The shape of the sun and the earth, and the major planets are all in circles, so what is the shape o

Black holes are also different from black holes, black holes are the inward collapse of stars, the atomic structure in the star is completely destroyed, and the neutron star structure cannot withstand its own huge gravitational pull, and continues to collapse inward infinitely to produce black holes, that is, huge masses concentrated in tiny volumes. If the volume is close to 0 and the mass is infinite, then of course it is ideal, in fact it still has a volume, which depends on its mass, because the mass determines the degree of its collapse.

Forget about the shape, the area of space where the black hole is located cannot even shoot light, even against a white background, you can only see a black hole in this universe, and the shape of the celestial body itself cannot be seen.

Non-rotating black holes are theoretically perfectly spherical

But when a star collapses into a rotating black hole, it should be an oblate sphere (centrifugation?) like a normal star. And then you can't see the black hole (which doesn't need to be explained.) As for volume, it refers to the range in space Since it is bounded by the event horizon, and there is a critical radius (Schwarzschild radius), then of course there is volume.

In addition, many people don't seem to be careful when they read books and always equate black holes with singularities What is said that black holes are infinitely small in size and infinitely large in mass, and in theory it just says that there is no naked singularity, but can only exist in black holes or big ** points. (This is a good way for the theory to deal with the problem of infinity and the inability to know the inside of a black hole).

Again.. The size of a black hole has nothing to do with whether it is a space-time tunnel or not!! For now, black holes aren't very rosy as time tunnels, but the distorted space of a black hole's powerful gravitational field is a good idea for time travel

Let's put it this way, you can see the Earth, the Sun, Jupiter, and so on because they can reflect light or they can emit light. Have you heard of the definition of a black hole (what exactly is it, check the information yourself, go to the information and don't explain it here)?Not even light can escape the gravitational pull of black holes, which are places where space-time is distorted.

The gravitational pull of general relativity is not a force at all, but is the result of the fact that space-time is not flat. In other words, it is impossible for light to escape a black hole, so do you think you can see it? If you have to ask, I can tell you that a black hole can never be a polygon, and the event horizon of a black hole is curvature, just like the Earth.

In this correction, your concept is not that a black hole is a space-time tunnel, but that the wormhole in a black hole can teleport, and you can understand that you are sucked into a black hole (of course, the gravitational force of the black hole on your head and feet has already broken you into pieces, but your particles will not disappear), then your particles may suddenly appear in another space-time, and this distance may be several light-years or hundreds of light-years or even thousands of light-years. It's not that black holes can do time travel. In terms of current physical theories, time travel is impossible, because time travel and theory are in great conflict, and you can look for information about time.

A black hole is not round, it is a honeycomb shaped by many angular edges, which swallows the surrounding medium to complete its shape (it seems to be 25 billion years old, older than the age of the universe), but it seems that the black hole has not yet been filled, so naturally there is none.

It may be circular, elliptical, and it can be seen as a very dense planet. If you really want to know, then go to the top and feel it for yourself, feel it with your hands, but it seems that there is only one chance, and whether it will succeed is unknown, because no one has tried it, and only he knows if he has tried it in time.

It is also basically spherical. In other words, it is a small ball when viewed from top to bottom, left and right.

Theoretically, it's round.

If you've ever looked at the ** of our planets, or looked at them in a row, you've noticed something interesting – all planets are round. Naturally, you might ask, "Why are planets round?"

The answer to this question lies in the two questions of how planets form and how gravity works.

When rocks, atmosphere, and dust begin to meet in the universe, some of them begin to stick together or clump together. When all these rocks, dust, and atmosphere gather, they create their own gravitational pull that will bring all of this together. The planets that are forming are very hot, even lava.

Then gravity starts acting on these hot and molten substances. The gravitational force is the same in all directions. Because the gravitational pull is emitted from the center of these substances, these outer layers of matter are pulled towards the center in the same way, and eventually they form a spherical shape.

As the massive, extremely heavy mass begins to crash towards the center, the melted mass and pressure begin to push outward. The inward gravitational force and the outward pressure create an equilibrium. This balance is made and maintains the shape of a sphere.

After these substances have cooled, it still retains its spherical shape. That's why our planet is round. However, they are not strictly spheres.

As the planets rotate, there will be some bumps in their circles. The faster the planet rotates, the bigger the bulge. This means that a planet that spins rapidly may not be as round as the others, and may even be a little flat.

In addition to this, some objects also affect the planets, forming impact craters in the representation of the planets.

For comparison, you can look at asteroids. Smaller planets tend to be round. In fact, they are jagged, fragmented, or other irregular shapes.

This is because smaller asteroids have only a very weak gravitational pull, which means that they do not attract matter in the same way in all directions.

The planets are round because the center of gravity attracts all the matter with the same gravitational pull. But not all planets are exactly spherical. They are not perfect in shape and surface, but they generally maintain their round spherical shape.

At the beginning of the formation of large planets, because they contain a certain amount of fissionable heavy elements, the fission reaction of these elements produces a huge amount of heat energy, which melts into magma and forms a spherical shape under the influence of its own gravity.

Needless to say, small planets are fragments of planets that have aged, cooled down, and cooled and hardened in their bodies collide with each other, and there are different shapes. Large planets were formed as a result of the eruption of a cosmic black hole. The black hole inhales a large amount of stellar material, and the heavy elements and iron in the star will be ejected from the center of the black hole with the explosion of the black hole, and then attract each other to form planets of different sizes.

