    Every single nuke in the world pointed at the same spot could not achieve anything even close to this.

    This would require an asteroid/comet impact … an order of magnitude, or two, or three, more destructive than the chicxulub impact that wiped out the dinosaurs.

    The entire chicxulub impact crater is about the size of ‘Mound Island’.

    An impact this huge would probably shatter the crust of much of, if not the entire planet, and turn the entire atmosphere into fire.

      No, but they could create a thin glass crust over the whole area that would accomplish much the same effect.

      That circle is roughly about 2000 miles across (according to rough measurements in Google maps), which is only about 2x the size of the Gulf of Mexico.

      But yeah, this would be a cataclysmic event.

      I don’t think there’s anything that could make a crater like that on Earth. Like, an impact big enough to leave a crater that big would render the entire crust splashy enough to fill it back in.

        Yeah… from what I remember of dicking around in universe sandbox and space engine a while back… yeah, an impact this massive would … well, now it makes more sense to model earth as a multilayered, viscous liquid, basically.

        You could end up with a ring system or possibly some minor moons, made out of ejecta.

        After basically the entire Earth has turned into ‘the floor is lava’ for… decades? centuries?

      No, sorry, letting arabs live is antisemitic. And that’s a bad thing to be. I don’t make the rules; i just uncritically accept anc enforce them upon those who cannot defend themselves and nobody else.

          If we want to be realistic, then if there was a nuclear explosion that big on planet Earth all the nations around it would be nuclear wastelands from the shockwave and fallout and the rest of the planet would probably be covered in ice from the nuclear winter.

          Most nation states on that side of the planet would be gone and the ones on the other side of the planet would at the very least be collapsing from the fall in agricultural production and subsequent wars of desperation.

    Whatever made that crater was an ELE. Bigger than Chicxulub.

    We have plenty of great filters to navigate:

    We end war, or we die.

    We restore the atmosphere and rebuild global ecology, or we die.

    We end stratified society and power disparity, or we die.

    Where are all the aliens? Fermi asked. The first question is, how do we navigate our way to becoming a space-faring, world colonizing species, ourselves? It’s turning out to be pretty difficult for the common hominid.

      Not to mention skynet. It always bothers me when people leave AI out of lists of x-risks. I guess it’s because a popular sci-fi movie predicted it would happen, so nobody takes it seriously. Or perhaps it’s just because AI is so unpopular now, nobody wants to devote any time to thinking about the ramifications of it becoming smarter.

        Courtesy of XKCD, long before we have to contend with unfriendly AI (we have committees of AI-techs working on this problem already) we’ll have to contend with someone like Musk or Bezos determined to own everything and capable of creating an AI-controlled army of killer robots.

        We’re not sure how rogue AI is going to manifest. We are sure rogue power-seeking humans exist all the time, and positions of power are commonly filled by them. (That’s the primary argument for election by sortition, or by lottery.)

          Ok, so to be clear, you’re saying that AI x-risk is already partially or even mostly bundled under “We end stratified society and power disparity, or we die.”?

            That is a good assessment. Yes.

            In fact, the race between capitalist interests to bypass safety and get operational AGI soonest is entirely about getting that power to be able to use it to hold everyone else hostage.

              Yeah, fair enough, I do agree that this is largely driven by capitalism, and if we didn’t have a capitalist society we would hopefully be going about this more cautiously. Still, I feel like it’s a unique enough situation that I would consider it its own x-risk.

      Which is illogical if it is supposed to be an epicentre of explosions. However, if it was Israel nuking everyone around… I mean, one ongoing genocide may not be enough for them.

    It looks much larger than the Chicxulub crater (~200km diameter 72 tera tonnes of TNT), this must be a exatonne explosion, I measured the crater diameter to about 3500km!

    It would take decades or centuries before the sky would clear after such an explosion, most likely resulting in a mass extinction event.

      Considering that we’re in the midst of the Anthropocene mass extinction event already, I’d say it would be a certainty. The only question would be how bad it would get. Given how much larger that crater would be than Chicxulub, I’m guessing it would exceed the “Great Dying” (Permian-Triassic extinction event) to take the crown.

      Edit: The Wilkes Land Crater in Antarctica, which may be associated with the Great Dying, was “only” a little over 2.5 times larger in diameter than Chicxulub and thus still way smaller than the crater depicted. That said, I guess a nuclear crater wouldn’t be associated with a flood basalt “exit wound” at the antipode the way an impact crater might be, so maybe it wouldn’t be comparable.

      it would also shatter tectonic plates, create rifts and reverse the directions some plates were moving, the asteroid impact you mention resulted in the Indian subcontinent (I’m simplifying a lot of things right now)

        Well, now you’ve piqued my curiosity. Got a link?

        The Wikipedia article I’m reading right now says that the Indian plate split from Gondwana 100 MY ago (33 MY before the Chicxulub impact), so that’s not the connection. Further down the page, it says that the plate movement might have sped up as it passed over the mantle plume from the impact that created the Deccan Traps (my interpretation, BTW; the science isn’t actually as settled as I’m making it out to be), but it seems to me that that wouldn’t change the “result” of the plate colliding with Asia and creating the Indian Subcontinent, only the timing of the collision.
