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,

That probably freaks me out just as much as time passing not being fundamental under B time indicated by general relativity or free will being illusory and the universe is more likely deterministic.
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.
Here's a good video on it.
That explains my life.
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
Can we just aim it at Belgium and all have a jolly good laugh?
Well, I guess it is racist Wednesday for some of the planet currently, even if not my timezone ....but why them?
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.
So spontaneous instant death. Not scarier than an aneurysm.
This is know as "False Vacuum (Decay)". Kurzgesagt made a video about it.
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 somewhere far from us? Like, "we have 5 years, that's all we've got".
It’s that effing Peter Parker again. No matter how good the wizard, you can’t keep interrupting while he is trying to change memories across the entire multiverse
Cop knelt and kissed the feet of a priest and a queer threw up at the sight of that
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.
Really looking forward to the Spacetime episode on this one if it doesn't exist yet.
As old and massive as the universe is, if it could have happened, it likely would have already.
Basically, as big and old as the universe is, it's easy to pick an even bigger number for the expected recurrence of a vacuum decay. So, it's still possible.
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...
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.
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.
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.
SOURCE: I'm old and outside a lot. Always looking around, seeing what's changing.
If you think about it, when was the last time you saw a lighting bug. I've never seen a firefly in my entire life despite living in a country that had native species.
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
I have seen them twice in the last year, but it was only a single bug each time. A sad lightning bug trying to find others to mate... I didn't see another one around it.
As a kid, I would see hundreds of them around bushes and trees. Now I see one or two per summer.
But that’s all gods plan, right?
In new hampshire, relatively often when it's the right season.
Thankfully they are alive and doing quite well in our little forest home in Quebec, Canada. Of all the places I used to see them as a kid almost none are still vibrant and busy, but our little corner of forest here has a good population. For now...
Hell no I Wana see that ... People finally taking serious actions against it when its way too late ... There's nothing better then seeing rich people trying to buy stuff that can't be bought... And finally dying full of regrets knowing it was their and theyr families fault.
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
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.
"Lethal amounts of diarrhea" has now entered second place on my Worst Nightmares list. Thanks for that...
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 time at 100C. (To can vulnerable things properly, you use high pressures to make the water get hotter before it begins to boil, and cools down as a result)
Viruses are sneaky! Their whole goal is to trick you into helping them survive and reproduce.
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.
they are then pooped out onto other snails? How does this life cycle work
That's rough, oof!
Read the Wikipedia article on Radon. That should do the trick.
There's worse. Ever heared of FOOF? https://www.science.org/content/blog-post/things-i-won-t-work-dioxygen-difluoride
Aww but it sounds so fluffy
Eh, FOOF is so unstable that it's very hard to make enough of it to do any real damage. It's also just very hard to make. It's only remotely stable at cryogenic temperatures, and is so reactive that without an inert atmosphere it will rapidly decay into something more stable. Granted, it will do so by oxidizing the molecular oxygen in the air (which is as insane as it sounds) and release a ton of energy in the process but assuming you don't already have a bunch of it, you won't be able to create enough of it fast enough to do any meaningful damage without a specialized laboratory and associated equipment.
Chlorine Triflouride however, can be made in your kitchen, and is just stable enough that, assuming you've taken some precautions, it's possible to accumulate enough of it to immolate yourself in one of the worst possible ways.
I’m only just barely smart enough to occasionally realize that when the smart people start quietly losing their shit over something I can’t possibly understand, I should have long since been gone by the time they start losing their shit over whatever magic has now prematurely doomed the universe to its inevitable heat death.
Or I could just drink my face off. That works, too.
OMG explosions and fire just did an episode on this. He went to a lab in Germany and they made some...
Release 9 days ago.
When I was a kid my parents wanted to open up an existing cavity under our house to build a basement, and that never happened because it (E: was discovered during the building inspection that it) was full of Radon. I guess I'm desensitised (but possibly slowly decaying a little faster than I should be..).
