's pit, or imitate computer-generated imagery.

Groves: "They're saying there's a chance that when we push that button... we destroy the world." Oppenheimer: "The chances are near zero." Groves: "...Near zero?" Oppenheimer: "What do you want from theory alone?" Groves: "ZERO, would be nice!" Honestly my favorite part of the movie.

[@Michael-kp4bd]

I haven’t finished this video, but I believe the well supported calculations showed that it was a certainty that the atmospheric chain reaction could not happen. I don’t think they truly gave it any percentage chance of happening by the time they had built the Gadget. However, the mere hypothetical, plus the fact that it was the first time actually putting the full weapon to test… it still feels like anything unexpected could happen. But yeah, we then went on to produce nukes literally 2 to 4 *thousand* times as powerful as the Trinity test, so scientists knew the exploding atmosphere situation wasn’t theoretically possible. So I think it’s ahistorical, but made for a good line addressing Teller’s “terrible possibility” consideration.

[@leowic]

​@@Michael-kp4bdwhat is terrifying are all the things they didn't consider, which COULD have been factors. Daughter compounds from contamination of the air, the vaporised shell of the device, the interaction withe the geometry of atmospheric layers and the ground. True, HAD they taken all these factors into account they would have done much more work to find the same result, it was 'safe'. However, the fact they rolled the dice on a bunch of factors that potentially could have pushed the safety factor to near zero should scare the shit out of people.

Is it me or does anyone else think Kyle should have his own TV documentary series covering subjects like this? These vods carry as much weight as legendary broadcasters such as Sir David Attenborough.

[@bearcubdaycare]

Knowing I may be flamed for saying this... KZbin has proved to be the better replacement for TV documentaries. Don't get me wrong, there were some awesome TV documentaries. But amidst the staggering amount of mediocrity uploaded to KZbin, some really amazing stuff eventually rises to the top...this channel, Hossenfelder, PBS Space Time, Three Blue One Brown, Mathologer, The History Guy, Tom Scott, Technology Connections, the list is long. More excellent content has become available than on TV, on more topics, from more excellent creators. Which was the promise long ago of the internet, and it seems to have manifested. (I'm not adverse to paid documentary outlets like Wondrium with its enjoyable series on the Celt's, or Nebula or such. I happen to subscribe to both. But the enormous volume and diversity of the more open KZbin has its benefits, not necessarily to the exclusion of the others.) (To be honest, I haven't watched TV or cable in a long time. I'm just vaguely aware that they still exist. I'm basing this on decades past.)

[@BM-jy6cb]

No, because then the bureaucrats, marketers, and arts graduate producers would be all over it and we'd end up with exactly the kind of dumbed-down crap full of padding and "celebrity" presenters taking up most of the budget. Kyle's videos are perfect just as they are, thank you. BTW, David Attenborough has turned into of the wealthy climate alarmist hypocrites. He's made his career, loads of money and life satisfaction flying large production crews all over the world and has now taken to sanctimoniously lecturing the rest of us to cut back on our daily travel or annual holiday across the Channel.

[@cloudkitt]

that c-squared term is a real bastard

[@Grizabeebles]

And to think that sci-fi media just throws around the idea of anti-matter based weapons. Photon Torpedos in Star Trek can contain up to 1.5 *kilograms* of antimatter. When combined with an equal amount of matter, 6000x as much matter as would turn into energy as the Little Boy explosion. On the one hand, this is "only" a 64 megaton explosion. On the other, the characteristics of the explosion have the potential to be completely different than the Trinity test. If all the antimatter isn't consumed immediately at the point of ignition, it *will* continue to annihilate with any atoms it comes across as the blast wave propagates outward.

[@StrikeNoir105E]

Watched some videos of the Beirut explosion a few days ago, which is considered the largest non-nuclear explosion ever releasing 1.1 kilotons worth of energy. The fact that it took such a massive amount of physical explosive to create such a relatively "small" blast puts into context how truly amazing a nuclear weapon is, as nukes can release thousands of times more energy in only a fraction of the size and volume that the explosives in Beirut took up.

While I can appreciate the drama of "not zero", considering how often people take science's "well... not zero" to mean "them scientists are WRONG cuz I watched this KZbin vidyea", we probably really should educate everyone on what scientific speech is about. (ie... their 90% surety is more supported than most others absolute certainty)

[@anteshell]

@@Ryukachoo Not at all. Mathematically any non zero possibility is still possible. It is simple as that. There is nothing you can do to counter mathematics with colloquial dismissive off-hand phrases like "basically" or "practically". Non zero is always more than zero, and as such, a very real possibility. A living proof of that is you having made that one particular comment at this particular time and location in this world and universe a whole. A tiny, infinitely small chance that all the atoms and forces ordered themselves to make it possible, yet here you are watching this and commenting. But what comes to the "cheapen the complex emotion"... I don't think they cheapened it. It is impossible to convey feelings accurately through movies if the audience is vastly different reference group than the people whose feelings are tried to be conveyed. Accurate mathematical proofs and probability chances would have made the vast majority of the audience to dismiss them in confusion or lack of understanding. Everybody understands the dramatism and impact of "non zero chance" to destroy the world, but very few understands (you included as you showed in your comment) that literally ANY non zero chance is still a chance, no matter how small. Thus, I think they made the right choice to use such vague expression. It is much more easy to understand and subsequently empathise with what the scientists were feeling.

