    Gamma ray bursts from celestial events such as a supernova. One of these - GRB 221009 released 1,000 times more energy in 5 minutes than our Sun has emitted throughout its 4.5 billion year life. GRBs from different galaxies have set off detectors on earth designed to detect nuclear explosions. One of these in our galaxy, pointed directly at earth could end all life on it. https://en.wikipedia.org/wiki/Gamma-ray_burst

      and Bostrom’s simulation hypothesis and Pascal’s wager, all subject to the validity threat “What alternative explanations are there?” and “How can I be wrong?”. All of these thought experiments are unfalsifiable. They can all be explained with different theories. They all rely on circular reasoning. They all anthropomorphize entities that maybe don’t resemble humans at all. They all fall for the mind projection fallacy. They all are prey to selection bias, because they cherry-pick scenarios among countless alternatives.

    Every study performed on insect counts has concluded that overall insect populations are declining, though there is not complete global coverage of data. One study in Germany found that the flying insect population had decreased by 75% from 1990 to 2015.

    A 2019 survey of 24 entomologists working on six continents found that on a scale of 0 to 10, with 10 being the worst, all the scientists rated the severity of the insect decline crisis as being between 8–10.

    Nothing scares me quite as much as the thought that I might live to see global ecological collapse.

      I remember a road trip to Poland to my grandparents place. The trip took around 10h by car over the german and polish highway.
      On the first trip the car windshield was plastered in little dead flying insects.
      The las time we went there (about 10 years ago) there was not even close to the amount on the windshield.

      My younger friend asked why some old cars had a piece of plexiglass on the front of the hood.

      I had to explain that thirty years ago, in this area, you would drive through enough bugs in a day to cover your windscreen. The bug shield would help deflect them. It was a pretty grim lunch after that.

      THAT is my fear. I’m watching the ecosystem collapse on my front porch. I could go on for a long, long time with my observations, both historic and recent, but the food chain is collapsing where I’m at. Wildlife populations are noticeably crashing from what I observed 4-years ago.

        When I was growing up in the 1970s there were thousands of lightning bugs at night. Any time going outdoors after sunset I could see hundreds of lights winking on and off every few seconds, in fascinating patterns that I loved to look at. Later at night the bugs would fly higher or stop flashing

        It was such an ordinary part of life, but movies and tv at the time don’t capture that very well .

        Now its gone, for most areas

          Saw a documentary about a Chinese billionaire on TV a couple of years ago. He was born poor in some village and worked his way up, owning dozens of factories now. He was super busy, grumpy to the people around him and very torn. Asked on camera of he is part of the solution or part of the problem, he couldn’t tell. Told us he misses the sounds of frogs in the evening, when he was playing with his friend in the forests and fields that are now industrial parks. Made me cry, what are we doing?

    Some species of snails are infected with a parasitic flatworm called Leucochloridium paradoxum, which has a life cycle that involves manipulating the snail’s behavior and appearance to increase its own chances of survival. The parasite causes the snail’s eyes to turn into worm-like protrusions, which are actually just the parasite’s own larvae.

    To birds, these worm-like eyes look like tasty little morsels, and they’ll often peck at them to eat them. But in doing so, they’re actually ingesting the parasite’s larvae, which then complete their life cycle inside the bird’s digestive system.

      I remember a story where Charles darvin was on expedition and saw a wasp stinging a tarantula and laying her eggs into the spider and it had the most grueling death. Something like that, and that’s where he realised that no god can be so cruel to make something like that. Now i have no idea if that is just a story or something that actually happened. But if you believe in any creator and see shit like that and still think: man that god guy sure has a funny sense of humor, you’re kinda weird.

        The larvae (possibly not quite the right word) eaten by the birds lodge in the international tract near the cloaca. The eggs they produce are passed out, and snails eat the eggs.

    Microbiology can be so much fun!

    Streptococcus pyogenes causes a flesh-eating disease (necrotizing fasciitis). This species of bacteria releases toxins that kill living tissue, so you better make sure that paper cut doesn’t get infected.

    Mycobacterium tuberculosis is famous for a bunch of different pandemics over the centuries. If you thought covid was fun, imagine coughing up blood.

    Clostridium botulinum is special, because it produces a very spicy toxin, so you don’t even have to ingest any living cells or spores of C. botulinum to get killed by it. If you do, you can even have your very own toxin factory inside you.

    Vibrio cholerae is another classic responsible for numerous pandemics. This one is a bit different, because it involves lethal amounts of diarrhea.

    Oh, and the scary bit? There are people who don’t believe bacteria or viruses exist. They actively oppose taking measures against these things. Humans can be truly horrifying at times.

        Another “fun” fact: it’s one of the biggest killers in the third world, especially of small children, and at some point there was a diarrhea magazine as a result.

        I can’t believe tetanus got left out here. It’s a common soil bacteria like botulism, but has the opposite effect if it gets in you. It makes all your muscles forcibly contract and cramp up until you die.

        Botulism is really easy to get if you can food wrong, because it’s the one abundant bacteria that will survive limitless normal-pressure boiling.

