At 720 kilometers per hour, why are so many planets fleeing the galaxy?

Don't be misled by some headline party news.

First of all, the Milky Way has 1000-400 billion stars, and each star has its own planets, asteroids, etc., that is to say, the Milky Way has as many celestial bodies as there are sand by the river, and a large number of planets flee? What counts as a lot?

Second, the black hole, dark matter, neutron stars, white dwarfs and other high-density objects at the center of the Milky Way have a strong attraction, and together they maintain the operation of the huge Milky Way.

The strong attraction at the center of the galaxy and the expansion of the universe are mutual, in the interior of the galaxy, the galactic gravity is dominant, at most at the edge of the galactic galaxy, where the galactic gravity is weak, some planets will gradually break away from the galactic galaxy, but this is also a long process.

It is very difficult for the planets inside the galaxy to escape from the attraction of the Silver Heart, and not necessarily one of the 10,000 planets will be able to escape. Barring a sudden situation, the planet gains enough speed. For example, the star S5-HVS1 was disturbed by a black hole, and scientists observed that it is now traveling at a speed of more than 1,600 kilometers per second, exceeding the escape speed of the Milky Way, and the gravitational pull of the galactic center can no longer attract it.

The star is fleeing the Milky Way. But such a situation is rare in the interior of the galaxy.

Judging from the current data, it is only a conference to say that a large number of planets have escaped from the galaxy, as for how many billion years from now, who knows?

Because according to scientists' observations, the universe is expanding, and it is expanding at an accelerated rate. The expansion of the universe will make the planets farther apart, so there is a phenomenon that the planets are moving away from the Milky Way.

According to Hubble's theory of the expansion of the universe, the universe is expanding, and it is expanding at an accelerated rate. The expansion of the universe causes celestial bodies to move farther and farther apart until they break free from gravity and escape out of the Milky Way. But there are at least 100 billion stars in the Milky Way, and it is still far from disintegrating.

Because the Sun is expanding and getting closer to some of the planets, these planets are beginning their journey to escape the galaxy in order to protect themselves.

I think it's because there are bigger galaxies outside the Milky Way that are attracting them, or because of the lack of gravity inside the Milky Way, which doesn't attract these planets.

In the universe, there is a universal gravitational pull called the seal of God by scientists, and in order to escape the seal of God of a galaxy or planet, it is necessary to have strong power and fast flight speed, and this speed has different needs on each planet.

As far as the earth is concerned, human beings must reach the first cosmic speed and the second cosmic speed before they can break through the earth's god seal and fly into outer space. When the first cosmic velocity reaches kilometers per second, it can reach the lowest orbital altitude of the earth, and if it breaks through the second cosmic velocity of kilometers per second, it can gradually break away from the earth's gravitational control along the parabolic orbit. Currently, the rocket can fly at a speed of up to 7 12 kilometers per second and can pass through the first cosmic speed and the second cosmic speed.

However, at present, human technology has not yet reached the ability to conflict with the third cosmic speed, which is a standard of kilometers per second. After the vehicle reaches the third cosmic velocity, it can rush out of the solar system through a hyperbolic orbit and fly into outer space beyond the solar system. This rate has not yet been reached by humanity so far.

In order to achieve the fourth cosmic speed of flying out of the Milky Way, the speed and kinetic energy requirements will be greatly increased, and the speed must reach an ultra-high speed of more than 500 kilometers per second, such a flight speed that only some planets can reach from the currently known objects. In our galaxy, there are indeed a small number of planets that have reached ultra-high speeds of more than 500 kilometers per second.

In the entire Milky Way, the flight speed of our earth is still relatively slow, only reaching kilometers per second, and the flight speed of the sun is 240 kilometers per second.

About 20% of the stars in the Milky Way can fly at a speed of 450 500 kilometers per second, which is relatively close to the fourth cosmic speed, and the speed of the Milky Way should belong to a star that flies 1700 kilometers per second, which is the fastest star known in the Milky Way.

In the Milky Way, the planets that can reach a flight speed of more than 500 kilometers per second are almost concentrated around the center of the Milky Way, and they are controlled by the super gravitational pull of the Milky Way binary black holes, and they must balance the strong gravitational pull of the binary black holes by maintaining ultra-high speed flight with the inertia brought by flight, otherwise these stars will crash directly on the surface of the black hole.

Although near the center of the Milky Way, some super-high-speed stars are gathered, because they are controlled by the strong gravitational pull of the galactic binary black hole, these hypervelocity stars, too, have no way to get rid of the shackles of the galactic center, and they cannot fly out of the galactic galaxy at all.

From these data, we can see that the universe has been programmed to fix the planets in the galaxy, and they must operate within the specified range, and they do not have the ability to fly out of their own galaxy at will, this mysterious force controls the basis of the stability of all galaxies.

In addition to the earth in motion, the planets and stars in the sky are moving, they let Wang have their own orbits, the speed is constant, and the distance between the earth and the stars is very far.

The positions of the stars change, but they change so slowly that they are not visible to the naked eye.

The stars in the sky are changing, but we humans can't see them with the naked eye.

The fastest planet in the Milky Way is pulsars.

The fastest known wanderer is the pulsar because it is so fast. It has now left the center of the supernova 53 light-years away** and pulled a 13-light-year tail on its way. However, supernovae** occurred about 5,000 years ago.

Since its direction may not be affected by the gravitational pull of other stars, it is estimated that it will eventually emerge from the Milky Way and become a wandering planet outside the Milky Way.

The farthest planet from Earth

To date, the farthest planet ever discovered from Earth is a planet called "ogle-tr-56b". It was published on January 7, 2003 by astronomers from the Center for Astrophysics at Harvard University in the United States. The newly discovered planet is located in the constellation Sagittarius, 5,000 light-years away from Earth.

It is 30 times farther than the farthest planet previously discovered outside the solar system. More than several times the size of Earth, Burn Min is a hot gas planet similar to Jupiter, which is slightly smaller than Jupiter and only takes 29 hours to orbit its own star. "0gle-TR-56B" has been observed to be extremely hot, and its surface is covered with a large amount of molten iron.

The climate is very harsh. Previously, astronomers were only able to observe planets within 160 light-years of Earth. The astronomers who discovered 0GLE-TR-56B say the new technology used in their spine fissure will increase the number of planets that humans can observe from 40,000 to more than 100 million.
