There are many dangers hidden in the universe, is it the sun that has been protecting us?

At present, the mainstream scientific community believes that the universe came from a major catastrophe, and the margins of the universe began to expand rapidly, and many celestial bodies were produced at the same time. When the celestial bodies were first born, they were still moving at high speeds, and there were no laws to speak of. So at that time, some big ** could often be seen in the universe.

The main reason was that the celestial bodies were moving too fast at that time, and because they had not yet formed a balance with each other. This caused a lot of celestial bodies at that time, and many small fragments were formed in the **, floating farther into the universe. <>

In a stable galaxy, stars usually form first, mainly because they need to swallow a large amount of celestial matter around them in the process of formation. Only in this way can it complete its own accumulation, form a high-temperature and high-pressure internal environment, and thus ignite itself to complete the final step of nuclear fusion. It is also possible to become the smallest galaxy system only if stars are formed first.

The smallest galaxies in the universe are galaxies. <>

Why does the sun protect us all the time? The main reason is that after the formation of stars, there are some small celestial bodies around them that cannot be absorbed by them. These small celestial bodies absorbed some celestial matter within the scope of their influence and used them to strengthen themselves, slowly forming the current 8 planets.

And the role of the sun for them in the first place was to protect them from deorbiting when they were hit by celestial bodies. Because this is the only way to give them a stable light and heat**. <>

Of course, there are some unlucky objects in the middle, such as Mercury in our solar system, which is too close to the sun, so its internal water evaporates. In addition to providing us with a stable environment for growth, the sun can also rely on its gravitational pull to help us absorb many visitors from outside the sky. In fact, in addition to the sun, this star can protect the earth in the solar system.

Jupiter, which is far away from us, has also withstood several fatal impacts for us. Of course, if we are protected, we must not forget about our moon, after all, we have now found a large number of craters near the shadow of the moon.

The Sun protects us a lot, but there are still a lot of Saturn Jupiter protecting us, because Saturn Jupiter is in the outer circle of the Earth, and it has a lot of mass, which attracts a lot of asteroid impacts and protects the Earth.

It is the sun that protects us all the time. The sun's stream of energetic particles is released through eight planets, eventually forming a huge barrier to the solar wind, which blocks dangerous rays from the universe.

No, it is our own technology that protects us, and with the development of technology, rockets, satellites and other equipment can protect us.

The earth we live on is so small and inconspicuous for the universe. It is the sun that forms the solar system, which is equivalent to giving the earth a home. Sheltered by the sun inside and protected by Jupiter and Saturn outside, the earth is now stable.

The night is dark, and this is a matter of course, and this seems to be based on the foundation that the universe has a beginning. Because the universe has a beginning, it makes sense that the night can be so dark, and if the universe does not have a beginning, but has always existed, then the night should cease to exist. Why?

In our solar system, the light is brighter than our host star, the Sun, and in our solar system, the Sun is unique. However, if you look at our own galaxy, you will find that stars like the sun are not unusual, they are just too common. How many stars are there in the Milky Way?

Not 10, not 100, not 1000, but 100 billion.

This is still the most conservative number, with scientists believing that there could be up to 400 billion stars in the Milky Way. However, although the Milky Way is so large and has so many stars, it has no place in the entire universe, because there are so many galaxies in the universe that there are like the Milky Way, far more than the number of stars in the Milky Way, which is uncountable. There are countless galaxies in the universe, that is, there are countless stars, and these stars will emit light.

In the universe, there is no obstacle to the spread of light. So if the universe had not started and had always existed there, then the light of these stars would have come to Earth across a long time, and the light of countless stars would have come into our eyes, and the night would have ceased to exist.

But the reality is that the night is still dark, and although there are many stars, they are limited after all. And there is only one explanation for this, and that is that the universe does not exist forever, it has a beginning. Because if the universe were infinite, those glowing stars, no matter how far away from us, would reach the earth in an infinite amount of time, and the reason why their light has not yet arrived is because the universe has a beginning, and the universe has not existed long enough for the light of these stars to come to the earth, so we can't see them yet.

Since the universe had a beginning, how did the universe begin? The most mainstream saying in the scientific community is that the universe is great. Don't dismiss it, there is still a lot of evidence about the universe.

The reason why our earth is safe is because the earth's orbit will not be changed much in the short term, because the security for us is only stable in the next hundreds of thousands of years or tens of thousands of years, but for the entire solar system, for the entire universe, tens of thousands of years and hundreds of thousands of years are just a moment, so the solar system is changing all the time, but our human life span is relatively shortIn our view, the earth is stable in the short term, as it is saidCicadas

The solar system is not safe enough, our earth is also facing the danger of some meteorites, it is said that a few years ago there was a planet into the earth's gravitational field, there is a possibility of large-scale harm to hit the earth, but then changed the position, there is no direct impact with the earth, and now the aerospace industry of various countries is also developingThere are already some radio telescopes or something, which can observe planets that pose a threat to the Earth, and there are certain countermeasures, so the Earth is safe in the short term.

The solar system is safe for only one stage.

It's not that the solar system is safe, it's that human civilization is too low-level, and it's probably not as low-level in the galaxy, let alone the civilizations that the galaxy thinks it is.

Stable galaxies are generally safe.

The solar system of the universe is the home of the human beings of the global village! Nine planets, eight planets defend the earth to suck meteor showers from the universe, the language is 1 bird's nest of the solar system) That's it!

Because there is only one star in the solar system, the sun, and the sun is a yellow dwarf star in the prime of life, and at the beginning of the formation of the solar system, the eight planets blocked many dangerous asteroids for the sun, so the environment of the solar system is relatively safe now.

The fact that the universe is so dangerous and that only our earth itself is safe is a mistake in a particularly narrow sense, because no one at all now is interested in what the universe is like.

