The world may be beautiful, but dig deeper and you'll find hidden horrors. From the crises of the natural world to the intricacies of human relationships, there is a fear of the unknown in everyone's heart. Today we have screened out 30 of the most chilling truths that reveal the most terrible truths in people's eyes, and let's bravely uncover these little-known truths and explore the other side of this world.
1. The Earth existed billions of years before us humans, and it was indifferent to our state of existence. There have been many mass extinctions in history, so we shouldn't feel safe. The only change is that we have evolved to the point where we can predict the extinction of species, including our own, in advance.
2. The Permian extinction was the worst mass extinction in history, when the atmosphere was filled with carbon dioxide, the oceans were warm, and oxygen levels were so low that most organisms could not survive. And now, we are recreating these catastrophic events through climate change.
3. The permafrost of Siberia is melting, unleashing diseases that humanity is not yet ready to deal with.
4. Either we are the only beings in the universe who have the ability to sentient, or we are not. In either case, it's just as frightening.
5. The U.S. military has lost several nuclear weapons, all of which have not yet been recovered.
6. Since 2010, we have recorded the hottest decade in history. Not only will we experience catastrophic temperature rises of 2 degrees this century, but they may even be higher. And most desperately, even if we achieve net-zero emissions by 2070, temperatures could still rise by 2 degrees. The window of time to prevent a disaster closed some 20 years ago — and we are now living in an era of disaster management.
7. There are people who traffic in human beings and then return to their families in peace and to live comfortably in a better place than many of us.
8. Advanced scurvy can cause all the scars to re-dehisce because maintaining the scar is an ongoing process in the body that stops when the body is unable to produce collagen.
9. One of the truly frightening facts is the existence of "antibiotic resistance". Bacteria have evolved resistance to the antibiotics that we use to treat bacterial infections. Overuse and misuse of antibiotics can accelerate this process, making it difficult or even impossible to cure otherwise treatable conditions. According to the World Health Organization, antibiotic resistance is one of the biggest threats to global health today and could cause some simple infections to become fatal again in the future.
10. From a physiological point of view, constipation can be so severe that it can cause stool to flow back into the digestive tract and may even vomit stool. You are welcome.
11. A truly frightening fact is that the number of bacteria in and on our body actually exceeds the number of cells in our body.
12. Sleeping less than 7 or 8 hours a night can be far more harmful to the body than people think. It significantly increases the risk of everything from obesity to Alzheimer's disease to heart disease and impairs essentially all brain functions. Also, the brain isn't physiologically fully aware of the level of sleep deprivation, so if you're the type of person who only gets 4 or 5 hours of sleep a night, then you may not realize that you're actually not getting enough sleep.
13. We need to work for 11 months in exchange for one month off for the whole year. Most people need to work in similar jobs until retirement and then rely on a meager pension to make ends meet.
14. Creutzfeldt-Jakob disease (BSD), which can have an incubation period of more than 50 years, is a disease that is often fatal and hereditary. There is currently no effective treatment.
15. Brain aneurysms are usually asymptomatic but can lead to death if ruptured.
16. You may have contracted rabies by now, but you won't know until the symptoms start to appear. However, by then it was already too late.
17. In the United States, there are hundreds of unidentified serial killers.
18. There is a caterpillar that is believed to be native to the United Kingdom and is capable of tricking ants into believing it to be a troubled queen. The ants will bring this caterpillar back to the nest, while the caterpillar will continue to act like a queen but will devour all the ant larvae, thus destroying the colony from the inside. Some studies have shown that this species is even able to actively seek out those larvae that will eventually become the next generation of queens and devour them first.
19. Some spiders feed on snakes.
20. Some scientists believe that flies are the most dangerous of all animals because they are highly susceptible to spreading diseases.
21. Blue whales weigh up to 500,000 pounds, and they are able to communicate thousands of miles away.
22. It's a Beautiful Day. You go swimming, but Naegleri fowleri strikes you hard. Negleria flexneri is an amoeba (also known as a brain-eating amoeba) that can cause severe central nervous system infections. This amoeba is found in a warm, freshwater environment and enters the human body through the nose.
23. There have been historical incidents in which solar eruptions have caused power outages on several continents. In the 19th century, such an eruption may have been just games and entertainment. Today, however, it could easily lead to millions of deaths. Such an event can happen at any time.
24. About 130 light-years away there is a white dwarf star that could explode at any moment. If it exploded, it would be a giant cosmic firework – and so close to us that it could raise a series of questions. Even if it turns into a neutron star without exploding, such a phenomenon could have a nasty electromagnetic pulse effect that could destroy many moons.
25. Some planets fly freely in space without orbiting any star. If such a planet crosses our solar system, it could easily push the Earth out of its orbit, causing us to be blown up or frozen and there is nothing we can do about it.
26. If we can't find the best way to travel through space, we will become extinct.
27. There Is A Chance Of At Least One Murder In Your Life.
28. There is no age limit for dementia.
29. Humanity is the greatest threat to our own extinction.
30. According to statistics, 50-70% of people do not have an inner monologue. I can't even imagine this situation because I can barely stop my inner monologue and go to sleep. Although opinions in the comment section are divided, many people say they have not experienced an inner monologue. I see this as a form of monologue. I think some people might be confusing it with conversation, but maybe some people really have that experience?
