In life, people can always think of some strange questions, such as will the earth fall? Now, we are focusing on this issue. Can pi be calculated? If it is calculated, what consequences will occur?

Now, we will focus on this issue. Can pi be calculated all ? If you have done everything, what will happen?

irrational number ? rational number ?

We have always considered pi, that is, π, to be an irrational number. It has the characteristic of infinitely not looping , so there is no saying that it is calculated.

But is it really scientific just because it has not reached the end and it is really reduced to irrational numbers? Maybe it really has no end, maybe its end is beyond human computing power.

After all, for the entire universe, it is so big that it is scary to measure by numbers.

For example, The observable universe has a diameter of about 96 billion light years, which is equivalent to 960 times 10^8 light years, which is equivalent to 960*10^8*10^12 kilometers.

observable universe concept

believes that compared with the entire universe, this value is just a speck of dust in the desert.

So, is there such a possibility: Pi is actually has an end to , but people just don’t count it there?

In 2019, Google publicly announced that it has calculated pi to 31.4 trillion digits after the decimal point.

In 2022, Google once again broke its own record and calculated that it was 100 trillion digits after the decimal point.

At this time, someone may ask, is 100 trillion not enough? You should know that this number can already be included in the ranks of astronomical numbers, but this is still too "small" for the entire universe.

The vast universe

Perhaps, after humans calculate pi to tens of millions of trillions of in the future, they can draw conclusions from practice.

However, as early as the mid-last century, the famous mathematician Ivan Niven used calculus and inverse proof method to theoretically prove that pi is an irrational number.

The whole process is a relatively brain-burning equation, so I won’t give you an example.

However, theory is a theory after all. Since ancient times, countless theories have been overturned. Chairman Mao said, " practice is the only criterion for testing truth."

Although we have no way to prove from practice whether it is an irrational number, we can imagine what will happen if the pi is calculated?

π

Pi is calculated

Although pi is just a "small" number, it is one of the most core existences in the entire mathematics community .

In order to ensure the accuracy of the building, engineers usually take pi decimal point 0 digits after calculating.

In the aerospace field, the pi is accurate to 40 digits after the decimal point, or even more.

Therefore, if pi has an end, all the projects people built have defects, and a series of aerospace equipment such as rockets will not operate properly.

calculus with pi as the core will also not be valid. The mathematical community will cause an uproar, and all theories and equations about pi must be re-established.

This is undoubtedly cruel to humans. After all, all the accumulation in the mathematics community today is the essence left over from all generations. If it is overturned all at once, many mathematicians may go crazy.

In addition, many physics formulas require pi, of course, the premise is that pi is an irrational number.

For example, Einstein 's gravitational equation puts pi in an important position.

Einstein's gravitational equation

If the pi can be calculated, the current universe and space-time may be beyond people's imagination, and the particles of microscopic world are not what the scientific community observes.

Pi is also used in password . Some important information will be encrypted and information can only be extracted through a specific key.

key is equivalent to the password lock of the safe. Previously, when people set up keys, they usually extracted random numbers on the computer as keys.

However, powerful computer hackers can track the "random" process of the computer to steal keys.

Later, people took advantage of the infinite pi and no looping feature, and used its numerical values to form a real random number. No matter how powerful the computer hacker is, it is impossible to steal the key.

Computer hacker

If there are limited pi, no matter how many digits there are behind it, as long as the computer performance meets the standards, hackers can steal the key. It is only a matter of time.

There are rumors that the US and Russia's nuclear weapon control system uses this key to ensure the absolute security of the system.

Nuclear fusion and nuclear fission

0 Pi is limited, which means that humans have to find new security keys. Before this, if it was deciphered by some people with ulterior motives, the world would be in crisis.

Optimistically, if the pi is calculated, it will also be beneficial.

Some scientists speculate that pi may be related to the size of universe . Since the universe has been expanding at super-light speed, and human calculation speed is limited, so it is impossible to calculate pi to the end, nor can it be discovered the boundaries of the universe.

The universe has been expanding rapidly

The end of Pi is the mystery of the universe.

And, something that cannot be explained by science may also be solved by the end of pi.

For example, our magical quantum mechanics is called the closest existence to theology.

Because the world of quantum is very unique, all phenomena exceed people's cognition.

The famous Schrödinger's cat experiment proposed that in the quantum world, cats are in the superposition state of life and death .

and quantum entanglement are even more difficult to understand. Simply put, if two particles are in an entangled state, their direction of change is the same, and this change can ignore the distance.

Quantum Entanglement Concept Diagram

If one of the particles flips around, the other will be inverted even if it is 10 billion light years away, will also be inverted at the same time .

Many people believe that Einstein's general relativity was broken, because the general relativity theory pointed out that information cannot super-light speed .

For example, the person at point a and the person at point b are 3 light years apart. Point a wants to say Happy birthday to the person at point b. No matter what method is used, the person at point b will take at least 3 years to receive the message.

Therefore, the supernova explosion that we have observed now is likely to have happened thousands of years ago, and now we have only passed the information here.

The ending of supernova explosion

Strangely, two examples in the state of quantum entanglement can actually ignore the speed of information transmission. What's going on?

At present, scientists can only attribute it to the wonder of the quantum world, and Einstein's general theory of relativity is no problem.

So, what is the relationship between pi and the quantum world?

If pi can be calculated, it can provide people with a new idea to study the quantum world, prompting us to uncover the mysterious quantum world.

magic number

In addition to pi, there are many magic numbers in the mathematics community.

First, 8020, in layman's terms, in the development of social things, the important part can only account for 20%, and the unimportant part can account for 80%.

8020 concept

This is one of the laws for social to run stably. For example, most of the wealth of human beings is in the hands of these 2 adults, while the remaining 8 adults have little impact on the entire society.

For example, in an industry, real elites only account for 20%. They are industry decision makers, which determine the life and death of the industry. The remaining 80% are workers, and the impact on the industry is not that great.

Pyramid number 142578, it is said that this is the number left in the pyramid, which can prove that there are 7 days in a week.

If you separate the string of numbers from and add them, you can get 999, and the more you divide one bit, there will be one more 9.

shows how wonderful the world of mathematics is.