According to the analysis of some data, it is not difficult for us to find that compared with the tens of millions of stars in the entire galaxy, the Sun is just an ordinary yellow dwarf. Even so, the environment of the solar system is relatively safe.

Because the yellow dwarf star of the Sun is in its prime of life, its environment is relatively stable. The eight planets formed in the early days of the solar system also blocked many impacts from meteorites and stars in the galaxy for the entire solar system, keeping those troubles out.

Because there are not very many meteorites in the solar system. Moreover, the speed of the planets in the solar system is relatively slow and very stable.

Earth is a beautiful planet. If you look at the Earth from space, it looks like a water balloon with oceans, forests, lakes, etc. The reason why we can live safely on Earth every day is that it is in the center of the solar system, which has a relatively stable and safe environment.

SoSay, we are all benefiting from the solar system.

Why is the solar system always safe? According to some data analysis, it is not difficult to find that compared to the tens of millions of stars in the Milky Way, the Sun is just an ordinary yellow dwarf. Despite this, the environment of the solar system is relatively safe.

Because the Sun, a yellow dwarf, is in the heyday of its life, its environment is relatively stable. The eight planets that formed in the early days of the solar system also blocked many meteorites and stars from hitting the entire solar system, keeping these troubles out of the equation. Therefore, from the perspective of the entire solar system, its environment is much safer than that of the Milky Way.

In fact, there weren't many quiet years in the solar system. It's just that there are other stars to carry its weight. Thanks to the presence of eight planets, the solar system has avoided many troubles from external celestial bodies and meteorites.

Of course, the environment of the solar system is not absolutely safe, and the environment of other stars in the solar system is sometimes particularly unstable. For example, Jupiter is a celestial body that is frequently hit by other asteroids. According to news reports, in the 20th century, Jupiter was hit 90 degrees by a comet named Sumaker Klevy, which in itself caused great damage.

The attack left a deep rift in Jupiter. If this comet hits the Earth, the consequences will be unimaginable.

According to the data, the Moon is actually a scarred planet. I can't imagine how many planets and meteorites it has experienced. The Earth seems to be the "lucky one" in the solar system.

Due to the presence of Jupiter and the Moon, they are desperate to protect the Earth from outside attacks, so the Earth's environment is relatively stable and safe. Therefore, the earth is unique, and so are we.

There are many, many dangers in the universe, whether it is the inside of the sun all the time, or the meteorite impact of various planets, or the comet impact on the earth due to the disturbance of the gravitational field, it is a very dangerous behavior, but the life cycle of the universe is too long, and it is a very long time for human beingsBut it may be just a moment for the universe, and it may be a moment for the solar system now, and this time is calm, and the future is uncertain.

Since no one has been able to reach the solar system yet, it looks safe.

This is mainly because the earth is becoming more and more suitable for people to live as it develops.

This is because this is only a relative comparison and is not so directly certain.

This is not completely 100% safe, after all, the universe is still very large.

The solar system is not absolutely safe, just relatively safe relative to the rest of the universe.

Because the solar system is a relatively stable environment and there is no invasion of other foreign materials, the solar system is relatively safe.

For the vast universe, the solar system is just a small dwarf star, because the solar system can block some external impurities, and the solar system can now survive for at least 5 billion years.

No. Because the environment in the solar system is relatively calm, and humans are not yet that capable, it is not man-made.

It is not man-made, because there are many meteorites in the solar system, so if a rocket appears in the solar system, it is easy to be smashed through by meteorites. And there is the sun in the solar system, so the temperature in the solar system is very hot.

It's human-inflicted. Because there is a huge amount of space junk in the Earth's orbit. There are tens of thousands of pieces of garbage. It's all running at high speed. Touching a spacecraft or satellite. It was scrapped directly. Currently, the United States is the world's largest producer of space junk.

Hello, I am the pearl of wisdom and am happy to answer this question. Our universe doesn't revolve around the sun! The star Sun is large for Earth and seven other planets.

It has a diameter of about a kilometer, 109 times the diameter of the Earth, and a mass of about 200 billion trillion tons, 330,000 times the mass of the Earth. The Sun is undoubtedly the "boss" of the entire solar system, because its own mass accounts for the entire solar system, and the eight planets revolve around the Sun under the gravitational pull of the Sun.

So far, the farthest boundary of the solar system we have identified is the Oort Nebula, which is even farther away than the Kuiper Belt, and the light from the Sun would have to travel a full year to get there.

This is just a scene in the solar system, out of the solar system, after arriving in interstellar space, facing the vast sea of stars, there is no such thing as "the sun is the boss". There are many, many stars that are larger than the Sun. For example, the following diagram compares the size of the Sun to another star

Our solar system and many other celestial bodies move in an orderly manner in the Milky Way. The Milky Way is 100,000 light-years in diameter, with about 400 billion stars and numerous planets, moons, nebulae, star clusters, etc. The Sun is also here, on one of the spiral arms of the Milky Way, near the edge of the Milky Way.

The Sun revolves around the center of the Milky Way with all the members of the Solar System, orbiting the Milky Way once every 100 million years.

The Andromeda Galaxy, the closest galaxy to our Milky Way, is also more than 2 million light-years away. It is twice the size of the Milky Way. Together with the surrounding more than 30 galaxies, this galaxy cluster is formed.

The Lanikaia Supercluster, which includes the Milky Way and the Virgo Supercluster, has a diameter of about 500 million light-years and a mass 100,000 times that of the Milky Way. Our solar system is even more insignificant than it, like a grain of sand in ...... desert

It is the same for the entire universe, with or without a solar system. But the sun is very important for our survival, and without it, the earth would become a dark and extremely cold barren world.
