In the theory of relativity, is the velocity of the planet autobiographical or the rotational veloci

The speed of relativity in discussing the extension of time and the increase of mass is neither the autobiographical velocity of the planet nor the orbital velocity of the planet around a certain celestial body.

The velocity used in the theory of relativity is the relative velocity of an object in motion relative to a certain body (which can also be the velocity relative to the earth), and the state and speed of motion of the earth itself are not considered. For example, in the famous "Twin Sons Paradox", one of the brothers stays on Earth and the other travels in a spaceship for long distances close to the speed of light. As a result, when the traveler returns to Earth, he finds that he is younger than his brother who stayed on Earth.

This is a corollary from the special theory of relativity, the time extension effect of moving objects (also known as the "time dilation phenomenon of a moving clock").

When discussing such problems, the speed of motion of an object has nothing to do with the motion of the earth itself, because the motion of the earth, whether it is rotational or revolutionary, is far from the speed of light relative to the speed of motion, which is close to the speed of light, and is almost indistinguishable from the state at rest, and can be regarded as having zero time dilation.

Time to stop when the speed of light is reached:

Suppose there is a long enough stretch of straight road, and you are standing in Ground A and you are moving at the speed of light from Ground A at 12:00 on time. The moment you start to move forward, everything that happens in Ground A is spreading in all directions at the speed of light.

Ten minutes later, at 12:10, you arrive at B. At this time in the first place 12:

The phenomenon that happened at 00 clock also happened to spread to place B, so if you look back at the phenomenon of 12:00 in place A, no matter how long you have advanced, you will always see the phenomenon of 12:00 in place A when you look back.

This is the phenomenon of time stopping.

Going back in time beyond the speed of light:

If there is a long enough stretch of straight road, and you are standing in place A and you are traveling at 2 times the speed of light at 12:00, then after 10 minutes you reach place C, it is not difficult to find that it takes 20 minutes for light to travel from place A to place C, which means that the phenomenon that occurs at 11:50 in place A is at 12:

10 minutes to reach C. Then you see at 12:10 in C and A at 11:

What happened in 50, the phenomenon of turning back time just happened.

Relative Time Formula:

Let the speed of starting from place A be v, the forward time is t1, and the time to see the phenomenon of place A is t2=t1v c. Relative time t=t1-t2=t1(1-v c).

As can be seen in the formula, v=c, t=0. Time stops; v>c, t<0, time rewind.

The speed of light cannot be surpassed by the theory:

Suppose there is a long enough stretch of straight road, and you are standing in Ground A, and at 12:00 you are moving at twice the speed of light, and there is a person in Ground A watching you. After 10 minutes, you reach place C, and it takes 20 minutes for you to reach place C before it can reach place A.

In this way, the people of Ground A will not see you reach Ground C until 12:30 and thus conclude that your speed is 2 3 times the speed of light.

Let your velocity be v, the speed of light be c, the distance s, the time you travel t1=s v, and the time when the phenomenon is transmitted back to the first place after reaching t2=s c, we can get the speed at which the people in the first place see you as.

v1=s/(t1+t2)=s/(s/v+s/c)=vc/v+c。

As you can see from this formula, no matter how high your velocity v is, it seems impossible to reach the speed of light. It only appears to be the speed of light when your speed is infinity.

Velocity is not an isolated concept, it is relative to a frame of reference. If you understand this, you will know whether it is a rotation or a revolution or the speed relative to the earth and the sun. It depends on the specific description of the problem condition. Hope it helps.

Rotation period. At the equator: about 27 days, 6 hours and 36 minutes.

Latitude 30°: 28 days, 4 hours and 48 minutes.

Around the center of the Milky Way.

The revolution period is about 10-8 years.

seconds) solar constant f = cal·centimeter 2·min -1 spectral type: g2v

The surface of the sun is detached from the velocity.

618 km sec.

The earth is too auraly bent near the sunny wind.

Speed: 450 km/h.

The speed of the sun's motion (direction = 18h07m, δ = 30°) = kilometers and seconds.

Mercury is the fastest, and the closer the Sun is, the faster it will orbit. When the landlord learns the chapter on gravitation and circular motion in the first year of high school, he will know that the celestial orbital motion of the celestial body orbits, the linear velocity, and the square root of the distance, are inversely proportional.

