22 amazing scientific truths, worldview has changed...

In other words, all groundbreaking discoveries in history of science are counterintuitive, most famous of which is double-slit interference experiment. However, in fact, there are many such examples that refresh people's understanding of real world...

Recently on Reddit, netizens asked: What scientific facts surprised you? Many netizens have provided their own answers, some of which really ruined world view... Let's experience it together:

1. Squids have one of strangest brains in animal kingdom. Not only does it look a lot like a donut, but esophagus runs down middle... so they have to grind the food into small pieces and eat it. If too much, it will really cause brain damage...

2. Dinosaurs, from point of view of cosmos, must have lived on other side of galaxy... Since our Sun revolves around center of galaxy when Earth was on other side of galaxy, many dinosaurs still roamed earth.

So, if you have ability to travel to past, but you're not earthbound, 99.999% of them will go into space... and remaining 0.001% will probably be inside earth...

3. Botanically speaking, broccoli, cauliflower, cabbage, kohlrabi, etc. are all same plant: cabbage.

It's just that in last few thousand years, a certain part of characteristics stood out especially when grown by humans (buds, leaves, tubers ...), in general, plant genetics is a strange world.

4. The Moon is closest planet to Earth, distance between which is about 380,000 km.

However, in such a space that seems very close, you can actually pack other 7 planets in solar system... even adding Pluto is not a problem!

5. About 99.85% of mass of solar system is concentrated on Sun, and eight planets contain only about 0.135% of mass of solar system

In other words, mass of our solar system, including Sun, Jupiter, and rounding error...

6. Why do shoelaces always loosen easily on their own? Because they carry more power than a roller coaster...

According to a study, when a person is running, accelerometer measures up to 7 G's on shoelaces, while world's most powerful roller coaster, Tower of Terror in Johannesburg, South Africa, experiences an overload. only 6.3 GB...

7. Voyager 1 was discovered at a speed of 50,000 km/h, flew in space for 43 years and became first man-made object to leave solar system in 2017.

However, it is only 20 light-hours away. At this speed, it would take about 80,000 years to reach nearest star, Alpha Centauri, which is world of three bodies in novel Three-Body Trouble...

Some people have calculated that if you are a travel driver, you will earn one dollar for every kilometer you drive. At this speed, you will have to fly for almost 400 years before you can become richer than Bezos, richest man in world today...

8. When you sleep, one part of your brain makes up story of what happened in dream, and other part of your brain is a witness to this story and is shocked by twists and turns of plot!

It is true that I wrote, filmed and acted myself and watched it with pleasure.

9. For most of time that dinosaurs existed, there were dinosaur fossils on this earth...because span of time that dinosaurs ruled earth is too long! (160 million years)

It's also similar: compared to Stegosaurus, Tyrannosaurus Rex is actually closer to iPad on time axis... 90 million years before birth of Tyrannosaurus Rex, Stegosaurus rex died out, and Tyrannosaurus Rex died out 6500 years ago. back.

10. If you put all animals on ground in 1 bag and choose one from it, you have 1/5 chance to choose a bug and 1/2 chance to choose an insect.

In other words, half of all animal species are insects and 40% are beetles. If there is a Creator, he must have had an excessive love for stars and beetles.

13. The number of atoms in a teaspoon of water (about 5 ml), approximately 2×10^23 water molecules, 6×10^23 atoms...

No concept, right? As they say, sea water cannot be measured, but if you take water with this teaspoon, 6 × 10 ^ 23 times you can scoop up Atlantic Ocean 8 times ...

14. How small is an atom? I believe that many people do not have specific concepts, at this time only through comparison can one feel how small it is! If an atom is size of a grain of dust, then a grain of dust is size of Earth...

15.Siblicid, cannibalistic behavior between baby animals, some animals will give birth to several offspring at same time, but in fact most of them are just as a fallback in case firstborn does not survive... < /p>

Remember watching a mantis egg hatch in high school science class. A classmate asked teacher, "What food is small enough for them to eat?" He just casually said, "They themselves are food."

In addition, Sibicide can also appear as twins in womb of a human mother...

16. When anglerfish mates, male parasitizes female's body, becomes part of female's body and integrates with her...

Hydrogen is called mother of elements, and all other elements are converted from hydrogen, so put a bunch of hydrogen gas in there long enough and it can do anything...

22. Every atom in your body came from an exploding star. The atoms that make up your left hand may come from other stars than atoms that make up your right hand. This is truly most poetic thing I know from a physicist: we are all stardust... so forget about Jesus, stars have died so you can be here today. ——The journey of an atom through time and space, physicist Lawrence Krauss

The universe is very big...
