In other words, the seminal discoveries in the history of science are counterintuitive, the most famous of which is the double-slit interference experiment, however, there are many examples like this that refresh people's understanding of the real world.
Recently, on the reddit website, a netizen asked: What are the scientific facts that surprise you? Many netizens contributed their own answers, some of which really made people's worldview collapse... Let's take a look:
1. The squid has one of the most peculiar brains in the animal kingdom, not only does it look very much like a donut, but the esophagus also passes through the middle... So they have to grind food into small pieces when they eat, and if they eat too much, it will really cause brain damage...
2. Dinosaurs, spatially speaking, should have lived on the other side of the Milky Way... Because our sun orbits the center of the Milky Way, many dinosaurs roamed the earth when it was on the other side of the galaxy.
So, if you have the ability to travel to the past, but you are not bound to Earth, 99.999% will go into space... And the remaining 0.001%, will probably be in the earth's interior...
3. Botanically speaking, broccoli, cauliflower, cabbage, kohlrabi, etc., are actually the same plant: kale.
However, in the past few thousand years, under the cultivation of humans, a certain part of the characteristics are particularly prominent (buds, leaves, tubers..... Overall, plant genetics is a strange world.
4. The Moon is the closest planet to our Earth, and the distance between the two is about 380,000 kilometers.
However, in such a seemingly close space, in fact, the other 7 planets of the solar system can be crammed into it... Even adding Pluto to it is no problem!
5. Solar system, about 99.85% of the mass is concentrated in the sun, the eight planets contain only about 0.135% of the mass of the solar system
In other words, the mass of our solar system, which includes the Sun, Jupiter, and a rounding error...
6. Why are shoelaces always easy to loosen on their own? Because they carry more power than a roller coaster...
According to the researchers' tests, when people run, the overload of shoelaces is measured by accelerometers as high as 7 G, and the world's most powerful roller coaster, the Tower of Terror in Johannesburg, South Africa, has only 6.3 G...
The Voyager 1 probe, which has been flying in space for 43 years at a speed of 50,000 km/h, became the first man-made object to leave the solar system in 2017.
However, it is only 20 light hours away from us, and it takes about 80,000 years to fly at this speed to the nearest Centauri α star, the three-body world in the novel Three-Body...
Some people calculate that if you are a driver of travelers, you have a dollar for every 1 kilometer you travel, and at this speed, it will take about 400 years to fly for almost 400 years to be richer than Bezos, the richest man in the world today...
8. When you are dreaming, one part of your brain makes up the story that happens in the dream, while the other part witnesses the story and is shocked by the twists and turns of the plot!
I really did my own writing and self-directing, and I also watched it with relish, which is really scary to think about...
9. For most of the time of the existence of dinosaurs, there were already dinosaur fossils on this earth... Because the time span of dinosaurs ruling the earth is too long! (160 million years)
Similarly, compared to Stegosaurus, the Tyrannosaurus Rex is actually closer to the iPad in the timeline... Stegosaurus rex was extinct 90 million years before the birth of T. rex, and T. rex was extinct 6500 years ago.
10. If you put all the animals on earth in 1 bag and pick one out of it, you have a 1/5 chance of picking out the beetles and a 1/2 chance of picking out the insects.
In other words: half of all animal species are insects, and 40% of them are beetles. If there really is a Creator, then he must have an excessive fondness for stars and beetles.
11. Have you ever wondered where all the fat you lost went? Some people would say that fat can be dissolved, burned, broken, broken, left the body in a poop manner, and so on
In fact, 84% of fat is excreted with breathing, just exhale a few more breaths... Keep in mind that fat has and only one way to leave your body:
12. There will be no cockroaches in the methamphetamine laboratory, because the manufacturing process of methamphetamine produces toxic gases such as phosphine, a common insecticide that is usually used in silos to deal with pests.
So in the American drama "Breaking Bad", Lao Bai will think of pretending to be an insecticidal company to make poison, which is not unreasonable...
13. The number of atoms in a teaspoon of water (about 5 mL), about 2× 10^23 water molecules, 6× 10^23 atoms...
There is no concept is it, as the saying goes, the sea is incomparable, but if you use this teaspoon to fetch water, 6× 10^23 times can scoop the Atlantic Ocean 8 times...
14. How small are atoms? I believe that many people do not have any specific concept, at this time only through comparison can you feel how small it is! If an atom is the size of a grain of dust, then a grain of dust is about the size of the Earth...
15. Siblicid, the act of cannibalism between animal cubs, some animals will have multiple offspring at the same time, but in fact most of them are only used as a backup, in case the first born can not survive...
I remember witnessing a mantis egg hatching in high school science class. A classmate asked the teacher, "What food is small enough for them to eat?" He just casually said, "They are the food themselves." ”
Alternatively, Siblicide can also appear in the womb of a human mother in the form of twins ...
16. When the anglerfish mates, the male will parasitize the female's body, become part of the female's body, and merge with it...
This mating method is also known as "sexual symbiosis", in which the male's organs disappear and atrophy and become the testicles that the female uses to fertilize the eggs... Sometimes this, sometimes on a female fish, there is more than one such pendant...
17. The speed at which time passes is not a constant, it is not immutable for all things, and the stronger the gravity and the faster it is, the slower time will be...
Therefore, the time of GPS satellites in the sky and the ground is actually different, and the time expansion effect of their software must be corrected to correct the ground station.
18. So traveling through time is not, the former Soviet cosmonaut Sergei Krikalev, has been called "the most prolific time traveler in human history"...
He spent a total of 803 days, 9 hours and 39 minutes in space, and after returning to Earth, he actually traveled to the future 0.02 seconds later...
19. Some fish eggs can actually survive after being eaten by waterfowl, and will be excreted with bird feces and hatched. Although the success rate is small, it is also a way for fish to migrate and invade, which may explain why some isolated puddles in remote places can always appear out of thin air, dig a puddle at will, and fish will appear over time.
20. Caterpillars, before turning into butterflies, melt mucus almost completely in their cocoons... Their bodies dissolve into cell plasma, which then differentiate into the various organs of the butterfly...
However, after going through this process of "reincarnation", the butterfly can still retain the memories of the previous caterpillar period...
21. The British cosmologist Edward Harrison once said: "Hydrogen is a colorless and odorless gas, and if you give it enough time, it will become a human being." ”
Hydrogen is called the mother of the elements, and all other elements are converted from hydrogen, so if you put a bunch of hydrogen for a long time, it may do anything...
22. Every atom in your body comes from an exploding star. The atoms that form your left hand and the atoms that form your right hand may come from different stars. This is really the most poetic thing I know of physicists: we are all stardust... So forget Jesus, the stars are dead and you're here today. —"An Atom's Journey through Time" physicist Lawrence Klaus
The universe, very grand...
Life, greater...
