    • @nebulan

    • @di99utpe
      @di99utpe Před 2 měsíci +626

      I'd say the lack of food and water will kill most. So some place where the survivors of the outer layers can live of the land. (All infrastructure, such as logistics, sanitation and modern agriculture will be gone for a loooong time)

    • @brandonkoh8361
      @brandonkoh8361 Před 2 měsíci +588

      Id say probably a large city in europe that has a seriously robust and international train network. Plenty of farming in europe, trains can ferry a ton of passengers and food. Many coastal cities are within spitting distance of most other countries and thus have ships, containers etc.
      Edit: Actually now that Ive thought about it, the biggest factor for fatalities would likely be just that the people in the middle of the crowd of 8 billion people are literally unable to walk and will eventually die from the elements and thirst. This alone would likely contribute many billions of death since you just cant walk through people.
      Therefore an area with mild climate that can permeate the crowd with the largest number of deep flowing fresh water and relatively clean rivers would probably be a requirement. This allows a large number of people to gain fresh water as well as provide people a mode of transportation (floating in the water is better than standing for a week). Would ideally need to have a few main cities on the path of the tributaries, ideally with rail networks, or port cities.

    Everyone who was in surgery or on life support probably died soon after they were teleported. Everyone who was deep diving experienced rapid decompression.

      For this coordinated jump to be possible, everyone would need to know what to do. So we can assume that the wizard would send everyone like a telepathic message 5 minutes earlier or so. Enough time to leave the water, put on some clothes ect. But sure, the people in surgery or on life support would be screwed. And it wouldn't even help if we say we exclude handicapped people from the scenario, because then they would be left behind abandoned and helpless.

    Some additional thoughts/questions:
    Standing in the exact middle of that massive crowd, shoulder to shoulder to each other, would/could oxygen become an issue, given that this is now basically an rhode island sized lung?
    If panic breaks out among the claustrophobics and people start to run/push around, wouldnt this affect general survivability a great deal?
    Could you even survive anywhere near the middle? I mean it would take quite a while for enough people to move so that the middle bunch even get the chance to make any step towards water/food?
    Based on current statistics, on average between people being suddenly put on that place and people finishing the jump, how many children would be born right then and there? Contrary, how many would die of old age?

      Whatever impulse the earth got when the humans jumped off, gets cancelled back the moment they land.... Unless someone manages to get yeeted out on at escape velocity. The orbit, the rotating, everything stays absolutely unchanged.

    Every time I hear this question answered, there is no mention of the fact that it wouldn't matter how much people weighed compared to the Earth, the orbit could never be affected by such an event. The mass of people and the planet would momentarily move away from each other, then back toward each other due to gravity. There would be no net movement one way or the other.

      It would matter though. If people weigh somewhere near the same order of magnitude as the entire Earth, the amount of energy released by the friction and shock of the jump would be astronomical. I don't know how much energy could realistically escape within those conditions but it's not absurd to think that enough could escape that it would have an effect, at least until you do the math.

If you speak English or Chinese, you should be able to communicate with several people around you barring bad random luck. English is spoken by 1.4 billion people, so it's a 1 in 5.7 chance that one of your neighbors will speak it, and Mandarin has 1.1 billion speakers, so it's a 1 in 7.3 chance. Other languages like Hindi, Spanish, Arabic, French, Russian, and Portuguese (all with over 250 million speakers) will have somewhat decent chances, although they are all between 1 in 10 and 1 in 32.

    this was always my favorite what if? because of how much of a world it built, and how many ideas could stem from such a simple question

    I think the outcome of most of these What If questions can be summed up as "a fun way for humanity to face near extinction"

    I keep hearing the theory that if everyone in China jumped up and down at the same time, it would make a big enough seismic event to cause a tsunami in California. I always thought the numbers for that are out by orders of magnitude.
    But at university, there was a variation that seemed slightly more plausible: suggesting that if everyone in China sneezed at the same time (and presumably in the same direction), they could send a wave of air pressure that would cause a noticeable breeze on the far side of the pacific. That one made me wonder if it could actually be plausible; but I don't know the right kind of physics to estimate that one. Fluid dynamics is weird, and possibly incompatible with common sense.
    But a little while later, someone misheard a variation of that debate, and it somehow mutated into "if everyone in China broke wind at the same time" … how would you even search that?

      I don't think that is how physics work. If you buy 100 (or 1000) normal fans and put them up in your house, they will not have the effect of a hurricane, because their effect won't like, erh, add up.
      But I do wonder what the result would be if enough ppl in an enclosed space broke wind.(with all the gas being released)

    2:55 - "Any two people who are unlikely to have a language in common." Really? I'm not so confident about that. A lot of people speak Mandarin. A lot of people speak English or Spanish. I don't have the numbers on-hand right now, but I'd wager that among the 6 (?) people immediately around a random person, they would have a good chance of finding someone with a shared language.
