What is the final outcome of mankind?

Ultimate torture

Compared with other creatures, humans are relatively unique. First of all, humans have self-awareness, which most animals do not have. Secondly, human language is far more advanced than that of other animals and can effectively cooperate in teams. Some scientists also believe that humans rely on this skill to become the overlord of the earth. Not only that, humans seem to be more intelligent and good at thinking. More than 2,000 years ago, many ancient civilizations had a lot of philosophical thinking. Ancient Greek philosophers began to think about the origin of all things, and Chinese philosophers also had similar thinking, which also established the cultural traditions of China and the West.

It can be said that being good at carrying out ultimate torture is also a major characteristic of human beings. Among many ultimate tortures, "What is the ultimate direction of mankind?" is often a hotly debated topic. It is precisely based on this kind of thinking that there are many calls to protect our home planet. To put it bluntly, many people believe that protecting our home planet can protect humans themselves.

Then the question is, for human beings, where is the final destination of human beings? The final destination of all things

Although humans are the overlords of the earth today, in the final analysis humans are still creatures on the earth. If divided according to the taxonomy of organisms, humans should belong to the animal kingdom - the class Mammalia. - Primates - Hominidae - Homo - Homo sapiens species.

To understand the final destination of human beings, we can actually first understand the final destination of other creatures. Life on earth originated 4 billion years ago. At that time, due to the extremely low oxygen content in the atmosphere, the sun's ultraviolet rays could directly irradiate the earth's surface. Ultraviolet rays were extremely harmful to life. Therefore, early life was actually born near the mouth of hydrothermal vents on the seafloor.

However, from 4 billion years ago to 500 million years ago, the form of life did not undergo particularly earth-shaking changes. Until 500 million years ago, the Cambrian biological explosion occurred on the earth. In just tens of millions of years, a large number of new species appeared on the earth. This sudden explosion of species cannot even be explained by Darwin's theory of evolution. It is still a big mystery in the biological world today.

It was during this era that different species began to dominate the earth, such as the earliest Anomalocaris and trilobites. They dominated for quite some time.

With the dramatic changes in the earth's environment, species are constantly changing. Sometimes it is a substantial increase or decrease in oxygen and carbon dioxide content, sometimes it is violent crustal movement, sometimes it is It's volcanic eruptions, sometimes violent temperature fluctuations, or even asteroids hitting the earth.

These changes have caused several mass extinctions and explosions of life on the earth. Now we know that there have been about five mass extinction events. The most recent one was the impact of an asteroid with a diameter of 10 kilometers. Caused by the Earth, during this extinction event, the dinosaurs eventually became extinct, and only a handful evolved into today's birds.

So even though it was as powerful as a dinosaur, it only dominated the earth for about 200 million years. Throughout the evolutionary history of organisms, all organisms cannot escape the word "extinction". This is actually what Darwin's theory of biological evolution tells us: natural selection, survival of the fittest.

The environmental conditions of the earth are constantly changing. Creatures that previously adapted to the environment will become extinct because they cannot adapt to the environment, and will be replaced by creatures that can better adapt to the environment. The final destination of human beings

Although humans are the overlords of the earth today, they possess "intelligence" and are better at adapting to the environment than other animals. But human beings are small compared to the entire earth, let alone compared to the solar system, the Milky Way, the local galaxy group and even the universe. Human beings may be able to survive the mass extinctions of organisms due to technological explosions. Humans can even travel interstellar to escape the end of the earth, the end of the solar system and even the end of the galaxy, but in the universe, we can never escape the end of the universe.

According to today’s scientific theories, we know that there are roughly five possibilities for the end of the universe: the big squeeze, the big rebound, the cycle hypothesis, the big tear and the heat death theory. These five possibilities can be divided into two categories, one is heat death and the other is cold death. In other words, if humans survive to the end of the universe, they will either die from heat or freeze to death.

If human beings fail to realize technological explosion and fail to escape from the earth and realize interstellar immigration. So, it would be difficult for humans to survive 500 million years on earth. This is because the earth's energy mainly comes from solar radiation, and the source of solar radiation is the controllable nuclear fusion reaction in the solar core. The sun relies on the balance between its own gravity and the outward pressure generated by the nuclear fusion reaction to achieve controllable nuclear fusion reactions. As the nuclear fusion reaction proceeds, the sun's own mass decreases, and the gravity also decreases. The sun controls the nuclear energy. The ability of the fusion reaction will also decrease, and the nuclear fusion reaction will become violent.

As a result, solar radiation will increase, and the temperature of the earth will rise. Scientists estimate that in 500 million years, the temperature of the earth will be so high that plants cannot survive. At this time, food The food chain based on photosynthesis will be destroyed, and humans rely on this food chain to survive. Therefore, humans will become extinct by that time because there is no food source.

Therefore, no matter how advanced human science and technology develops, human beings will never escape the fate of "extinction".
