#人类会在宇宙中消失吗? #
Will humanity disappear from the universe? Judging from the current situation, the extinction of humanity is a high probability.
Because the birth of human beings is a matter of chance, and it is a matter of low probability. At least in the entire solar system, there is no life similar to human beings found outside the earth. Of course, in the solar system, the only planet that can be suitable for human life is the Earth - because Mars has no magnetic field, the Moon has no atmosphere, Pluto is too cold, and Venus is too hot. Even if humans could land on these planets in a matter of hours, they wouldn't be able to thrive on them.
What does the huge solar system mean that there is only one paradise for life on Earth?
It shows that the conditions for the production of life are very harsh.
And humanity is destined to face an even more serious existential crisis.
1. Imprison humanity
In fact, humanity is in captivity.
For human beings, the first shackle that imprisons human beings is the attribute of human life. For humans, life needs to be maintained at the right temperature, need to replenish heat, also need oxygen, and avoid the blow of cosmic rays. The Earth is the only planet in the entire solar system that meets the requirements of human beings.
This also means that although there are too many rocky planets in the solar system, it is impossible for humans to settle down. Because the condition of human beings is equivalent to human beings have been locked up on the earth. Of course, theoretically human beings can currently build workstations on the moon and continue to transport daily necessities to the moon to maintain the lives of lunar workers. However, this model is destined to be niche and difficult to sustain in the long term. If humans want to colonize the moon on a large scale, it is unrealistic. Therefore, the editor has thought more than once in his works that Musk's so-called immigration to Mars is a scam.
Of course, theoretically speaking, the universe is so big that there must be planets similar to the Earth. However, spatial distance has become the second shackle that imprisons humans. Let's assume that there is a planet 100 light-years away that looks exactly like Earth, and that humans can thrive on this planet as long as they migrate there. However, the distance of 1 light year is beyond human reach, let alone 100 light years.
You know, it only takes more than eight hours for sunlight to be launched from the sun to Pluto. However, it took more than a decade for human probes to get from Earth to Pluto. Therefore, the speed of walking for a month alone is an unattainable distance for humans, let alone 100 light years.
Thus humanity is imprisoned on Earth.
2. The end of mankind
In fact, the solar system has a lifespan.
Because when the sun reaches the late stage of the star, it will expand, and then the whole earth will be swallowed up: at first, the sun will put more heat energy on the earth, causing the earth's oceans to evaporate rapidly, and then the whole earth will become a sea of fire. Under the long-term scorching of the sun, the entire earth will also be burned to ashes.
Humanity does not possess the ability to resist this scourge, so it will disappear.
Of course, the Sun enters the old age of the stars, which is a very distant thing, and perhaps mankind will not wait for that day at all, and it will already be history.
