The Milky Way is heading towards the Great Gravity, but what is the meme that it will never reach?

The meaning of this meme is that the Milky Way has been rushing towards the giant source in time, but it will never reach the giant source, which can be understood as an impossible thing.

Many galaxies in the Milky Way are moving towards the giant gravitational source, and it will take more than 200 million light-years to reach it, but the universe is not static, and the giant gravitational source is also moving all the time, so it is basically impossible for the Milky Way to reach it.

From the point of view of physics, the Milky Way is rushing towards a giant source but cannot reach it, and this problem can be solved by the relative motion and relative rest of the objects, which may not be done in a practical sense.

Objects are relatively moving and stationary, the Milky Way is moving, and the giant gravitational source is also moving, and the two remain relatively stationary, so the Milky Way and the giant gravitational source will not meet.

It's not a run, it's a fall! People always wonder why the celestial bodies in the universe float in the air and do not fall, in fact, running wild is actually falling!

In fact, the stars have been constantly transmitted, and the Milky Way mentioned in the question is rushing towards the giant source, but it can never be reached, which should mean that it is in a relatively stationary state and can never be realized.

All the matter in the whole universe is in constant motion, but many movements are easy for us to find, such as the movement of the moon around the earth, which was discovered in ancient times! But it's not so easy for the earth to revolve around the sun, but it's not difficult, at least Copernicus found out! So how does the solar system move in the Milky Way, and what about the Milky Way?

What about the pump group of galaxies?

How did Copernicus discover that the earth revolves around the sun? In fact, Heraclitus and Aristarchus in the ancient Greek era put forward the heliocentric theory, but there is no actual evidence, so from the ancient Greek era to the fifteenth century AD, about 1700 years of empty windows, so how did Copernicus discover the heliocentric theory? In fact, it's very simple, record the observations of the major planets at the same time every day, and then connect them to see it!

The picture above is the trajectory of Venus and Mercury and Jupiter and Saturn, of course, those two are really a bit long, so look at the trajectory of Mercury and Venus and Mars to know that the Sun is their center!

After removing the horizon, the orbit of the planets, the strange broken line is a retrograde phenomenon formed by the different orbiting speeds of the planets, combined with the observed phenomena on the earth, and the rotation of the earth that was still hypothetical at that time, can perfectly confirm the heliocentric theory!

How was the solar system found out revolving around the Milky Way? As early as the beginning of the 19th century, Herschel observed and studied the movement of a large number of stars, and found that the solar system as a whole is moving in the direction adjacent to the constellation Hercules and Lyra.

Because of the movement of the solar system, the heliosphere drags behind for a long time.

The earliest study of the rotation of the Milky Way was the end of the nineteenth century German astronomers, but at that time there was little data, can not be proved in observation, this has been to the book until 1924, Stromberg based on the asymmetry of the movement of the stars put forward the hypothesis of the rotation of the Milky Way, after 1926 Swedish astronomer Bertil Lindblad analysis of the Milky Way is also rotating, to 1927, Aort theoretically introduced the Milky Way poor rotation on the effect of the radial velocity of the star and the self-rotation of the silver meridian ( i.e., the Oort formula) and the analysis of the radial velocity of the star, the rotation of the Milky Way was confirmed.

In the early days, only the radial velocity of stars and self-directed optical observations were only 3-4 thousand parsecs around the solar system, but the development of radio astronomy after the 1940s made it possible for telescopes to observe the spectral displacement of hydrogen clouds in the Milky Way and find their motion, thus deriving the distribution of the poor rotation velocity of the Milky Way.

How does the Milky Way move? What about the local group of galaxies? What about the larger universe?

The movement of the Milky Way is more difficult to measure, astronomers have long found that the Andromeda Galaxy is coming towards the Milky Way, but the question is whether we go or do they come? That's a problem! But this problem was different in 1964 when American radio astronomers Arnold Penzias and Robert Wilson discovered the cosmic microwave background radiation!

It's most likely because the Milky Way wants to restructure a piece of space, but most likely because of the super-strong influence of gravity.

No one can guess the laws of nature, who knows what is going on.

No, it's absolutely impossible, the Milky Way is spinning at high speed, and the Hubble telescope confirmed that the star is redshifted, which is caused by the centrifugal force of rotation.
