open9 entries with the same name
Crop circle It refers to natural, astronomical, historical and other phenomena or events that can not be explained by existing scientific and technological means, or by normal thinking logic and reasoning methods[1]。The unsolved mysteries of the world can be divided into mystery of mysterious treasureUnsolved mysteries of mankindArchaeological mystery, historical and cultural mystery, alien visitor mystery, universe mystery, animal mystery, plant mystery, earth mystery, nature mystery.
When did life begin?What is the universe made of?Why do we need sleep?Science has developed by leaps and bounds, and we still have many difficult problems to solve.
one
What is the core of the earth?The center of the earth is 4000 miles away from the surface of the earth, where there is a solid iron ball the size of the moon.We all live on 1800 miles of rock, which forms the crust of the earth and the covering of the earth's surface.So,GeocentricWhat material is there between the earth's crust and the earth's crust?It's a pieceMagmaHowever, scientists are not sure what kind of material this piece of magma is composed of and how it will affect the surrounding environment.
two
Is time continuous?PlatoThink of time as continuous.andEinsteinThink that time is just another scale, except up and down, left and right, front and backFourth dimension。Einstein's concept of space and time works in theory, but it is difficult to do so in practice.Because we can only followtime axisWalk in one direction.In the end, someone will be able to draw the correct conclusion. It is just a matter of time.

Where does life come from?"Natural selection, survival of the fittest",Natural selection theoryIt explains how organisms evolved to adapt to changes in the environment.butDarwinBut it can't explain how the first organism came into being.Did compounds without any signs of life initially create life?firstLife formHow is it assembled?Nature didn't even give a hint.
four
What caused the Ice Age?Small scale ice ages occur every 20-40000 years, and large-scale ice ages occur every 100000 years.Scientists believe that,Earth orbitThe irregularity of the earth changes the amount of energy it absorbs, leading to the sudden cooling of the earth.But research shows that the irregularity of the earth's orbit only accounts for 1% of the impact on the earth's absorption of solar energy. How does this small impact cause a major change in the earth's climate?
five
Why decode DNA?A typical human cell contains 6 feet (1 foot is about 0.3 meters) of DNA, but only 1 inch (1 inch is about 2.54 centimeters) of DNA carries the code that needs to be used to make proteins. What are the other parts?Brenner, the Nobel Prize winner, found that they were waste products after research.But biologists believe that these so-called waste DNA also contains "wealth".
six
How do forests affect global warming?Everyone knows that forests help improve the environment.Trees will absorb carbon dioxide, the culprit of global warming, in the process of growth, but even so, the earth is still warming.Therefore, there is a contradiction that in the future, forests cannot slow down climate change, but with the continuous destruction of forests, global warming will become more severe.

How does the brain calculate movement?The brain is slow in processing the rules of movement. It takes several milliseconds to feel the heat when placing the hand on a hot plate. How can the brain obtain visual data at the same time in a short time, generate information that instructs the body to move, and calculate[4]How about setting a precise track so that the lizard's tongue can catch flies instantly, and our hands can quickly grasp the falling glass?

Why do the two poles of the earth transpose?About 800000 years ago, the compass would point to the south, and earlier, it would point to the north.Whenearth rotationIn the kernelLiquid metalStir together to produce an electromagnetic field.The change of movement direction of the core caused by rotation will change the two poles of the electromagnetic field.Once the process of heterotopia begins, it will take 7000 years for the earth to complete this major north-south reversal change.This will happen 2-3 times on average in a million years, but no one knows how it is realized.

Where has the black hole information gone?The attraction inside the black hole is very strong, and no matter or energy can escape the attraction of the black hole.But physicistsHawkingIt is said that something can escape the gravity of a black hole, which is“hawking radiation ”Such random particles.Ifblack holeIf the material with fixed structure can be eaten, then the black hole will be filled with all kinds of information and emit all kinds of uncertain noises. Where is the information?

Why can't we forecast the weather?MeteorologistLorenz In a computer weather simulation, it was decided to round off one of the parameters.This small change completely changed the weather model, which became famous later“Butterfly effect”。Lorenz's approach inspired meteorologists to input as accurate data as possible into computer models to expand theirForecast interval。However, extremely accurate data cannot enable us to obtain accurate long-term prediction results.Climatologists also need to understand the interaction between the atmosphere and the ocean and other factors that affect the weather.Therefore, it is basically impossible to predict the weather decades or centuries later.

Why is the disease prevalent?An epidemic disease is actually just the external manifestation of a pathogen "lucky".How bacteria infect depends on how they work and how resistant humans are.But no one knows how to predict when those bacteria will spread among people, so don't forget to wash your hands often.

Why can't our organs regenerate?Take a kitchen knife and cut it from your finger. This finger will always say goodbye to you.However, when a newt's leg is cut off, it will naturally grow a new leg.We will make a fuss about the damage to our nails, but the regeneration process of animal organs is so natural.Scientists want to know why the omnipotent human cannot do this.

Mathematicians can prove thatRiemannGuess?In the early 20th century, German mathematician Hilbert once said that if he woke up after 1000 years of deep sleep, the first question he would ask was: has the Riemann conjecture been proved?More than 100 years have passed, but there is still no answer to this question.The Riemannian conjecture will be distributed to zero on the basis of the so-called Riemannian zeta function.This conjecture has beenCray Institute of MathematicsAs one of the world's gold issues, those who can prove or falsify the conjecture will receive a bonus of $1 million.

Why do we die?When physicists are asked why things die, they will not hesitate to answer that this is consistent withThe second law of thermodynamics。Everything, whether it is minerals, animals and plants, or a car, will eventually disintegrate and die.This phenomenon in humans is to make people old.Aging may be caused by DNA damage or chromosomestelomereShrinkage occurs.If you want to know when life will end, you should also turn toecologist, but they only make a rough prediction and cannot accurately predict a person'sTime of death。

Where did human language come from?According to statistics, there are more than 7000 languages in the world.When and where did they originate?Are they of the same origin or independent origin?These are still unsolved scientific puzzles.In April 2011, a report of Science magazine in the United States caused great repercussions in the academic community.Quentin Atkinson, a New Zealand scholar, said in his report that human languages may all originate from the southwest of Africa, about 150000 years ago, when cave art began: they are of the same origin rather than independent origin.Since the 1990s, more and more linguists, archaeologists, psychologists, biologists, anthropologists and others have tried to use various new methods to explore the "world's most difficult academic problem" of language evolution.Unfortunately, due to the long history of human language, the complexity of language itself and the lack of strong scientific evidence, there has been little progress in the exploration of language evolution in the past 20 years, and there is no convincing explanation.Professor Zhou Haizhong, a well-known Chinese scholar, once pointed out that it is no less difficult to solve the problem of language evolution than to solve the mystery of species evolution;Language evolution is not only a social phenomenon, but also a natural phenomenon. It is also the result of human mental development and historical and cultural evolution;The origin and change of language has its internal causes and external influences, which increases the complexity of language evolution.[5]
