What is the movie called when text messages show life time?

Jiutian Lingshe will answer your questions:

There are several questions that people will definitely think about when they are alive, such as "What is the universe? How big is it?", "How is the world?" "Who am I? Who are you? Why are you and me?" and other seemingly boring questions that everyone has thought about but cannot figure out. Different people from ancient times to the present have given different models. There is God creating the world, there is Allah creating the world, there is Brahma dreaming the world, there is everything is empty, there is everything is nothing, no matter what kind of religion it is

< p>The questions surrounding this question of why it comes into existence and why it dies are so difficult to understand and so mysterious. In this article "I" put forward my own point of view to explain this issue, and hope to discuss it with every friend who is thinking about these issues.

Among the nine planets in the solar system, the light blue Earth is the only one full of life. In its mountains, oceans, forests, blue skies, and poles, there are nearly two million active planets. kind of life, it is well-deserved

The paradise of life. But why does life love the earth so much?

Although the academic community is currently unable to accurately define life, life is a complex phenomenon that has two basic characteristics: first, the ability to reproduce itself; second, the ability to metabolize. Both activities require energy. As far as animals and plants are concerned, the ultimate source of energy is the sun.

If a planet is too far away from the sun, such as Pluto, it receives very little sunlight and is like the legendary underworld, where life cannot survive because it does not receive enough energy; if a planet is too close to the sun, , such as Venus

The star receives a lot of sunlight, and the temperature during the day and night is above 400 degrees Celsius. It is like the mythical purgatory, and life is difficult to survive.

The earth is neither too close nor too far from the sun, and receives moderate light. Plants can freely use solar energy to perform photosynthesis and store the energy needed for life activities. When vegetarian animals eat plants When the carnivore eats the vegetarian animal, the stored energy enters the body of the vegetarian animal. When the carnivore eats the vegetarian animal, the energy enters the carnivore's body again... In this way, it is the light energy of the sun that drives the animals on the earth. And the life machine of plants, so that the descendants of animals and plants can flourish and live endlessly.

Suitable temperature on the earth is necessary for life activities. The energy required for life activities is supplied through metabolism, and an environment that is too cold or too hot is not conducive to normal metabolism. Only at a suitable temperature can plants effectively carry out photosynthesis.

The earth is protected by an atmosphere, which is by no means dispensable for the life living on it, because: the atmosphere blocks the strong ultraviolet rays from space, making life on the earth immune to The atmosphere has blocked most of the meteorites that hit the earth, so the earth's surface is not as bumpy as the moon's surface; the atmosphere is like a thick quilt, preventing the sun from hitting the earth's surface. Light will not be emitted into space, and the temperature on the earth will not change drastically. Without the protection of the atmosphere, there would be no wind or rain on the earth, and there would be no rivers, lakes or seas. , the earth will be a dead and desolate planet.

There is prosperous life on the earth, which cannot be completely separated from the fact that it is a rocky planet. The core of the earth is molten magma, and the main component of magma is iron. As the Earth rotates, its iron core generates a strong magnetic field.

This magnetic field surrounds and protects the earth. When solar storms, which are high-speed streams of charged particles from the sun, hit the earth violently, the magnetic field surrounding the earth blocks it in space, thus protecting life on earth

.

For life, the conditions on the earth are unique.

However, in the vast universe, the solar system is just a small part of the ocean. The sun is not the only star in the vast space. Is the earth the only planet inhabited by life in the vast sea of ??stars?

The original water environment of the earth gave rise to conscious objects on the earth. After a long period of evolution and some environmental factors, aquatic creatures began to live on land. Even in the heyday of the dinosaurs, due to the impact of asteroids, The extinction of most species (the explanation with the highest support rate at present) is about 99%, which gives some innately weak creatures a chance to develop. After a long time, apes evolved and gained some wisdom. The accumulation of years has led to the current knowledge. The long history, and the humans who now temporarily dominate the earth.