If the area where the black hole material is ejected contains more hydrogen, the larger planets formed by these materials attract hydrogen to its surface and compress it into a liquid state, which further increases the mass and gravitational pull of the planet, and attracts more hydrogen. The structure is similar to Saturn-Jupiter. Finally, hydrogen becomes the most abundant ingredient.

Multiple giant "hydrogen stars" attract and collide with each other, and finally merge into a giant star. Our solar system was formed by the eruption of a black hole in the Milky Way. It is a quadratic star with a small mass and a short formation time.

When the universe was large, countless huge stars were formed, much larger than the sun, and burned rapidly, and many stars have evolved into giant black holes.

Because the celestial bodies that can be called planets are all celestial bodies with a certain physique and mass, their gravitational attraction is relatively large. Because the force that affects its formation is mainly its own gravitational force, the matter added to it will be distributed under its gravitational force, and they will receive different attractions at different heights from the center of the sphere; At the same distance from the center of the sphere, it is basically the same.

It is precisely because of this that the force that tends the matter to the center of gravity shapes them into a spherical shape, because mechanical equilibrium is the rule of the game, and only when the mechanical balance is in balance, it can be stabilized, otherwise it will continue to change until it is stabilized by equilibrium.

There are many kinds of planets, and here let's take our home, the earth, to interpret it: although the earth is a ball, it is not a sphere, but an oblate sphere. Observations from artificial Earth satellites show that the Earth's equator is also elliptical. Thus, the Earth can be considered as a triaxial ellipsoid.

Currently, it is believed that the Earth originated from the solar nebula 4.6 billion years ago. The formation of the Earth, like other planets, underwent a series of physical evolutionary processes such as accretion and collision. At the beginning of the formation of the earth, the temperature was low and there was no layered structure, but the temperature of the earth gradually increased due to the impact of meteorites and other materials, radioactive decay leading to heat release, and the gravitational contraction of the primitive earth.

As the temperature rises, the phenomenon of molten nuclei begins to appear in some parts of the earth, and the plasticity of the earth's internal materials becomes more and more large. Under the action of gravity, the matter on Earth begins to separate. As written in mythology, the heavier objects on the outside of the earth gradually sink to the center of the earth, forming a denser core.

The lighter substance inside rises gradually. With the large-scale chemical separation activities, the earth gradually formed the current structural layers of the crust, mantle and core.

We can understand that no matter whether the material of the planet rises or falls, its directionality causes the phenomenon of the planet being almost spherical. Matter sinks, as if any point on the surface of a sphere moves to the center of the sphere; The matter rises, as if the center of the sphere moves to any point on the surface of the sphere.

Whether it is the rise or fall of matter, it must be aided by one point, that is, the plasticity of the overall material of the planet becomes higher, which is the premise.

This has something to do with its journey with the source states, because there is some gravitational attraction on these planets, which will attract some things to attach to the body, and slowly form a split sail into a sphere.

The formation of celestial bodies is derived from gravitational slip, and its shape is also mainly related to gravity. Everything in the world is made up of tiny particles, which are gathered into clumps under the action of gravity, and eventually snowball.

Because these planets have a fixed orbit, if they are not round, they are not planets. Some planets will have other shapes. But these planets are not planets.

There are other shapes, the earth is not a complete spherical shape, it is a more concave and convex shape, such a shape is more stable than the repentance, and can wrap the magma well.

There are many things in the universe that revolve around a center regularly, from the inside of an atom to the electrons that revolve around the nucleus, to planetary celestial bodies, such as the earth and the moon, where the moon revolves around the earth and the earth is the center; In the solar system, celestial bodies such as planets revolve around the sun, and the sun is the center; In the Milky Way, the black hole at the center of the Milky Way can be said to be the center of the Milky Way, around which all stars orbit. What about our universe? Does it have a center?

Doesn't it run like a star?

Unfortunately, the universe is not the same as galaxies, and it is likely that there is no such center, at least in terms of observational data and theoretical research, scientists have not found it, and do not believe that the universe has a center.

So why is this happening? The reason for this has to start with the beginning of the universe.

The scientifically recognized and scientifically reasonable theory to explain the universe is the great universe, which is also a theory that has been proven by many observational data, this theory believes that the universe began at a very small point, and the evolution of the universe began in a large **, and gradually formed the current universe. And at the beginning of the universe, it didn't leave itself anything that it didn't have, so it wasn't strong enough to control the center of the entire universe.

The universe is a whole, the energy contained in the original energy ball of the universe is scattered, and the energy is scattered in the vast space, and the activity and temperature of the energy begin to decline, so these energies gradually form matter, and gradually form a large-scale nebula, in which primordial galaxies such as the Milky Way were born, and these galaxies produced powerful black holes in their own motion, and some may be the original black holes at the beginning of the universe, These black holes gradually dominated the galaxy and became the center of the galaxy.

In these galaxies, each star also forms its own operating system in its own space, so a star system such as a stellar planetary moon is formed, which is very similar to the structure of an atom, a star with a strong mass is like an atomic nucleus, and a planet is like its electron.

And this phenomenon is very popular in the universe, almost all the matter in the universe operates like this, from the large galactic celestial bodies to the small inside the atoms, all of which are centered on the powerful mass, so why has the universe not formed such a state? We can imagine that a firecracker does not leave a strong center for the smoke and debris to follow it.

So if the universe should have a center on its scale, this should be correct, because the universe as a whole must have a central part in volume, but this central part may be no different from other places.
