If there was no sun, how would the earth have changed from its origins to its development

Press"Nebula said"The sun and the earth evolved from the same nebula, the nebula evolved into the sun at the beginning, and the remaining nebulae evolved into nine planets, at the beginning the earth did not have any life, if there was no sun, there was no ultraviolet rays, and the most basic bacterial life could not be constructed, green plants could not photosynthesize, release oxygen, and life could not live.

The Earth will fly out of the Milky Way and become a comet.

Even the Earth itself will not be formed, because the Earth is separated from the Sun.

You got the logic wrong, the sun is like the mother of the earth, what do you say will happen without a mother and a son?

The mother doesn't have a son?

The earth is the solar system, and if the sun is not Luo, the solar system will not exist, and the earth will not be there There will be no such thing as your answer on the Internet

yo!!1yo!! check it out!!Why do you ask this kind of question? Without the sun, there would be no father-in-law, mother-in-law, father, and mother, and even more without your father-in-law, and your ancestors

If there were no sun, the earth would not have been formed.

If there were no sun, there would be no earth, and there would be no human beings.

Without the sun, the earth would not have formed at all, where did it come from, and what origin and development. Not to mention people.

What I think is a philosophical question is here to show off?

All of the above is true, there is no earth without the sun.

If there was no sun, there would be no earth, and without earth there would be no human beings.

1. If there were no sun, there would be no plants on the earth, and there would be no animals.

2. With the sun, there are clouds, rain and snow.

3. Only when there is the sun can there be wind.

4. Sunlight has the ability to sterilize.

5. Without the sun, there would be no beautiful world of ours.

This is a short popular science article, the article uses the method of listing numbers, analogies and other explanations, introducing some knowledge related to the sun, showing that the sun and human beings have a very close relationship. The purpose of this lesson is to enable students to increase their knowledge of nature in the text, learn to look at the natural world from a relational perspective, and stimulate their interest in learning natural science. At the same time, you will be exposed to the methods of explaining things, and you will learn to read explanatory texts.

What marks the official birth of the solar system? This question solves your question. You might as well give two criteria, as follows:

1. If the solar system is formally formed by the fact that the sun enters the main-sequence stage (i.e., the internal hydrogen fusion begins to occur), then it can be considered that the earth was born at the same time as the solar system, because at this time the mass of the sun was already quite large, larger than it is now, and the powerful density wave on the eve of the fusion "ignition" has turned the original accretion disk into a system of orbital objects, and the planetary billet has been formed, not a structure like Saturn's rings.

2. If the solar system is formally formed by the state of the sun becoming a protostar, then the formation of the earth will be later than the formation of the solar system, because the material that made up the earth during this period is still a part of the accretion disk of the entire protostellar disk of the sun, or scattered cosmic detritus.

It is recommended to refer to the Taurus T-type star.

In about 5 billion years, our Sun will enter the end of its evolution and become a red giant. Its inner core will gradually shrink to become a white dwarf, while its outer shell will expand rapidly, reaching a diameter of almost 200 million kilometers.

The Sun will enter the red giant to white dwarf phase:

The planets that once orbited the sun have been ruthlessly torn apart and devoured by it. It is speculated that these planets should have fallen into white dwarfs after their previous stars expanded into red giants and ejected their shells completely into space. When the Sun enters the end of its evolution, entering the red giant or white dwarf phase, the four rocky planets on the inner side will face a life and death test.

The sun may end up swallowing the Earth:

The distance between the Earth and the Sun is about 100 million kilometers, and the Earth's orbit will definitely be swallowed by the Sun. As a result, the planet is likely to face an unprecedented crisis. If the earth had remained in this position, then it would have been swallowed up by the sun and reduced to ashes.

Of course, scientists also have a relatively optimistic expectation that the strong solar wind will push the Earth farther away, saving the Earth from being swallowed up. <>
