Why does the sun not turn in space

The solar system orbits around an imaginary black hole of the Milky Way.

The Milky Way, on the other hand, is in motion, but not periodically.

All matter is separated and infinitely far away, and according to the grand theory of the universe, the universe is one before it was formed.

Singularity, and the ** force after the formation of the universe in the conditions of the vacuum.

The lower is infinitely extended, then all the matter in the universe is.

Extending wirelessly from the imaginary singularity in all directions, you can also understand that singularity as the central point of the universe.

Of course, this is just a judgment we make in the three-dimensional normal.

The solar system moves around the center of the Milky Way, and the Earth moves together. It's like if you're sleeping at home and you don't feel like you're moving, but you're flying through space at a speed of 250 kilometers per second.

Any celestial body is moving, immobility is only relative, each celestial body is rotating, and there will also be changes in the distance between celestial bodies, generally far away from each other. You may see that the sun does not rotate in the sky because: 1. Your means of observation are not up to it, and you cannot see the sun moving; 2 The time you observe is too short, and the sun also rotates relative to the earth.

The question of choosing a frame of reference is like when you are on Earth and you feel that it does not turn. Moreover, does it say that the sun does not turn? How can you prove that the sun is not rotating?

He should be the core of the solar system.

Rotation orbiting the Milky Way.

Here's why:

There is an important physical concept involved here, called "angular momentum". When the object rotates, the resultant external moment experienced by the whole system is zero, and the angular momentum of the object remains the same, i.e., "angular momentum is conserved."

Be an astronaut. Being in the space environment of microgravity, there is no contact with the space station.

He also does not stretch out his arm to help him turn around, which just creates an ideal state of conservation of angular momentum, when the upper body of the astronaut turns to the left, the lower body will "involuntarily" twist in the opposite direction. Therefore, without the interference of external forces, there is no way for astronauts to turn around.

The way space turns.

When an astronaut raises his arm to make a circle movement, the arm will produce a moment on the rest of the body, thus changing the rotation state of the body torso and making the human body rotate.

With the help of this arm, the astronauts can achieve the simple turning action of our celery on the ground. The friction between a person's foot and the ground when on the ground.

It will provide the torque and make it easy for people to turn around. From this experimental phenomenon, we can easily see that the rotation of the hungry body of any thing in the rotten stool requires the help of external moments.

The sun turns. The sun rotates, not only does it rotate, but it also rotates. The Sun rotates around its axis, and its direction of rotation is from west to east. The Sun rotates faster when it is close to the equator and slower when it is close to the poles.

The existence of the rotation of the Sun can be confirmed by the movement of sunspots and other active objects on the solar surface, such as sunspots, dark bars and spectral spots, or from the Doppler effect of the spectral lines on the eastern and western edges of the Sun. The direction of rotation of the sun is the same as that of the earth.

At the equator of the sun, the rotation is the fastest, and the higher the latitude, the slower the rotation, which indicates that the sun has a poor rotation.

The mass volume of the Sun:

The Sun is a huge, red-hot planet of gas. Knowing the distance between the Sun and the Earth, and then measuring the diameter of the angle of view of the sun's circle from the earth, we can find that the radius of the sun is 10,000 kilometers, which is 109 times the radius of the earth. From this, it can be calculated that the volume of the Sun is 1.3 million times that of the Earth.

According to Kepler's third law of planetary motion, astronomers can also calculate that the mass of the Sun is kilograms, which is 330,000 times that of the Earth, using the mass of the Earth and the radius and period of its orbit around the Sun.

And concentrates the mass of the solar system. However, even such a behemoth, in the vast universe, is just an ordinary star of medium mass. <>

Because the average density of dust in the universe is extremely low and cannot play a significant role in refraction, the slightest wisps of sunlight through the clouds cannot be seen in space, nor can the so-called light be seen, but the light itself still exists.

Sunlight, broadly defined, is electromagnetic radiation from all spectrum of the sun. On Earth, sunlight is obviously the solar radiation that is filtered by the Earth's atmosphere above the horizon and onto the Earth's surface.

When solar radiation is not obscured by clouds, it is often referred to as sunlight when it is directly illuminated and is a combination of bright light and radiant heat. The World Meteorological Organization defines "sunshine hours" as the irradiance of sunlight directly received by an area at more than 120 watts per square meter.

Because the energy of the universe is very large, and the planets have forces with each other, the sun will not fall because of this force.

Everything has a gravitational force, big or small, for example, the gravitational force of the earth is very large, which can ensure that you will not jump too high, however, the pre-gravitational force of the moon is only the earth 1 6, on the moon, you can argue that the people can float up, the same reason, the sun can also be suspended in the air all the time.

Because there is a vacuum in space, there is no gravity, so the sun does not set.

The reason for the occurrence of universal repulsion force (brief description): When the high-energy particles running in the universe pass through the matter (celestial body or particle), some of the high-energy particles that are intercepted and absorbed interact with the matter (celestial body or particle), and realize the energy exchange according to the law of conservation of energy conversion mv2=e=mv2, and radiate the corresponding material energy, which is formed in the surrounding space"into energy superposition", i.e., the strong energy zone. This strong energy zone is"Repulsion"Range.

Due to the prevalence of this kind in the cosmic space"Repulsion", so it is also called"Repulsion"。

That's because the universe contains a gravitational force, and these two gravitational forces can reach a kind of equilibrium, so it rotates around.

I don't know exactly how this principle is, but the mysteries in the universe are endless, and there are so many things in it, so we need to read more books at this time.

The main reason is that the earth is some distance from the sun, and the earth is in orbit, of course, it will not fall into the sun because of the sun's gravitational pull.

The Sun is a star and does not revolve in the universe like a planet. However, there is a phenomenon on the surface of the sun called"Equatorial deflection"The phenomenon that the equatorial region of the sun before the sun is burning is rotating faster than the polar region, which can lead to the misconception that the sun is rotating. This equatorial deflection phenomenon is caused by the movement of plasma on the surface of the sun, which causes the plasma to be smoothed due to the uneven rotation speed of the sun"Drag"up, producing rotational motion on the surface, this process is called"Differential flow"。

Therefore, although the sun itself does not rotate like planets, the phenomenon of equatorial deflection on the surface can still give the impression of rotation. <>
