Why do massive stars in the universe always tend to be spherical in shape?

The shape of massive stars in the universe always tends to be spherical, this is because everything is controlled by a gravitational source, and the greater the gravitational force, the greater the mass that gradually approaches, which is also what many astronauts have left in the photograph to understand.

Because spheres can have a very large density in the smallest space, so that the mass can reach a large amount, the shape of massive stars in the universe always tends to be spherical.

Answer: The shape of massive stars in the universe always tends to be spherical, which is determined by the law of gravitation, under the action of gravity, the shape of massive stars tends to be spherical stars.

A circle is the most beautiful flat figure, while a ball is the most beautiful three-dimensional figure. Therefore, this form without edges and corners is more likely to make a revolution or rotation when the star is moving. In tens of thousands of light-years of evolution, those massive stars have formed a more suitable shape for this sphere.

It's like the convergence of a drop of water. In the process of rotation, massive stars in the universe will also form spheres little by little due to the effect of attraction. And the action of tidal forces will also cause it to change its shape.

<>1.According to the singularity ** theory.

and the law of immortality of matter, although the universe continues to expand, producing trillions of planets, they are all singularity masses, and the total mass remains the same. Just like blowing up balloons, the quality of closed group sales without balloon blowing and balloon blowing is unchanged. The first statement, of course, was the imagination of the astronomer Lemaître, according to the fallacy of Obers and the red variation of Hubble.

There is a lot of controversy in this world. If scientists guess that the universe is infinitely static and constantly changing, then the mass of the whole will remain the same. Because all matter is unchanging.

2.The universe is so big that humanity can't imagine how many galaxies it has.

and unreachable by humans**. Even the best astronomical telescopes for mankind.

The contents of the universe are also not visible because their light cannot cover the galaxy in which the Earth is located. What humans see is a small corner of the universe. Therefore, we cannot talk about the overall mass of the universe as known by man.

New nebulae are constantly emerging. In fact, this is not a new nebula, but a new upgrade of human vision technology.

3.The sun is a plasma hydrogen balloon.

It relies on the elements that burn hydrogen to produce energy, which after combustion releases a new substance, namely helium. In the process, the hydrogen gas in the early days is depleted, and this part of the mass star disappears. But stars acquire a new mass, and that is helium.

Helium also produces nuclear fusion.

It then fuses into heavier metallic elements.

When these elements eventually turn into iron, because the process of iron fusion is quite complex, the stars are unable to integrate iron, which is a very heavy element.

4.The life and death of stars on different time scales.

It also changes over time as stars produce different elements as they go through life and death. Stars require several different processes to make elements, which are in the periodic table.

Interestingly distributed. When we think of the universe, we think of how many stars have sacrificed our lives, and not just massive stars** that have become super-new stars.

The total mass of the universe has not become larger because everything in the universe follows the law of conservation of energy.

According to the singularity theory and the law of material immortality, although the universe continues to expand, producing trillions of planets, it is the mass of the singularity, and the total mass remains the same.

Mass is the quantity that can be argued, Einstein's famous mass-energy equation is about the conversion of mass energy, and the physical law that we know now is that energy cannot be generated and destroyed, so energy has been conserved, and the overall mass of the universe remains unchanged.

You could be wrong, but in fact the vast majority of the universe is overwhelmingly ......Most of the stars — well, I don't know how many vast majorities are needed to describe them precisely — aren't spherical. The stars we say are objects in space, and what we see seems to be all spherical - the sun, the moon, the big planets in the distance, the planets that are even more unreachable, as if they are as round as they should be, the earth is long, and the perfection is so perfect that people are thrilled and cry secretly - maybe every person who has just gone to space has not been touched to tears.

But if your eyes can become thousands of times, hundreds of thousands of times bigger, and see deeper objects hidden in the vast space, you will find that there are countless stars in the vast expanse of black, including planets, meteorites, etc., flashing in the lonely space - these are stars in the traditional sense of meteorology, as long as they are not objects on the earth, most of them can be called stars.

Therefore, in the solar system, at this stage, only dozens of stars such as sunlight, eight planets, dwarf planets and communication satellites of some large planets are spherical, and more stars - the asteroid belt between the orbits of Mars and Jupiter, the Kuiper belt, the discrete disk, and the Oort cloud have the least understanding of 100 million planets and meteorites, the largest one is hundreds of kilometers, the smallest is a few meters, a few centimeters, not spherical, in terms of the total number, the vast majority of stars in the universe are not spherical.

More stars, such as planets and star orbits, galaxy clusters, superclusters, and large-scale structures, are not spherical in the true sense of the word. Only planets, large planets, and planets with a half-longitude of about 500 kilometers can be gathered into a spherical shape under the action of gravity, and the more mass, the more extreme the ball; White dwarfs, neutron stars, and superblack holes formed by the collapse of stars after death are all perfectly spherical. Well, it's not that extreme, all of these stars have to rotate under the angular momentum they gain when they are generated, or the gravitational force between them, and their collisions, and become ellipsoidal under the influence of centripetal forces - the Earth's equator is raised, and the secondary dents are notched, even if it is a super black hole.

Therefore, strictly speaking, there is actually no star in the universe that is perfectly spherical, and it all depends on how fine you look at it, after all, there is no star that does not rotate at all.

Like our homeland, the Earth's equator is a kilometer greater than the pole's half-longitude, and the sunlight becomes about a kilometer; Jupiter and Jupiter are ellipsoidal because of their rapid rotation; The most exaggerated is 13.9 billion light-years away from the earth, the ninth light planet in the sky, because the personal biography is very fast, the diameter of the earth's equator is 56% larger than the polar aperture, each times and times the sun, it is simply a super giant basketball; And the most exaggerated is Yaoguang 14A, which moves at the equator of the earth at 152 times the speed of our sun, and has been broken up into an extremely oblate sphere, experts may move a little faster by 10%, and it will be torn to pieces by its own centripetal force.

