Why do people pay so much attention to the mystery of life in the universe?

Because people can think, and the more things they don't understand, the more they can't figure it out! This is human nature, otherwise people would not have evolved to be so smart. People are composed of a variety of elements, and after a certain permutation and combination, they can walk and think. It can also be inherited!

Maybe those researchers themselves can't figure out this problem, so it should be a kind of interest.

Yes, I also want to know how big the universe is, and if there is a four-dimensional space, can human life be extended indefinitely.

The article "The Mystery of Life in the Universe" mainly uses methods such as making comparisons, listing numbers, and giving examples.

For comparison: The author compares Mars with Earth and finds two similarities: the rotation time is similar; There are days and nights, there are four seasons, and it is cold at both poles.

Column numbers: In order to further confirm that there is no life on Mars, the author elaborates on the discovery of spacecraft, and uses the method of column numbers to prove that Mars has little moisture, thin atmosphere, low temperature, and no magnetic field, which shows that "life on Mars is difficult to survive".

Example: Through a field trip to Mars, the author cites two results: no organic molecules were detected in the soil, and plants could not grow without organic molecules; No microorganisms have been found, which means that there is no tiny life on Mars, which in turn negates the claim that there is life on Mars.

The central idea of "The Mystery of Life in the Universe" introduces the difficult process of scientists exploring whether there is life beyond the earth, and shows that to this day, whether there is life beyond the earth is still an unsolved mystery. It expresses the author's admiration for the scientists' spirit of pursuing true knowledge and continuous exploration, and at the same time stimulates students' interest in loving science, learning science, and exploring the mysteries of the universe.

Excerpt from the original text: Theoretically, the universe is infinite. The Earth is just the solar system.

and the solar system is just the Milky Way.

in a very small part. There are hundreds of billions of stars in the entire Milky Way, and there are quite a few planetary systems like the Solar System, among which there must be planets similar to Earth. It can be guessed that the Earth is by no means the only celestial body that has life.

However, humanity has yet to find another planet with life.

The Mystery of Life in the Universe is an expository essay, the full text is explained in the order of "asking the question, analyzing the problem, and drawing conclusions", and the paragraph structure is as follows:

Part 1 (1): It is written that the existence of life beyond the earth has always been an attractive question from ancient times to the present.

Part 2 (2-8): Begins with a general explanation of the theoretical assumption that the Earth is by no means the only celestial body with life, and then gives a detailed introduction to the process of scientists' exploration.

Part 3 (9-10): People have not yet found life beyond the earth, but they still believe in the existence of life and have been exploring the mystery of life in the universe.

The central topic of the mystery of life in the universe is "whether there is life in the universe except the earth", and the universe refers to matter and space-time, and the universe is a general term for the vast space and the various celestial bodies that exist in it, as well as the diffuse material slide.

The origin of the universe. is an extremely complex issue. Modern astronomical observations prove that it is in constant motion and the development of the letter mountain. For thousands of years, scientists.

We have been searching for when and how the universe was formed. Many scientists believe that the universe was formed by a large ** that occurred about 14 billion years ago.

According to the Spanish newspaper "Abesai" on December 16, the universe is a widely accepted theory about the origin of the universe. Loeb calculates that liquid water, a necessary condition for the existence of life, may have formed on rocky planets 15 million years later.

The mystery of life in the universe is profound, scientists are trying to explore this mysterious universe, scientists judge that Mercury, Venus, Jupiter, Saturn, Uranus, Neptune, etc. are unlikely to exist life, Mars may have life, but the probability is very small, the Milky Way is only the tip of the iceberg in the universe, scientists deduce that in this seemingly boundless universe, there must be more than the earth can have life.

The above content is not original.

Is there any other life in the universe? See what the scientists say!

There are 18 billion galaxies in the entire Milky Way.

Life in the universe is self-nurturing, because there is water, oxygen, and a suitable living environment, then it may cultivate new life. This is a necessary condition for the existence of life.

The universe is indeed an incomparably magical place, and the origin of life in the universe is currently inconclusive, and it is generally believed that life in the universe was conceived under specific conditions in the presence of water, air and sunlight.

The Mystery of Life in the Universe uses a column of numbers (useful in paragraphs 3, 4, 5, and 7) to give examples (useful in 2 paragraphs) and comparisons (useful in paragraph 5).
