Flying at 630 km per second

From a philosophical point of view, matter is the unity of absolute motion and relative rest, and everything in the world is in motion and changes. This view is equally valid when placed in the context of the entire universe.

Long ago, mankind always thought that the sun and the moon revolved around the earth and that the earth was a stationary individual. But with the gradual development of modern science, we realized that the Earth is always in motion.

The motion of the Earth

The Earth moves in two ways: rotation and rotation.

After astronomers' research, they found that the so-called sunrise and moonset are not the sun's rotation, but the earth's rotation around the sun and many other celestial bodies rotate around the sun like the earth.

The explanation for this phenomenon is mainly derived from Newton's law of gravity. Newton believed that the greater the mass of an object, the greater its gravitational force would be. As the only star in our solar system, the Sun's mass is dominant over the planets in our solar system, so the other planets are subject to the Sun's gravitational force and move in orbit around it.

Although we live on Earth and cannot visually see the Earth's trajectory, the average speed of the Earth's rotation can reach 29.8 km/s when viewed from the perspective of space.

In addition to its rotation, the Earth is also making a rotational motion. There are various theories about the reason for the Earth's rotation. Some believe that the Earth collided with space stars and got its starting speed, while others believe that the Earth has been carrying its speed since its birth. Either way, it iEarth is not in a static state.

The change of day and night, the alternation of seasons, is the passage of time that we can feel from the level of the Earth and is another way of presenting the movement of the Earth in the universe.

If the Earth, orbited by the Moon, moves, does the Sun move too? Will the Milky Way galaxy? The answer to all these questions is yes.

The Solar System and the Milky Way

The Sun is only one of the hundreds of billions of stars in our galaxy, and although the Milky Way is not a celestial body, it does allow the Sun to make a turnover motion around its silver center.

Scientists calculate that the Sun is about 2.4-2.7 play light years away from the center of the Milky Way and that it takes about 250 milit takers to move around the silver center at a speed of 220 kilometers per second for one week of its orbit. In this way, as the Sun moves around the silver center, the Earth is also displaced at some level by the Sun's gravity.

So how is it that the Milky Way can make the Sun move around its center?

In the Milky Way, besides young stars like the Sun, there are many older stars care many make the silvthat er center we see, which is about 20,000 light years in diameter. However, there comes a time when a star dies, and when they do, the interior collapses rapidly, resulting in the formation of a black hole. A black hole is a dense object with a gravitational force so strong that it can absorb all the matter that comes near it.

Therefore, scientists believe that there is a supermassive black hole in the center of the Milky Way and that the Sun isthatfluenced by this black hole to move around the silver center.

But what is surprising is that the whole galaxy is also in motion. According to conventional understanding, the motion of celestial bodies comes from higher-mass objects, but there are hundreds of billions of stars in the Milky Way. What is it that compels the galaxy, which already has such a huge mass, to move closer to it?

Moreover, scientists have observed that because of the movement of the Milky Way, the Earth is also darting through the universe at a speed of 630 km/s. Where are the Earth and the Milky Way going?

The existence of a giant gravitational source

We often say that there are people outside of us. The same applies to the universe. Beyond the Milky Way is the Virgo Cluster, which in turn is part of the Lani Kaiya Supercluster.

Given the inclusionary relationship, it seems unsurprising that a greater gravitational force would emerge. In the 1980s, scientists discovered an amazing phenomenon in the direction of the constellations Centaurus and Cepheus: there, they observed a large number of old galaxies, and galaxies colliding with each other, which also emitted a large number of number waves.

several and Centaurus, like Virgo, is part of the Lani Kaiya Supercluster, and their distribution shows that all galaxies are not close together. But here, galaxies are coming together and even colliding, and scientists have been studying them.

The study found that there is a large gravitational field, it is different from the black hole that can swallow matter, but with their great gravitational force makes the galaxies including the Milky Way hundreds of millions of light-years away from it, and this location is named "giant gravity source" by scientists.

Scientists speculate that the giant gravitational source belongs to a part of the Momentum cluster, about 250 million light-years away from the galaxy, and its mass is 3-5.4 × 10^16 times that of the Sun. The supersize and the supergravity make many galaxies affected by it.

Although the location of the giant gravitational source cannot be further studied due to its location from Earth just because of the occultation zone on the galactic disk. However, using redshifts, scientists have found that the Milky Way is moving toward the Virgo Cluster, which in turn is moving toward Centaurus, where the giant gravity source is located. Moreover, the speed of this motion is not low, and it is estimated that all galaxies and objects within them, which are affected by the giant gravity source, are moving in that direction at a speed of 600-700 kilometers per second.

The Earth is moving towards the giant gravity source at a speed of about 630 kilometers per second.

Epilogue

Although from the Earth's point of view alone it is speeding to another location in the universe, as a whole, the entire space environment in which the Earth is located is moving, and such synchronized motion instead leaves the Earth in a relatively static state.

What exactly will happen when the galaxy reaches Centaurus is still too far away for us. Before that happens, the first thing we need to figure out is how the giant gravitational source formed.
