Why don t the stars in the sky collide?

Yes, although the universe is very vast, collision events still happen. If there is no interaction between galaxies, then the expansion will make the galaxies farther and farther apart. But galaxies do interact with each other, because when two or more stars are close to each other, the strong gravitational pull of their massive masses attracts other stars towards them; Gravitational forces overcome the expansion of space and bring stars closer to each other.

Neither our galaxy nor Andromeda will escape the fate of collision. That would be a very spectacular spectacle, but it won't happen in billions of years. Although the starry sky seems dense, in reality they are still very far apart, and the stars move regularly in the sky, not rampaging through the universe.

Therefore, it is impossible for the stars to collide, or the probability of them colliding is extremely small. <>

All the planets in the universe are orbited by compass orbits, and they will collide and merge only when their orbits are completed. This is a natural law in the universe, and no one can change it.

Each planet walks in an orderly manner, so it doesn't collide.

Just like us humans walking on the street, most of the time we don't collide with each other, but it is not excluded that we occasionally bump into others while walking on our mobile phones.

Wisdom determines everything, and it is enough to use the laws (forces) of the universe and the butterfly effect to adjust the working procedures of the universe.

There is no best tool created by human intelligence, only better, and you can't stop continuous progress.

We collide every day, we just don't see it.

Because every planet has its own orbital laws.

Because they're iron buddies!

Most people don't even look at it.

It has a fixed running path.

It's a long way from each other.

Because energy is conserved, there will be a certain distance between the stars, and this distance is eternal, and it will always be separated by this distance, so it will not collide with each other.

Because stars have their own orbits, and each star moves in the same direction, revolving around the center of the galaxy, stars do not easily collide with each other.

First of all, the stars that we can see with the naked eye are basically stars, and stars do not move.

In addition, the universe is so vast that each celestial body has a long distance between them, just like two cars running on the earth.

Finally, the possibility of a collision, such as an asteroid impact, cannot be ruled out.

Impacts do happen, but not as probability.

Worf: There are two reasons why the stars in the sky don't collide:

1.The space of the universe is so large that it is difficult for us to imagine, and the space for the movement of the planets is therefore very huge.

2.Large planets generally do not collide with each other because of the gravitational pull left and right. From the Earth-Moon system to the Milky Way and nebulae, they all move around a center and then translate over a larger scale. There is a general equilibrium between the planets.

3.Unless the planet fuses and dies, the shattering meteorite crashes into the next planet under the force of impact.

Equilibrium and action and reaction are two completely different concepts.

Gravitation can be a balancing force with electromagnetic force.

And the action force and the reaction force must be forces of the same nature.

Therefore, the reaction force of gravitation must also be gravitational force.

Within the framework of the universe, a planet moves under the action of complex forces ...

When the weather is clear, we can see a lot of stars in the sky, but the earth is not impacted, that is because the earth is protected by the atmosphere, in fact, the account period happens every day, but the friction with the atmosphere during the impact is burned.

The stars in the sky are far, far away from the Earth, and there is no need to worry about colliding with the Earth, they are all tens of millions of light-years away.

The star was just a little bit of light from other galaxies, far away from Earth, so it wouldn't hit.

Although the gravitational pull on Earth is great, these stars are stars that are far away from us even though we can see them (it can be calculated at the speed of light: 3x10 to the fifth power.

km s), the light emitted by a star takes about a few decades to reach the Earth, so the gravitational pull of the Earth alone cannot suck the star to the Earth. In addition, there are usually some meteorites that will land on the earth, and the earth's atmosphere is divided into troposphere, stratosphere, mesosphere, warm layer and outer layer (also known as the fugitive layer) (can also be divided into troposphere, stratosphere, middle layer, warm layer, is divided according to the change of temperature in vertical height), generally speaking, meteorites will burn out in the middle layer because of friction with the atmosphere before landing on the earth (this is what we usually see meteors), so there is generally nothing on the earth that falls from the universe d (Unless that thing is big, big, and hasn't burned out in the middle layer.)

To be precise, the stars are in space, including the Earth and everything on it; It's just that humans feel that the stars are above their heads, and they intuitively feel that the stars are in the sky.

Yes. The odds of a big star are very small, and they may only happen again in a few million years. However, there are countless asteroids walking in the space of the universe, some of which are fist-sized rocks, and some are large meteorites with a diameter of several hundred meters, which are also stars.

Every day, several tons and tens of tons of meteors fall on the earth, and most of them are incinerated due to violent friction with the atmosphere when they enter the atmosphere. There are some larger ones that fall into the sea and land.

Why can't we feel it?

Because there are relatively few meteorites that have not burned out, and 70% of the earth's area is oceans. The chances of falling in Haizhou Biyangli are greater. Even if it falls on land, because 90% of the land is not populated, we can't see it.

What we see"Heavenly"In fact, it is a vast and boundless cosmic space, in which there are a large number of celestial bodies and planets, some of which can shine like the sun, but because they are too far away from our earth, we can only see them at night, and they appear very small, which is what we call stars.

The stars in the sky are very far away from the earth where we are, and they are all several light-years away from the people in my group, for example, the Cowherd star is far away from the earth.

Light years, so the light we see emitted by the Cowherd Star is actually in.

Launched from the Cowherd Star a few years ago. The light emitted by the stars will pass through the atmosphere that protects the earth, the air in the atmosphere is not static, the hot air rises, the cold air falls, and the wind blows quietly, so that the density of each part of the atmosphere is different, the density is different, and the degree of light transmission is not the same, so it will cause it to look like the stars are twinkling in our eyes.

I've seen it in the dust"Heavenly"In fact, it is a vast and boundless cosmic space, in which there are a large number of celestial bodies and planets, some of which can shine like the sun, but because they are too far away from our earth, we can only see them at night, and they appear to be very small, which is what we call stars.

That's not the stars.

That's a different galaxy or nebula!

We can only see it as a bright spot with the naked eye.

There are still very few individual stars that we can see with the naked eye!

The stars we see are not real stars, but their projections on the celestial dome, which is why we look at the stars without feeling which star is far away and which is closer. During the day, the sky is bright, and the light of the stars is dim relative to the sun, so we can't see it.
