Astrobiologist Breaks Down Apocalypse Scenes from Movies | GQ

[@andreaskiemer]

I have seen Grinspoon a couple of times already. Hes a rather reknowned astrobiologist and its his job to conjure up theories of other life forms when having a sample size of 1 (life on earth) for his thoughts and experiments. So being open-minded is a big part of his job. Hes also a quite good musician by the way.

He’s not just scoffing and saying “it wouldn’t be like that at all”, he’s thinking carefully and taking the time to choose his words. I so appreciate that. Edit: another thing I love is when there’s a person on the other side of the camera asking questions. The back and forth adds another layer to it that makes it. . . more casual?

@@diegestive4167 the standard US nuke here in germany is 250 kT. It's like 16-20 times Hiroshima. Some say, little boy was 12.5 kT, some 14 kT, some 16 kT. Hiroshima was a City with ~250.000 people. 1/3 died immediately. So, you can imagine, this 250 kT bombs are capable to destroy larger cities and kill the majority of the people there. Ofc. There are stronger nukes. The strongest was the Zar bomb, 50 mT - 58 mT, so 200x - 230x this sandard nuke, and like 4.000x Hiroshima. The strongest US bomb was like 1.000x Hiroshima. Because there are not that much cities big enough for such a bomb, and because it is more efficient to use a number of smaller bombs on a big city and spread them instead of one huge bomb, most are 250 kT, but lot of 500 kT and 1 mT bombs are out there, too. And smaller bombs, tactical nukes with 50 kT or less, some like Hiroshima, some smaller, like 5 kT - 10 kT, to deal with an army and use them on the battlefield. You can shoot some of them with artillery. The russians have the most nukes, but because of radioactive decay you have to replace the nuclear material very often. That costs a lot, and you need to be capable to produce enough new nuclear material. The russians aren't even capable to produce enough modern stuff for their regular forces, and maintain it, what you see in ukraine now. 60% of their rockets are misfiring. So, if you think about this, the costs of maintaining that amount of bombs, what USA has to invest, what russians put into their army (a lot, but far less with more nukes and this situation even for the regular forces), and that nukes are a weapon you dont want to use, and if you think about the fact, you dont need that much, to scare someone of, too, you can imagine, most of their 9.000 bombs are probably defect. Could be like 90%, or more, which means like 500-1.000 bombs, still. I could imagine, most tactical, around 100 "standart", so very efficient, like 1-2 of them per 1 million people in a city, spread out, and a few very big bombs, 10 mT or more, which wouldn't be very efficient to destroy cities, if you can destroy more while using less nuclear material and needing less powerful bombs, if you use still powerful but spread out bombs, but which should be very impactful regarding moral of the population. But i doubt that the russians have more than a fraction of their nuklear forces ready, or are able to make them ready. But stil, they should have many nuclear weapons ready, compared to other nations. I think, USA probably is capable to maintain all of their bombs, so more than 6.000. Most tactical or standart, i would assume 250 kT - 1 mT, maybe lots of 100 kT bombs (still 6 - 8 times Hiroshima, and you use like 1 per 100.000 - 250.000 people, or on cities with 250.000 people or less), because of efficiency, and some big bombs, like 5 mT - 10 mT. The other nations with nuclear bombs have something in the hundreds, like chine, Great Britain and France. Some have around 100, some less. So, all together around 2.000 bombs. That means, around 10.000 nuclear weapons ready for use worldwide. I would assume all together between 1 gigaton and 10 gigatons (worst case). Spread out, if you would try to destroy as much as possible, spread them out, use them on the biggest cities, and the tactical weapons on cities like Hiroshima, i can imagine that they can kill maybe 1/2 of the human population immediately (worst case), more likely around 1/4 (not enough really big cities worldwide for this number of nuclear weapons to kill and destroy more), but fallout in a big area around the cities, and radioactive sickness would kill far more in the next 5 years, worldwide, with this number of bombs (just look at Hiroshima), and more would die because of the nuclear winter and what it causes, so no food, for example. Contaminated water, worldwide. Destroyed technology because of all the EMPs, so no more electronic technology. No medicine, but plagues/diseases. No communication, no organisation, not enough left for civilication, so not enough food production, ressources, no chance to manage the supply of the surviving population, and everyone would fight for the few food and ressources left. This should lead to the death of most humans as result of a scenario like that in the years after a big nuclear war, with just a few million left, worldwide. And i think, there would be places, where some of the people would survive with hightech and would manage to maintain it, but most would live like before the electronic era, most like before the industrial revolution, like in medieval ages. I think, they could use the ressources like iron and steal that are there, in buildings, for example, and wouldn't need to mine them, especially because there would be just millions left, but all the ressources. I dont think all humans would die, but most of them, and the people left would mostly live like in the medieval, but i think mankind would manage to survive and develop, get the technology and civilication back in the next couple of hundred years, but faster than the first time, because of far more educated people now, compared to medieval, retained knowledge, technology that survived, and things like that. But to really wipe out mankind it needs more, imo. Like a huge volcano, like toba 50.000 years ago, or more. Or a big asteroid or comet, but by far not as big as 65 mio years ago. More like the impact 58 mio years ago in greenland. An asteroid that was around 1 mile big, 1,5 - 2 km. Or around 15 mio years ago in germany. Same size as the grenland impact. Maybe it needs something 2 miles big, maybe even 3, or 3-5 km, so something huge, but by far not something like the dino killer. Things you have every 5 - 20 million years. So, i think to wipe out mankind completely, you need something like this. But it happens, and often enough. Yellowstone is bigger than toba 50k years ago, and could errupt. Asteroids that are big enough come every couple of million of years, and that is not that rare. A gamma-ray burst killed most live 440 mio years ago. Could happen again. Lots of things. We have to see.

The visible skeleton during a nuclear blast is actually very realistic. The blast is so bright that you can see right through flesh.

[@s000162017]

I agree with the pavement becoming fields slowly, but I'd add that I feel it would happen exponentially faster in colder climates like northern cities that have much colder & more regular snow & freezing temperatures to allow water to freeze & exacerbate the cracking & crumbling of the roads & parking lots than the lower warmer areas.

[@mehere8038]

would also depend on original building standards, some countries have super high standards & roads etc are built to last decades, while other countries build them with the intention of only lasting a decade or so before repaving. Depends on if their economy is set up for one off high payments & value for money, or ongoing job creation & cheap initial spends. Would also depend on what plants were present, some plants can break through anything. Those plants are generally considered invasive weeds. Places that have failed to control those before the disaster will be more susceptible to them breaking down human stuff. Animals will be a factor too, elephants reclaiming cities will be very different to deer doing so. Rabbits burrowing under & elephants on top would presumably be hugely destructive, especially on roads built only to last a decade. Add some squirrels burying seeds of invasive plants in there & things could break down pretty fast. WOn't end up with nice long grass though, will end up with the invasive plants dominating & strangling everything

The reason whales didn't, and we wouldn't, develop gills is because the oxygen content is too low for our metabolism. We would have to sacrifice something for it, likely brainpower in our case.

[@mirensummers7633]

That's not the only reason, and there are ways around low oxygen concentration. Oxygen carrying capacity is higher at lower concentrations in people who live at high altitudes than the rest of the population, and fetal haemoglobin has a higher affinity for oxygen than adult Edit: so what I'm trying to say is it's very plausible that evolution can find a way of adapting to that

[@tigermunky]

Haven't you read KZbin comments before? I don't think there's much brainpower to sacrifice. A lot of people would get by fine on half the amount of oxygen.
