      Hate to break it to you, but short of something sudden like our sun exploding, getting directly hit by a cosmic ray or giant asteroid, it’s incredibly unlikely.

      We have reached a technological point where we could save ourselves from our own extinction, caused by us or not. It’ll almost certainly be a tiny fraction of today’s population though, but enough will survive to avoid extinction

        That technology requires massive manufacturing capacity that requires civilization. When water and food become scarce from a changed climate, there goes that.

        We won’t go extinct for a time, agreed. We’ll cling to our hardened structures and aging tech for as long as we can.

        But humans thrived on easy mode. In a climate we evolved to thrive in. Without that, we’ll become subject to nature’s whims once again.

        This is precisely why “we’re going to colonize Mars” is a hilarious pipedream. We couldn’t make a practically infinitely forgiving environment that automatically recycled our waste, water, and air work. We stressed it as hard as we could for as long as we could until it started pushing back, yet we only increased our attack.

        A few peak humans growing potatoes on mars is a cute “yay humanity” moment. But you’ve met us. A colony of hundreds, or thousands, some born into what would inevitably be a highly class segregated system that demands their servitude, given the private profit egotists now in charge of such things, where anyone making a mistake or having had enough easily leading to boom everybody dead try again? Yeah, that’ll go swell.

      • The Yellowstone Caldera erupting would probably do it, too. Also, a sufficiently big meteor, a rogue planet, or black hole. All would are beyond our current level of technology to survive or avoid. Or a local supernova, although there are no known likely candidates so that one is less likely.

          With meteors it isn’t if, it’s when. The question is whether or not we’ll be ready for it when it happens.

            We’ll let it hit us as 2 superpowers argue and threaten one another over who gets the mineral extraction rights.

            I guarantee it.

          Technically the cosmos are moving in such a way that our entire galaxy could collide with another celestial body at any moment if it were moving at sufficient speed relative to us, and we might never see it coming because the speed of light is only so fast.

            This, and space is huge, it’s really unlikely to get hit by anything. It will happen over infinite tescales, but I’m not as worried about it as I’m worried over another work email.