Not all celestial bodies in the universe are spherical, only planets with a certain mass will be spherical, and most of the planets are not perfectly spherical, for example, the earth is an elliptical planet, the shape of the planets is difficult to present a perfect spherical shape, and the shape of most stars will be closer to the spherical shape, and the more massive the celestial body shape, the closer to the perfect shape.

More than 5 million years have passed since the birth of human beings, and in these millions of years, human beings have multiplied on the earth and human civilization has flourished on the earth. Since the time of our ancestors, every time human beings look up at the starry sky, they will be full of curiosity about the vast universe above our heads, from the very beginning of the earth as the center of the world to the current cosmic theory, our ancestors have never stopped exploring the universe.

Everyone has their own answer in their hearts, but "circle" is definitely the one with the most votes, the circle and the spherical represent the perfection, 360° is the whole space, there is no dead end. The ancient Greek philosopher Plato also believed that the most perfect and harmonious form of the universe is the sphere, and he believed that the land under our feet should also meet this harmonious form, and boldly predicted that the land under our feet is spherical.

I think the reason for this is that our spinal environment has been damaged a lot, so many places have begun to deteriorate, and the weather has begun to have frequent problems.

The vast majority of celestial bodies in space are spherical or spherical because of the difference between the light in the air and the sight of the naked eye. You could not be more wrong. In fact, most celestial bodies in the universe don't know how large it takes to accurately describe how spherical they are.

The so-called celestial bodies are all objects in space. What we see appears to be the spherical sun, moon, distant planets, and more distant stars. They all seem to be perfect circles, perfect enough to bring tears to your heart's eye.

It is estimated that everyone who goes into space for the first time will not cry. However, if your eyes can magnify thousands, tens of thousands of times, you will be able to see more celestial objects hidden in the vastness of space, and you will find countless celestial bodies twinkling in the solitude of space, including asteroids and comets—these are astronomical objects, but objects that are not part of the Earth can generally be called celestial bodies.

The vast majority of celestial bodies in space are tear globs or ball stars, which is formed after the baptism of time, if the celestial bodies in the universe are square or cylindrical, it will cause a certain degree of resistance and hindrance to the operation of celestial bodies, so for the operation of celestial bodies, it will be more in accordance with certain laws and trajectories as a spherical shape.

We know that stars are formed from primordial nebulae, and in our solar system, for example, the celestial bodies of the solar system were born with the birth of the sun. At the beginning of the formation of the sun, due to the gravitational force, the nebula will slowly shrink towards the center and form a vortex, when the stellar disk composed of a huge molecular cloud continues to rotate in the center, the mass and gravitational force of the original star will increase more and more, the inner center is centered on the center of mass, and the gravitational force in all directions is equal, that is, the force is balanced, thus forming a sphere.

Because the matter on the stars is gravitationally attracted and gathers towards the center, most stars are spherical. Because some asteroids are small enough to gravitate enough to change shape, not all matter exists as spheres.

In general, the reason why most of the relatives in the universe are stars may be because of the rules of the universe, in some ways, spherical objects are better suited to survive in the rain, and in most cases, if they get rid of the spherical shape, then due to gravity, the object will also appear as a broken star, so it is said that the star is better to establish equilibrium and can maintain the state of a planet. In general, there are several reasons.

All matter has a central point, and the only way to get close to it is to be spherical. Not all matter exists in a spherical shape.

Answer to question1:

This is true of the Earth and the eight planets.

First, the circle is the most stable and perfect shape. Planets, especially large ones, must be round in order to maintain their own balance;

Second, the influence of gravitational force. There will be a lot of matter on the planet, in order to ensure that these substances do not fly out, these substances have to be pulled into the center of the planet, which is the gravitational force, under the action of gravity, the planet will become circular over time;

Third, the movement of the stars in the air is mainly revolution and rotation, and the raised corner will be thrown away in the process of rotation, and the stars will slowly become round;

Fourth, the star is formed by absorbing tiny particles in rotation, and the small star rotates around the large star, and finally is swallowed up by the large celestial body, and so on, and finally becomes a large circular star.

That's when you don't see asteroids in space, many asteroids are irregularly shaped, some comets made of ice and dust are also irregular in shape, and some binary galaxies are elliptical because of the gravitational influence of each other.

This is called "nature", the creation of celestial bodies.

Maybe the reader is your teacher.

Stellar: The most typical is the Sun, where the maximum temperature on the surface of the star can reach 40,000 to 70,000, and the lowest is also in the thousands of degrees Celsius. In this case, there is no solid, liquid matter on the star, but some gaseous state.

The gas diffusion is the same in all directions, and the range is roughly equal, and the gas in all parts is controlled by gravity. So when these forces are balanced, it has a spherical appearance, which is one reason why the stars we look like are round.

Planet: It does not emit light per se, it is not a star in a gaseous state, but a hard solid sphere. But when it was just taking shape, it was also a red-hot molten substance.

Because it has a rotation, it changes its shape to be spherical or oblate. The spherical shape thus formed is mechanically called a "rotating sphere", or "rotating ellipsoid". The moons of the Moon and some other planets are also round and oblate in shape.

Of course, in the universe, in addition to stars and planets, there are also some nebulae, asteroids, moons and other celestial bodies, these celestial bodies are not spherical, but show an irregular shape, but because the number of these celestial bodies is not large, most of our planets are round.