The planets of the solar system move the fastest with Mercury, and the closer the Sun is, the faster it rotates. The rotational speed is not the same.

The period and average orbital velocity of the eight planets around the Sun are as follows:

Mercury has an orbital period of days and an average orbital velocity of kilometers per second.

Venus has an orbital period of days and an average orbital velocity of kilometers per second.

The Earth's orbital period is 365 days, 5 hours, 48 minutes and 46 seconds, and the average orbital speed is 30 kilometers per second.

Mars has a rotational period of days and an average orbital velocity of kilometers per second.

Jupiter's orbital period is days, about years, and the average orbital velocity is kilometers per second.

Saturn's orbital period is about a year, and its average orbital velocity is kilometers per second.

Uranus has an orbital period of about 84 years and an average orbital speed of kilometers per second.

Neptune's orbital period is about a year, and its average orbital speed is kilometers per second.

From the above, it can be concluded that among the eight planets in the solar system, Mercury has the fastest average rotation speed.

The angular velocity of the Earth is approximately a minute (angle) hour.

The angular velocity of the Earth's rotation is one-twelfth (180 degrees of radians corresponding to 180 degrees) of the Earth's angular velocity except for the pole, which is 15 degrees per hour

Hope it helps.

There are already some people who are very good, so I won't repeat them.

The earth revolves around the sun, the sun revolves around Sagittarius a' Sagittarius a revolves around the Milky Way and the Milky Way revolves around xx, xx around the virgo around xx

The Milky Way is located at the edge of the local supercluster.

The Supercluster is the most advanced celestial system (the total galaxy is not a celestial system) and has only rotation, not revolution.

Sagittarius A is how the sun orbits the Milky Way. The questions are all wrong (the sun revolves around the solar system?). ）

1。The revolution of the Milky Way is not currently known to detect a point around which the Milky Way orbits.

If anything, it's a point in the center of the local galaxy group. The Local Group contains more than 50 galaxies. 10 million light years in diameter.

The Milky Way is 160,000 light-years in diameter. It takes 100 million years to rotate. It can be reversed beyond the age of the universe.

And the speed of movement is too slow to measure.

2。"The earth not only revolves with the sun, but also with the sun, and with the galaxy."

There is a reference for speed. You can't take two references to say the velocity of the earth false proposition.

The speed of movement relative to the Sun Earth is 30 km s, the speed of movement relative to the Milky Way Earth is 200 km s, and the relative speed of the group of galaxies may be thousands per second, (unmeasurable).

According to the current theory, the universe is not static, that is, there is no particle as the center of the universe, and it is now believed that the universe is expanding or contracting, which means that the Milky Way does not necessarily revolve around a certain mass point. There is also the fastest galaxy that is closest to the center.

First of all, there is no such thing as a "cosmic particle", and there is no concept of rest in the universe. Everything from cosmic dust to superclusters of galaxies is in motion, and to examine which level of motion is to establish a frame of reference. In addition, all motion is relative, and there is no so-called "cosmic particle" that applies to all levels.

This is a product of the absolute view of space-time in Newton's time. Moreover, your guess that "hundreds of millions of years of human concept of time is only 1 second at the rest point of the universe" completely misunderstands the relationship between the speed of motion and the rate of time - on the contrary, the lower the speed of motion, the faster the rate of time.

Secondly, all you want to know is how high the linear velocity of the revolution and rotation motion can reach, and there is no need to investigate the behavior of ordinary celestial bodies (such as the Earth, the Sun, the Milky Way, etc.), because the maximum velocity in the universe always occurs near those extreme objects (such as neutron stars and black holes), or in large-scale fields (such as cosmological expansion), and the speed involved in these cases is much higher than the linear velocity that can be achieved by the revolution and rotation of ordinary celestial bodies. For example, the inner edge of a black hole's accretion disk orbits very close to the speed of light; The redshift value of distant quasars has reached z=11, which has been exceeded. In contrast, the linear velocity of the first level of the galaxy cluster is only on the order of kkm s, less than that.

Finally, there is no such thing as a "time twist". The general theory of relativity explains the nature of time, which can expand or be compressed, i.e. faster or slower, but this effect also occurs between two objects in relative motion, and there is no absolute expansion and contraction of time.

I know that the speed of the earth seems to be.