          Your immune system gives some protection against botulinum, but it doesn’t fully develop until about six months to a year old. This is why you should never ever feed honey to an infant. Bees will occasionally end up on the ground, picking up botulinum. There’s a very small chance of a trace of the bug ending up in honey. It’s not enough to harm an older child or adult, but even thst tiny amount can kill a baby.

            Yeah, it will basically colonise their intestines instead of the bacteria that are supposed to, and just poison them continuously. It’s especially a concern if you live near a construction site just because of all the dirt being moved around and exposed to air, IIRC.

            If we’re branching out into possible non-life, prion diseases like mad cow or kuru have a creep factor. You could be terminally infected already as you read this and not know until you start getting clumsy and confused years from now. Also kuru is spread by long-term habitual brain cannibalism, so that’s culturally uncomfortable.

              Well… if it means I’d die of lethal diarrhea immediately after being reincarnated, I guess it could be worse! Like having to live 6-7 decades with the knowledge that I may or may not, at one point, contract lethal diarrhea, and that I’ll just keep on coming back to this particular roulette wheel over and over and over again, being forced to play the odds in an infinite canvas of probabilities. You know what they say, the anxiety’s always worse than the thing-in-itself!

    Each year, is about a 1/2 of 1 percent the sun will give out a flare so big, it will not only destroy all power distribution to the half of the earth exposed, and destroy the internet there, but cut off food distribution, starving most of the population in any county . Last time it happened was in the 1800s but no stuff to destroy then. And food was local.

    It would be years before things were normal . Our current setup is literally doomed to failure for a random half of the earth

      There was a bit of tech around at the time - telegraph. The flare sparked fires in telegraph offices and shocked some operators. As in electric shock, not a big fright, though no doubt also that. Some operators disconnected their batteries and were able to communicate by the auroral current alone.

    If you separate the halves of your brain, they can operate relatively fine independently of each other, each controlling roughly half of the body. When one half does something, and the other half is asked why they did it, the other half will make up a plausible reason why they just did that action. There’s a theory that this is basically how your brain works all the time, just guessing why it did things, and potentially with multiple processes happening in relative isolation that aren’t consciously aware of each other.

      I find this kind of exciting actually because that suggests that our brain is already a hivemind with two minds melded into one. This opens up potential for expanding the mind in the future either through connection with other biological minds of even artificial ones by hooking into the corpus callosum. :)

    There is a possibility that the Higgs field isn’t at it’s lowest energy state, and that a random quantum tunneling event could drag the Higgs field to that lower state. In this unsettling scenario, a bubble pops into existence somewhere in the universe. Inside the bubble, the laws of physics are wildly different than they are outside the bubble. The bubble expands at the speed of light, eventually taking over the entire universe. Galaxies drift apart, atoms can’t hold themselves together, and the ways that particles interact are fundamentally changed. Whatever form the universe takes after this event certainly wouldn’t be hospitable for humans.

        And that’s the thing:

        Assuming it did, you couldn’t see it approach until it hit you because it’s moving at the speed of light! It could also have happened, but just super far away such that it will never reach us due to expansion between its origin point and us being faster than c!

        Also just because the universe is frickin old doesn’t mean it is statistically bound to have happened. There are plenty of ways of making it even more astronomically unlikely but still possible…

      Sounds like a great way to reboot the DC or Marvel universe. How probable is this bubble bursts and affects us before we fuck up our environment for good? Would we be able to know if it already happened somewhat far from us? Like, “we have 5 years, that’s all we’ve got”.

        Since the bubble travels at the speed of light, no, there’s no way to know. It could be an hour away from us right now and we wouldn’t even see it hit us, we’d just evaporate from existence nearly instantaneously.

        Has it not? Are you sure the bubble isn’t just 1 light second away? Anything travelling towards you at the speed of light is not perceptible until it hits you. This is why the ability to accelerate something to FTL speeds would be an unstoppable super weapon and most likely lead to interstellar species destroying one another until only 1 remains. Or at least that’s my take.

      Yeah, I can’t work up much existential dread at this prospect. Given the immensity of the universe, the odds of this happening anywhere that it will affect the human race anytime soon are pretty damn slim.

      Will there be infinite expansion or will the big bang eventually get reversed in to a big crunch? This question might not even be relevant if this bubble phenomenon rips the entire universe apart. What if such a bubble already exists beyond the horizon and will devour our galaxy in a billion years.

        We have no way to know what the resultant physics would be like within the bubble, so there is no way to even speculate about what would happen.

          Exciting times ahead. Who knows what will happen… if anything at all. It’s also entirely possible that nothing special is going on or ever will be.

    There are about the same number of bacteria cells in your body as human cells, and some of the bacteria in your intestines, ‘gut biome’, can affect your preferences for certain foods effectively controlling your mind.

    A ‘reference man’ (one who is 70 kilograms, 20–30 years old and 1.7 metres tall) contains on average about 30 trillion human cells and 39 trillion bacteria,

        Even when it is not deterministic at a single event, it is at a group of events. I know that sounds contradictory, and there is probably a better way to word that, but for example - if quantum randomness means that you cannot predict where a specific particle will go each time you measure it, you can predict the distribution curve of where the particle will be if you measure it some arbitrarily large number of times.