[@kyleespinoza7201]

The thing that made this movie truly, truly special to me was the conversation between Oppenheimer and Einstein at the end. It didn't really matter that Trinity didn't instantly destroy the world at detonation, because it unleashed two very different sets of chain reactions. One never could ignite the atmosphere, but the other could still cause the extinction of the human race, and short of humanity collectively getting our shit together and completely eradicating every nuke on the planet forever, that sword will always be hanging over our head.

[@dormantlime215]

Einstein famously also regretted the only part he ultimately played in the nuclear bombs, which was writing a letter urging the US government to complete the nuclear program. After the bombs were used in Japan, and learning that the Germans were not in any way as prepared to create a bomb as we were, he said had he known those two things he never would have penned the letter at all.

[@Techno_Idioto]

We have that sword of damocles hanging there still. The rope that holds it frays and snaps as time goes on. Perhaps, if we act now, we can stop it from falling onto our heads. Otherwise, our extinction may come sooner than we think.

[@QBCPerdition]

@@Techno_Idioto That sword will always be there. Even if we destroyed all of the nukes on the planet, the knowledge to recreate one would still exist. I'm as pro-disarmament as anyone, but we'll never put that genie back into the bottle

I was fortunate enough to watch Oppenheimer on it's release date and I will say that it never really struck me that they actually had legitimate concerns over igniting the damn atmosphere with Trinity until I watched the movie. Your video only cements the awestruck nature that the detonation in the movie mimics, and how much of a grim tone it actually had on people who literally built the damn thing. Just another phenomenal video essay, Kyle. Keep up the Half-Life History, it is hands down my favorite thing you do on this platform.

[@misskitty2133]

I love science and found chemistry & physics came easily to me in college. How I wish I’d changed my major and gone on to Cornell like my professor urged me to do. I think I would have been a very enthusiastic scientist! But my 22 year old stupid brain took over; I stayed because I was head-over-heels about an idiot named Peter and couldn’t bear the thought of being so far away from him & breaking up inevitably. As fate would have it, the relationship turned volatile as he descended into alcoholism and I did move away 2 years later. And now I’m 65 and run a non-profit cat shelter. So, vicariously through your incredible videos, I can be a scientist. I love your videos!! They’re well put together, factual but leaving plenty of room for speculation. It’s so much fun!

[@frenchfriedbagel7035]

I haven’t watched the video yet. It’s about the possibility of igniting the entire atmosphere on fire, right? They did a lot of calculations to make sure it wouldn’t happen.

[@cortster12]

Quickly dismissed, I believe. But the possibility made them take it seriously at first.

[@inyn_k]

The best thing I think about this theory is that ignition of Atmosphere is really possible. It's just that it would require a lot more energy and higher percentage of deuterium atoms in the ocean. (I read that somewhere) Now let's say we do ever need to terraform a planet by burning the crust, just like how we theorize about terraforming Mars, then we would only have to detonate a powerful enough nuclear bomb on the right planet to burn the whole planet down. This does feel like a super villain plans though😂

[@5roundsrapid263]

The Genesis Device?

[@WE-te3vp]

It's a blast on a whole another level

[@eroraf8637]

It really isn’t, though. As Kyle said, you would need the equivalent of 1.5 million kg of fissile material reacting with 100% efficiency. That’s basically a sphere of plutonium over 5 meters across, and you’d have to assemble that from many subcritical masses AND ensure that the whole thing goes prompt-critical at basically the same instant. Even if you tried to stack thousands upon thousands of more practically sized nukes together, you would have to detonate them all within microseconds of each other, considering that a mere 1-megaton detonation (57 kg of plutonium) produces a fireball that exceeds 100 meters across in less than a millisecond. It’s just. Not. Possible.

could be easier or harder on some planets. Not much atmosphere left to burn on Mars!

A large portion of the general public refuses to take vaccines. Why would we tell them there’s a .0001% chance of destroying the world. They would just hear destroying the world and go French Revolution on the scientists.

[@bookworm3005]

It's an interesting thought experiment tho, what if after the test, the US hadn't dropped the bombs on Japan and instead went with the land invasion. Millions and millions more dead, and who knows who would have won WW2. If *that's* when we learned it all could have been avoided by using the bombs, think of the uprisings against the US gov that would have caused.

[@josephmother2659]

@@bookworm3005what do you mean “who would have won world war 2”? The war was legitimately over everywhere but Japan and wherever Japan has sent its troops. The entire world fighting one country would have ended almost immediately, obviously with large casualties depending on how much the Japanese wanted to preserve their pride. In my opinion obliterating hundreds of thousands of civilians is the ultimate abandonment on humanity. Whether Truman, Oppenheimer, and anyone else felt like they had to or not, they are complicit in an unforgivable action that exemplifies more than anything else how humans drift more and more towards destroying themselves and anyone who gets in their way

It always saddens me when I see people mistrusting scientists because they have the crazy-evil-scientist-trope in mind. Of course we shouldn't trust anyone blindly, and everyone should think for themselves. But I think it is actively harmful when new technologies and insights that could make the world a better place get dismissed by the public, because movies taught us to fear the things we don't understand...

[@THEJPIndustry]

@@Hendrik_F for some reason I completely trust science, and normally scientists, like I know that they have to run around a few million tests before doing anything. So I guess my main mistrust is in scientist's building a bomb xD or I guess any Russian engineer scientist's I guess everything that could be seen as evil scientist's.
